Description: ***************
zope.testrunner

|buildstatus|_
|winbotstatus|_
.. contents::
This package provides a flexible test runner with layer support.
You can find more `detailed documentation`_ on PyPI or in the ``src/``
directory.
Getting started
***************
Buildout-based projects
=======================
zope.testrunner is often used for projects that use buildout_::
[buildout]
develop = .
parts = ... test ...
[test]
recipe = zc.recipe.testrunner
eggs = mypackage
The usual buildout process ::
python bootstrap.py
bin/buildout
creates a ``bin/test`` script that will run the tests for *mypackage*.
.. tip::
zc.recipe.testrunner_ takes care to specify the right
``--test-path`` option in the generated script. You can add
other options (such as ``--tests-pattern``) too; check
zc.recipe.testrunner_'s documentation for details.
Virtualenv-based projects
=========================
``pip install zope.testrunner`` and you'll get a ``zope-testrunner``
script. Run your tests with ::
zope-testrunner --test-path=path/to/your/source/tree
Your source code needs to be available for the testrunner to import,
so you need to run ``python setup.py install`` or ``pip install -e
.`` into the same virtualenv_.
Some useful command-line options to get you started
===================================================
-p show a percentage indicator
-v increase verbosity
-c colorize the output
-t test specify test names (one or more regexes)
-m module specify test modules (one or more regexes)
-s package specify test packages (one or more regexes)
--list-tests show names of tests instead of running them
-x stop on first error or failure
-D, --pdb enable post-mortem debugging of test failures
--help show *all* command-line options (there are many more!)
For example ::
bin/test -pvc -m test_foo -t TestBar
runs all TestBar tests from a module called test_foo.py.
Writing tests
=============
``zope.testrunner`` expects to find your tests inside your package
directory, in a subpackage or module named ``tests``. Test modules
in a test subpackage should be named ``test*.py``.
.. tip::
You can change these assumptions with ``--tests-pattern`` and
``--test-file-pattern`` test runner options.
Tests themselves should be classes inheriting from
``unittest.TestCase``, and if you wish to use doctests, please tell
the test runner where to find them and what options to use for them
in by supplying a function named ``test_suite``.
Example::
import unittest
import doctest
class TestArithmetic(unittest.TestCase):
def test_two_plus_two(self):
self.assertEqual(2 + 2, 4)
def doctest_string_formatting():
"""Test Python string formatting
>>> print('{} + {}'.format(2, 2))
2 + 2
"""
def test_suite():
return unittest.TestSuite([
unittest.makeSuite(TestArithmetic),
doctest.DocTestSuite(),
doctest.DocFileSuite('../README.txt',
optionflags=doctest.ELLIPSIS),
])
Test grouping
=============
In addition to per-package and per-module filtering, zope.testrunner
has other mechanisms for grouping tests:
* **layers** allow you to have shared setup/teardown code to be used
by a group of tests, that is executed only once, and not for each
test. Layers are orthogonal to the usual package/module structure
and are specified by setting the ``layer`` attribute on test
suites.
* **levels** allow you to group slow-running tests and not run them
by default. They're specified by setting the ``level`` attribute
on test suites to an int.
For more details please see the `detailed documentation`_.
Other features
==============
zope.testrunner can profile your tests, measure test coverage,
check for memory leaks, integrate with subunit_, shuffle the
test execution order, and run multiple tests in parallel.
For more details please see the `detailed documentation`_.

4.4.0 (2013-06-06)
==================
- Fix tests selection when the negative "!" pattern is used several times
(LP #1160965)
- Moved tests into a 'tests' subpackage.
- Made ``python -m zope.testrunner`` work again.

directory (https://github.com/zopefoundation/zope.testrunner/issues/6).
- Count test module import errors as errors (LP #1026576).
4.3.3 (2013-03-03)
==================
- Running layers in sub-processes did not use to work when run via
``python setup.py ftest`` since it tried to run setup.py with all the
command line options. It now detects ``setup.py`` runs and we run the test
runner directly.
4.3.2 (2013-03-03)
==================
- Fix ``SkipLayers`` class in cases where the distribution specifies a
``test_suite`` value.
4.3.1 (2013-03-02)

- Fixed a bug in the `ftest` command and added a test.
- Fixed a trivial test failure with Python 3 of the previous release.
4.3.0 (2013-03-02)
==================
- Expose `ftest` distutils command via an entry point.
- Added tests for ``zope.testrunner.eggsupport``.

PyPy 1.9.
- Fix --shuffle ordering on Python 3.2 to be the same as it was on older Python
versions.
- Fix --shuffle nondeterminism when multiple test layers are present.
Note: this will likely change the order of tests for the same --shuffle-seed.
- New option: --profile-directory. Use it in the test suite so that tests
executed by detox in parallel don't conflict.
- Use a temporary coverage directory in the test suite so that tests
executed by detox in parallel don't conflict.
- Fix --post-mortem (aka -D, --pdb) when a test module cannot be imported
or is invalid (LP #1119363).

whole unexpected success concept might be implemented later.
.. _`Unexpected success`: http://www.voidspace.org.uk/python/articles/unittest2.shtml#more-skipping
4.0.0 (2010-10-19)
==================
- Show more information about layers whose setup fails (LP #638153).
4.0.0b5 (2010-07-20)

distutils appears to munge the empty ``__init__.py`` file in the
``foo.bar`` egg used for testing into a directory.
- LP #580083: fix the ``bin/test`` script to run only tests from
``zope.testrunner``.

====================
- Having 'sampletests' in the MANIFEST.in gave warnings, but doesn't actually
seem to include any more files, so I removed it.
- Moved zope.testing.exceptions to zope.testrunner.exceptions. Now
zope.testrunner no longer requires zope.testing except for when running
its own tests.
4.0.0b1 (2010-04-29)
====================
- Initial release of the testrunner from zope.testrunner as its own module.

Detailed Documentation
**********************
Test Runner
===========
The testrunner module is used to run automated tests defined using the
unittest framework. Its primary feature is that it *finds* tests by
searching directory trees. It doesn't require the manual
concatenation of specific test suites. It is highly customizable and
should be usable with any project. In addition to finding and running
tests, it provides the following additional features:
- Test filtering using specifications of:
o test packages within a larger tree
o regular expression patterns for test modules
o regular expression patterns for individual tests
- Organization of tests into levels and layers
Sometimes, tests take so long to run that you don't want to run them
on every run of the test runner. Tests can be defined at different
levels. The test runner can be configured to only run tests at a
specific level or below by default. Command-line options can be
used to specify a minimum level to use for a specific run, or to run
all tests. Individual tests or test suites can specify their level
via a 'level' attribute. where levels are integers increasing from 1.
Most tests are unit tests. They don't depend on other facilities, or
set up whatever dependencies they have. For larger applications,
it's useful to specify common facilities that a large number of
tests share. Making each test set up and and tear down these
facilities is both ineffecient and inconvenient. For this reason,
we've introduced the concept of layers, based on the idea of layered
application architectures. Software build for a layer should be
able to depend on the facilities of lower layers already being set
up. For example, Zope defines a component architecture. Much Zope
software depends on that architecture. We should be able to treat
the component architecture as a layer that we set up once and reuse.
Similarly, Zope application software should be able to depend on the
Zope application server without having to set it up in each test.
The test runner introduces test layers, which are objects that can
set up environments for tests within the layers to use. A layer is
set up before running the tests in it. Individual tests or test
suites can define a layer by defining a `layer` attribute, which is
a test layer.

Simple Usage
============
The test runner consists of an importable module. The test runner is
used by providing scripts that import and invoke the `run` method from
the module. The `testrunner` module is controlled via command-line
options. Test scripts supply base and default options by supplying a
list of default command-line options that are processed before the
user-supplied command-line options are provided.
Typically, a test script does 2 things:
- Adds the directory containing the zope package to the Python
path.
- Calls the test runner with default arguments and arguments supplied
to the script.
Normally, it just passes default/setup arguments. The test runner
uses `sys.argv` to get the user's input.
This testrunner_ex subdirectory contains a number of sample packages
with tests. Let's run the tests found here. First though, we'll set
up our default options:
>>> import os.path
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
The default options are used by a script to customize the test runner
for a particular application. In this case, we use two options:
path
Set the path where the test runner should look for tests. This path
is also added to the Python path.
tests-pattern
Tell the test runner how to recognize modules or packages containing
tests.
Now, if we run the tests, without any other options:
>>> from zope import testrunner
>>> import sys
>>> sys.argv = ['test']
>>> testrunner.run_internal(defaults)

False
we see the normal testrunner output, which summarizes the tests run for
each layer. For each layer, we see what layers had to be torn down or
set up to run the layer and we see the number of tests run, with
results.
The test runner returns a boolean indicating whether there were
errors. In this example, there were no errors, so it returned False.
(Of course, the times shown in these examples are just examples.
Times will vary depending on system speed.)
Layers
======
A Layer is an object providing setup and teardown methods used to setup
and teardown the environment provided by the layer. It may also provide
setup and teardown methods used to reset the environment provided by the
layer between each test.
Layers are generally implemented as classes using class methods.
>>> class BaseLayer:
... def setUp(cls):
... log('BaseLayer.setUp')
... setUp = classmethod(setUp)
...
... def tearDown(cls):
... log('BaseLayer.tearDown')
... tearDown = classmethod(tearDown)
...
... def testSetUp(cls):
... log('BaseLayer.testSetUp')
... testSetUp = classmethod(testSetUp)
...
... def testTearDown(cls):
... log('BaseLayer.testTearDown')
... testTearDown = classmethod(testTearDown)
...
Layers can extend other layers. Note that they do not explicitly
invoke the setup and teardown methods of other layers - the test runner
does this for us in order to minimize the number of invocations.
>>> class TopLayer(BaseLayer):
... def setUp(cls):
... log('TopLayer.setUp')
... setUp = classmethod(setUp)
...
... def tearDown(cls):
... log('TopLayer.tearDown')
... tearDown = classmethod(tearDown)
...
... def testSetUp(cls):
... log('TopLayer.testSetUp')
... testSetUp = classmethod(testSetUp)
...
... def testTearDown(cls):
... log('TopLayer.testTearDown')
... testTearDown = classmethod(testTearDown)
...
Tests or test suites specify what layer they need by storing a reference
in the 'layer' attribute.
>>> import unittest
>>> class TestSpecifyingBaseLayer(unittest.TestCase):
... 'This TestCase explicitly specifies its layer'
... layer = BaseLayer
... name = 'TestSpecifyingBaseLayer' # For testing only
...
... def setUp(self):
... log('TestSpecifyingBaseLayer.setUp')
...
... def tearDown(self):
... log('TestSpecifyingBaseLayer.tearDown')
...
... def test1(self):
... log('TestSpecifyingBaseLayer.test1')
...
... def test2(self):
... log('TestSpecifyingBaseLayer.test2')
...
>>> class TestSpecifyingNoLayer(unittest.TestCase):
... 'This TestCase specifies no layer'
... name = 'TestSpecifyingNoLayer' # For testing only
... def setUp(self):
... log('TestSpecifyingNoLayer.setUp')
...
... def tearDown(self):
... log('TestSpecifyingNoLayer.tearDown')
...
... def test1(self):
... log('TestSpecifyingNoLayer.test')
...
... def test2(self):
... log('TestSpecifyingNoLayer.test')
...
Create a TestSuite containing two test suites, one for each of
TestSpecifyingBaseLayer and TestSpecifyingNoLayer.
>>> umbrella_suite = unittest.TestSuite()
>>> umbrella_suite.addTest(unittest.makeSuite(TestSpecifyingBaseLayer))
>>> no_layer_suite = unittest.makeSuite(TestSpecifyingNoLayer)
>>> umbrella_suite.addTest(no_layer_suite)
Before we can run the tests, we need to setup some helpers.
>>> from zope.testrunner import options
>>> from zope.testing.loggingsupport import InstalledHandler
>>> import logging
>>> log_handler = InstalledHandler('zope.testrunner.tests')
>>> def log(msg):
... logging.getLogger('zope.testrunner.tests').info(msg)
>>> def fresh_options():
... opts = options.get_options(['--test-filter', '.*'])
... opts.resume_layer = None
... opts.resume_number = 0
... return opts
Now we run the tests. Note that the BaseLayer was not setup when
the TestSpecifyingNoLayer was run and setup/torn down around the
TestSpecifyingBaseLayer tests.
>>> from zope.testrunner.runner import Runner
>>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite])
>>> succeeded = runner.run()
Running ...BaseLayer tests:
Set up ...BaseLayer in N.NNN seconds.
Ran 2 tests with 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Running zope.testrunner.layer.UnitTests tests:
Tear down ...BaseLayer in N.NNN seconds.
Set up zope.testrunner.layer.UnitTests in N.NNN seconds.
Ran 2 tests with 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Tearing down left over layers:
Tear down zope.testrunner.layer.UnitTests in N.NNN seconds.
Total: 4 tests, 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Now lets specify a layer in the suite containing TestSpecifyingNoLayer
and run the tests again. This demonstrates the other method of specifying
a layer. This is generally how you specify what layer doctests need.
>>> no_layer_suite.layer = BaseLayer
>>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite])
>>> succeeded = runner.run()
Running ...BaseLayer tests:
Set up ...BaseLayer in N.NNN seconds.
Ran 4 tests with 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Tearing down left over layers:
Tear down ...BaseLayer in N.NNN seconds.
Clear our logged output, as we want to inspect it shortly.
>>> log_handler.clear()
Now lets also specify a layer in the TestSpecifyingNoLayer class and rerun
the tests. This demonstrates that the most specific layer is used. It also
shows the behavior of nested layers - because TopLayer extends BaseLayer,
both the BaseLayer and TopLayer environments are setup when the
TestSpecifyingNoLayer tests are run.
>>> TestSpecifyingNoLayer.layer = TopLayer
>>> runner = Runner(options=fresh_options(), args=[], found_suites=[umbrella_suite])
>>> succeeded = runner.run()
Running ...BaseLayer tests:
Set up ...BaseLayer in N.NNN seconds.
Ran 2 tests with 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Running ...TopLayer tests:
Set up ...TopLayer in N.NNN seconds.
Ran 2 tests with 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Tearing down left over layers:
Tear down ...TopLayer in N.NNN seconds.
Tear down ...BaseLayer in N.NNN seconds.
Total: 4 tests, 0 failures, 0 errors and 0 skipped in N.NNN seconds.
If we inspect our trace of what methods got called in what order, we can
see that the layer setup and teardown methods only got called once. We can
also see that the layer's test setup and teardown methods got called for
each test using that layer in the right order.

Passing arguments explicitly
============================
In most of the examples here, we set up `sys.argv`. In normal usage,
the testrunner just uses `sys.argv`. It is possible to pass arguments
explicitly.
>>> import os.path
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
>>> from zope import testrunner
>>> testrunner.run_internal(defaults, 'test --layer 111'.split())
Running samplelayers.Layer111 tests:
Set up samplelayers.Layerx in N.NNN seconds.
Set up samplelayers.Layer1 in N.NNN seconds.

False
If options already have default values, then passing a different default will
override.
For example, --list-tests defaults to being turned off, but if we pass in a
different default, that one takes effect.
>>> defaults = [
... '--list-tests',
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
>>> from zope import testrunner
>>> testrunner.run_internal(defaults, 'test --layer 111'.split())

Verbose Output
==============
Normally, we just get a summary. We can use the -v option to get
increasingly more information.
If we use a single --verbose (-v) option, we get a dot printed for each
test:

>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> defaults = [

Sometimes, There are tests that you don't want to run by default.
For example, you might have tests that take a long time. Tests can
have a level attribute. If no level is specified, a level of 1 is
assumed and, by default, only tests at level one are run. to run
tests at a higher level, use the --at-level (-a) option to specify a higher
level. For example, with the following options:
>>> sys.argv = 'test -u -vv -t test_y1 -t test_y0'.split()
>>> testrunner.run_internal(defaults)

When you're trying to figure out why the test you want is not matched by the
pattern you specified, it is convenient to see which tests match your
specifications.
>>> sys.argv = 'test --all -m sample1 -t test_y0 --list-tests'.split()
>>> testrunner.run_internal(defaults)

Test Progress
=============
If the --progress (-p) option is used, progress information is printed and
a carriage return (rather than a new-line) is printed between
detail lines. Let's look at the effect of --progress (-p) at different
levels of verbosity.
>>> import os.path, sys
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
>>> sys.argv = 'test --layer 122 -p'.split()
>>> from zope import testrunner

(Note that, in the examples above and below, we show "##r##" followed by

Using a single level of verbosity causes test descriptions to be
output, but only if they fit in the terminal width. The default
width, when the terminal width can't be determined, is 80:

In this example, we also excluded tests with "NotMuch" in their names.
Unfortunately, the time data above doesn't buy us much because, in
practice, the line is cleared before there is time to see the

Autodetecting progress
----------------------
The --auto-progress option will determine if stdout is a terminal, and only enable
progress output if so.
Let's pretend we have a terminal
>>> class Terminal(object):
... def __init__(self, stream):
... self._stream = stream
... def __getattr__(self, attr):
... return getattr(self._stream, attr)
... def isatty(self):
... return True
>>> real_stdout = sys.stdout
>>> sys.stdout = Terminal(sys.stdout)

Disabling progress indication
-----------------------------
If -p or --progress have been previously provided on the command line (perhaps by a
wrapper script) but you do not desire progress indication, you can switch it off with
--no-progress:

Debugging
=========
The testrunner module supports post-mortem debugging and debugging
using `pdb.set_trace`. Let's look first at using `pdb.set_trace`.
To demonstrate this, we'll provide input via helper Input objects:
>>> class Input:
... def __init__(self, src):
... self.lines = src.split('\n')
... def readline(self):
... line = self.lines.pop(0)
... print(line)
... return line+'\n'
If a test or code called by a test calls pdb.set_trace, then the
runner will enter pdb at that point:
>>> import os.path, sys
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> from zope import testrunner
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
>>> real_stdin = sys.stdin
>>> sys.stdin = Input('p x\nc')
>>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$'
... ' -t set_trace1').split()
>>> try: testrunner.run_internal(defaults)
... finally: sys.stdin = real_stdin
... # doctest: +ELLIPSIS
Running zope.testrunner.layer.UnitTests tests:
...
> testrunner-ex/sample3/sampletests_d.py(27)test_set_trace1()
-> y = x
(Pdb) p x
1
(Pdb) c
Ran 1 tests with 0 failures, 0 errors and 0 skipped in 0.001 seconds.
...
False
Note that, prior to Python 2.4, calling pdb.set_trace caused pdb to
break in the pdb.set_trace function. It was necessary to use 'next'
or 'up' to get to the application code that called pdb.set_trace. In
Python 2.4, pdb.set_trace causes pdb to stop right after the call to
pdb.set_trace.
You can also do post-mortem debugging, using the --post-mortem (-D)
option:
>>> sys.stdin = Input('p x\nc')
>>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$'
... ' -t post_mortem1 -D').split()
>>> try: testrunner.run_internal(defaults)
... finally: sys.stdin = real_stdin

Note that the test runner exits after post-mortem debugging.
In the example above, we debugged an error. Failures are actually
converted to errors and can be debugged the same way:

>>> sys.argv = ('test -ssample3 --tests-pattern ^sampletests_d$'
... ' -t post_mortem_failure1 -D').split()

Layers that can't be torn down
==============================
A layer can have a tearDown method that raises NotImplementedError.
If this is the case and there are no remaining tests to run, the test
runner will just note that the tear down couldn't be done:
>>> import os.path, sys
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> from zope import testrunner
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... ]
>>> sys.argv = 'test -ssample2 --tests-pattern sampletests_ntd$'.split()
>>> testrunner.run_internal(defaults)

Ran 1 tests with 0 failures, 0 errors and 0 skipped in 0.000 seconds.
Tearing down left over layers:
Tear down sample2.sampletests_ntd.Layer ... not supported
False
If the tearDown method raises NotImplementedError and there are remaining
layers to run, the test runner will restart itself as a new process,
resuming tests where it left off:
>>> sys.argv = [testrunner_script, '--tests-pattern', 'sampletests_ntd$']
>>> testrunner.run_internal(defaults)

If you want to use pdb from a test in a layer that is run as a
subprocess, then rerun the test runner selecting *just* that layer so
that it's not run as a subprocess.
If a test is run in a subprocess and it generates output on stderr (as
stderrtest does), the output is ignored (but it doesn't cause a SubprocessError
like it once did).

Egg Support
===========
The `ftest` Setup Command
-------------------------
The `ftest` class is a proper `distutils` command and `zope.testrunner`
exposes it as such via an entry point.
>>> import pkg_resources
>>> ws = pkg_resources.WorkingSet()
>>> eps = dict([(ep.name, ep)
... for ep in ws.iter_entry_points('distutils.commands')])
>>> 'ftest' in eps
True
>>> eps['ftest']
EntryPoint.parse('ftest = zope.testrunner.eggsupport:ftest')
Let's now run this command:
>>> import zope.testrunner
>>> org_run = zope.testrunner.run
>>> def run(args):
... print(' '.join(args))
>>> zope.testrunner.run = run
>>> import os, tempfile, shutil
>>> tmpdir = tempfile.mkdtemp()
>>> srcdir = os.path.join(tmpdir, 'src')
>>> os.mkdir(srcdir)
>>> import setuptools.dist
>>> dist = setuptools.dist.Distribution(
... {'package_dir': {'': srcdir},
... 'script_name': __file__})
>>> from zope.testrunner.eggsupport import ftest
>>> ftest(dist).run()
IGNORE_ME --test-path .../src
Cleanup:
>>> zope.testrunner.run = org_run
>>> shutil.rmtree(tmpdir)
Skipping Tests with Layers
--------------------------
The ``SkipLayers`` scanning test loader can replace the standard test loader,
so that any tests that require layers are skipped. This is necessary, since
the standard setuptools testing facility does not handle layers. It can be
used as follows::
setup(
...
setup_requires=['eggtestinfo' # captures testing metadata in EGG-INFO
],
tests_require=['zope.testrunner',
],
...
test_loader='zope.testrunner.eggsupport:SkipLayers',
...
)
Let's now crete some test suites to make sure that all tests with layers are
properly skipped.
>>> import doctest
>>> import unittest
>>> all = unittest.TestSuite()
>>> class T1(unittest.TestCase):
... def test_t1(self):
... pass
>>> class T2(unittest.TestCase):
... layer = 'layer'
... def test_t2(self):
... pass
>>> T3 = doctest.DocTestSuite('zope.testrunner.find')
>>> T4 = doctest.DocTestSuite('zope.testrunner.options')
>>> T4.layer = 'layer'
>>> T5 = doctest.DocFileSuite('testrunner.txt', package='zope.testrunner.tests')
>>> T6 = doctest.DocFileSuite('testrunner-gc.txt', package='zope.testrunner.tests')
>>> T6.layer = 'layer'
>>> all = unittest.TestSuite((
... unittest.makeSuite(T1), unittest.makeSuite(T2), T3, T4, T5, T6,
... ))
Let's return those tests from the scan:
>>> from setuptools.command.test import ScanningLoader
>>> orig_loadTestsFromModule = ScanningLoader.loadTestsFromModule
>>> ScanningLoader.loadTestsFromModule = lambda *args: all
Now we can retrieve the modules from the layer skipping loader:
>>> from zope.testrunner.eggsupport import SkipLayers
>>> filtered = SkipLayers().loadTestsFromModule('zope.testrunner')
>>> len(filtered._tests)
3
>>> from pprint import pprint
>>> pprint(filtered._tests)
[<...T1 testMethod=test_t1>,
StartUpFailure (zope.testrunner.find),
.../zope/testrunner/tests/testrunner.txt]
Cleanup:
>>> ScanningLoader.loadTestsFromModule = orig_loadTestsFromModule
When the distribution specified a ``test_suite``, another method is used to
load the tests.
>>> orig_loadTestsFromNames = ScanningLoader.loadTestsFromNames
>>> ScanningLoader.loadTestsFromNames = lambda *args: all
Now we can retrieve the modules from the layer skipping loader:
>>> from zope.testrunner.eggsupport import SkipLayers
>>> filtered = SkipLayers().loadTestsFromNames(
... 'zope.testrunner.tests.test_suite', 'zope.testrunner')
>>> len(filtered._tests)
3
>>> from pprint import pprint
>>> pprint(filtered._tests)
[<...T1 testMethod=test_t1>,
StartUpFailure (zope.testrunner.find),
.../zope/testrunner/tests/testrunner.txt]
Cleanup:

Ignoring Tests
--------------
The ``trace`` module supports ignoring directories and modules based the test
selection. Only directories selected for testing should report coverage. The
test runner provides a custom implementation of the relevant API.
The ``TestIgnore`` class, the class managing the ignoring, is initialized by
passing the command line options. It uses the options to determine the
directories that should be covered.
>>> class FauxOptions(object):
... package = None
... test_path = [('/myproject/src/blah/foo', ''),
... ('/myproject/src/blah/bar', '')]
>>> from zope.testrunner import coverage
>>> from zope.testrunner.find import test_dirs
>>> ignore = coverage.TestIgnore(test_dirs(FauxOptions(), {}))
>>> ignore._test_dirs
['/myproject/src/blah/foo/', '/myproject/src/blah/bar/']
We can now ask whether a particular module should be ignored:
>>> ignore.names('/myproject/src/blah/foo/baz.py', 'baz')
False
>>> ignore.names('/myproject/src/blah/bar/mine.py', 'mine')
False
>>> ignore.names('/myproject/src/blah/foo/__init__.py', 'foo')
False
>>> ignore.names('/myproject/src/blah/hello.py', 'hello')
True
When running the test runner, modules are sometimes created from text
strings. Those should *always* be ignored:
>>> ignore.names('/myproject/src/blah/hello.txt', '<string>')
True
To make this check fast, the class implements a cache. In an early
implementation, the result was cached by the module name, which was a problem,
since a lot of modules carry the same name (not the Python dotted name
here!). So just because a module has the same name in an ignored and tested
directory, does not mean it is always ignored:
>>> ignore.names('/myproject/src/blah/module.py', 'module')
True
>>> ignore.names('/myproject/src/blah/foo/module.py', 'module')
False
Profiling
=========
The testrunner supports hotshot and cProfile profilers. Hotshot profiler
support does not work with python2.6
>>> import os.path, sys, tempfile
>>> profiler = '--profile=hotshot'
>>> if sys.hexversion >= 0x02060000:
... profiler = '--profile=cProfile'
The testrunner includes the ability to profile the test execution with hotshot
via the --profile option, if it a python <= 2.6
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> sys.path.append(directory_with_tests)
>>> tempdir = tempfile.mkdtemp(prefix='zope.testrunner-')
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... '--profile-directory', tempdir,
... ]
>>> sys.argv = [testrunner_script, profiler]
When the tests are run, we get profiling output.
>>> from zope import testrunner
>>> testrunner.run_internal(defaults)

The testrunner creates temnporary files containing hotshot profiler
data:
>>> os.listdir(tempdir)
['tests_profile.cZj2jt.prof', 'tests_profile.yHD-so.prof']
It deletes these when rerun. We'll delete these ourselves:
>>> import shutil
>>> shutil.rmtree(tempdir)
Running Without Source Code
===========================
The ``--usecompiled`` option allows running tests in a tree without .py
source code, provided compiled .pyc or .pyo files exist (without
``--usecompiled``, .py files are necessary).
We have a very simple directory tree, under ``usecompiled/``, to test
this. Because we're going to delete its .py files, we want to work
in a copy of that:
>>> import os.path, shutil, sys, tempfile
>>> directory_with_tests = tempfile.mkdtemp()
>>> NEWNAME = "unlikely_package_name"
>>> src = os.path.join(this_directory, 'testrunner-ex', 'usecompiled')
>>> os.path.isdir(src)
True
>>> dst = os.path.join(directory_with_tests, NEWNAME)
>>> os.path.isdir(dst)
False
Have to use our own copying code, to avoid copying read-only SVN files that
can't be deleted later.
>>> n = len(src) + 1
>>> for root, dirs, files in os.walk(src):
... dirs[:] = [d for d in dirs if d == "package"] # prune cruft
... os.mkdir(os.path.join(dst, root[n:]))
... for f in files:
... _ = shutil.copy(os.path.join(root, f),
... os.path.join(dst, root[n:], f))
Now run the tests in the copy:
>>> from zope import testrunner
>>> mydefaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^compiletest$',
... '--package', NEWNAME,
... '-vv',
... ]
>>> sys.argv = ['test']

False
If we delete the source files, it's normally a disaster: the test runner
doesn't believe any test files, or even packages, exist. Note that we pass
``--keepbytecode`` this time, because otherwise the test runner would
delete the compiled Python files too:
>>> for root, dirs, files in os.walk(dst):
... for f in files:
... if f.endswith(".py"):
... os.remove(os.path.join(root, f))
>>> testrunner.run_internal(mydefaults, ["test", "--keepbytecode"])
Running tests at level 1
Total: 0 tests, 0 failures, 0 errors and 0 skipped in N.NNN seconds.
False
Finally, passing ``--usecompiled`` asks the test runner to treat .pyc
and .pyo files as adequate replacements for .py files. Note that the
output is the same as when running with .py source above. The absence
of "removing stale bytecode ..." messages shows that ``--usecompiled``
also implies ``--keepbytecode``:
>>> if sys.version_info >= (3, 2):
... # PEP-3147: pyc files in __pycache__ directories cannot be
... # imported; legacy source-less imports need to use the legacy
... # layout

Repeating Tests
===============
The --repeat option can be used to repeat tests some number of times.
Repeating tests is useful to help make sure that tests clean up after
themselves.

Garbage Collection Control
==========================
When having problems that seem to be caused my memory-management
errors, it can be helpful to adjust Python's cyclic garbage collector
or to get garbage colection statistics. The --gc option can be used
for this purpose.
If you think you are getting a test failure due to a garbage
collection problem, you can try disabling garbage collection by
using the --gc option with a value of zero.
>>> import os.path, sys
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> defaults = ['--path', directory_with_tests]
>>> from zope import testrunner
>>> sys.argv = 'test --tests-pattern ^gc0$ --gc 0 -vv'.split()
>>> _ = testrunner.run_internal(defaults)
Cyclic garbage collection is disabled.

Tearing down left over layers:

Alternatively, if you think you are having a garbage collection
related problem, you can cause garbage collection to happen more often
by providing a low threshold:
>>> sys.argv = 'test --tests-pattern ^gc1$ --gc 1 -vv'.split()
>>> _ = testrunner.run_internal(defaults)
Cyclic garbage collection threshold set to: (1,)

You can specify up to 3 --gc options to set each of the 3 gc threshold
values:
>>> sys.argv = ('test --tests-pattern ^gcset$ --gc 701 --gc 11 --gc 9 -vv'
... .split())
>>> _ = testrunner.run_internal(defaults)

Specifying more than 3 --gc options is not allowed:
>>> from six import StringIO
>>> out = StringIO()
>>> stdout = sys.stdout
>>> sys.stdout = out
>>> sys.argv = ('test --tests-pattern ^gcset$ --gc 701 --gc 42 --gc 11 --gc 9 -vv'

Garbage Collection Statistics
-----------------------------
You can enable gc debugging statistics using the --gc-options (-G)
option. You should provide names of one or more of the flags
described in the library documentation for the gc module.
The output statistics are written to standard error.
>>> from six import StringIO
>>> err = StringIO()

Debugging Memory Leaks
======================
The --report-refcounts (-r) option can be used with the --repeat (-N)
option to detect and diagnose memory leaks. To use this option, you
must configure Python with the --with-pydebug option. (On Unix, pass
this option to configure and then build Python.)
>>> import os.path, sys
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')

Total: 68 tests, 0 failures, 0 errors and 0 skipped in N.NNN seconds.
Each layer is repeated the requested number of times. For each
iteration after the first, the system refcount and change in system
refcount is shown. The system refcount is the total of all refcount in
the system. When a refcount on any object is changed, the system
refcount is changed by the same amount. Tests that don't leak show
zero changes in systen refcount.
Let's look at an example test that leaks:
>>> sys.argv = 'test --tests-pattern leak -N4 -r'.split()
>>> _ = testrunner.run_internal(defaults)
Running zope.testrunner.layer.UnitTests tests:...

It is instructive to analyze the results in some detail. The test
being run was designed to intentionally leak:
class ClassicLeakable:
def __init__(self):
self.x = 'x'
class Leakable(object):
def __init__(self):
self.x = 'x'
leaked = []
class TestSomething(unittest.TestCase):
def testleak(self):
leaked.append((ClassicLeakable(), Leakable(), time.time()))
Let's go through this by type.
float, leak.ClassicLeakable, leak.Leakable, and tuple
We leak one of these every time. This is to be expected because
we are adding one of these to the list every time.
str
We don't leak any instances, but we leak 4 references. These are
due to the instance attributes avd values.
dict
We leak 2 of these, one for each ClassicLeakable and Leakable
instance.
classobj
We increase the number of classobj instance references by one each
time because each ClassicLeakable instance has a reference to its
class. This instances increases the references in it's class,
which increases the total number of references to classic classes
(clasobj instances).
type
For most interations, we increase the number of type references by
one for the same reason we increase the number of clasobj
references by one. The increase of the number of type references
by 3 in the second iteration is puzzling, but illustrates that
this sort of data is often puzzling.
int
The change in the number of int instances and references in this
example is a side effect of the statistics being gathered. Lots
of integers are created to keep the memory statistics used here.
The summary statistics include the sum of the detail refcounts. (Note
that this sum is less than the system refcount. This is because the
detailed analysis doesn't inspect every object. Not all objects in the
system are returned by sys.getobjects.)
Knitting in extra package directories
=====================================
Python packages have __path__ variables that can be manipulated to add
extra directories cntaining software used in the packages. The
testrunner needs to be given extra information about this sort of
situation.
Let's look at an example. The testrunner-ex-knit-lib directory
is a directory that we want to add to the Python path, but that we
don't want to search for tests. It has a sample4 package and a
products subpackage. The products subpackage adds the
testrunner-ex-knit-products to it's __path__. We want to run tests
from the testrunner-ex-knit-products directory. When we import these
tests, we need to import them from the sample4.products package. We
can't use the --path option to name testrunner-ex-knit-products.
It isn't enough to add the containing directory to the test path
because then we wouldn't be able to determine the package name
properly. We might be able to use the --package option to run the
tests from the sample4/products package, but we want to run tests in
testrunner-ex that aren't in this package.
We can use the --package-path option in this case. The --package-path
option is like the --test-path option in that it defines a path to be
searched for tests without affecting the python path. It differs in
that it supplied a package name that is added a profex when importing
any modules found. The --package-path option takes *two* arguments, a
package name and file path.
>>> import os.path, sys
>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> sys.path.append(os.path.join(this_directory, 'testrunner-ex-pp-lib'))

... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',
... '--package-path',
... os.path.join(this_directory, 'testrunner-ex-pp-products'),
... 'sample4.products',
... ]

testrunner Edge Cases
=====================
This document has some edge-case examples to test various aspects of
the test runner.
Separating Python path and test directories
-------------------------------------------
The --path option defines a directory to be searched for tests *and* a
directory to be added to Python's search path. The --test-path option
can be used when you want to set a test search path without also
affecting the Python path:

>>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
>>> from zope import testrunner
>>> defaults = [

Errors and Failures
===================
Let's look at tests that have errors and failures, first we need to make a
temporary copy of the entire testing directory (except .svn files which may
be read only):
>>> import os.path, sys, tempfile, shutil
>>> tmpdir = tempfile.mkdtemp()
>>> directory_with_tests = os.path.join(tmpdir, 'testrunner-ex')
>>> source = os.path.join(this_directory, 'testrunner-ex')
>>> n = len(source) + 1
>>> for root, dirs, files in os.walk(source):
... dirs[:] = [d for d in dirs if d != ".svn"] # prune cruft
... os.mkdir(os.path.join(directory_with_tests, root[n:]))
... for f in files:
... _ = shutil.copy(os.path.join(root, f),
... os.path.join(directory_with_tests, root[n:], f))
>>> from zope import testrunner
>>> defaults = [
... '--path', directory_with_tests,
... '--tests-pattern', '^sampletestsf?$',

We see that we get an error report and a traceback for the failing
test. In addition, the test runner returned True, indicating that
there was an error.
If we ask for verbosity, the dotted output will be interrupted, and
there'll be a summary of the errors at the end of the test:

This can be a bit confusing, especially when there are enough tests
that they scroll off a screen. Often you just want to see the first
failure. This can be accomplished with the -1 option (for "just show
me the first failed example in a doctest" :)

Getting diff output for doctest failures
----------------------------------------
If a doctest has large expected and actual output, it can be hard to
see differences when expected and actual output differ. The --ndiff,
--udiff, and --cdiff options can be used to get diff output of various
kinds.

Here, the actual output uses the word "and" rather than the word "an",
but it's a bit hard to pick this out. We can use the various diff
outputs to see this better. We could modify the test to ask for diff
output, but it's easier to use one of the diff options.
The --ndiff option requests a diff using Python's ndiff utility. This
is the only method that marks differences within lines as well as
across lines. For example, if a line of expected output contains digit
1 where actual output contains letter l, a line is inserted with a
caret marking the mismatching column positions.

Testing-Module Import Errors
----------------------------
If there are errors when importing a test module, these errors are
reported. In order to illustrate a module with a syntax error, we create
one now: this module used to be checked in to the project, but then it was
included in distributions of projects using zope.testrunner too, and distutils
complained about the syntax error when it compiled Python files during
installation of such projects. So first we create a module with bad syntax:
>>> badsyntax_path = os.path.join(directory_with_tests,
... "sample2", "sampletests_i.py")
>>> f = open(badsyntax_path, "w")
>>> print("importx unittest", file=f) # syntax error
>>> f.close()
Then run the tests:
>>> sys.argv = ('test --tests-pattern ^sampletests(f|_i)?$ --layer 1 '
... ).split()
>>> testrunner.run_internal(defaults)
... # doctest: +NORMALIZE_WHITESPACE

Reporting Errors to Calling Processes
-------------------------------------
The testrunner returns the error status, indicating that the tests
failed. This can be useful for an invoking process that wants to
monitor the result of a test run.
This is applied when invoking the testrunner using the ``run()`` function
instead of ``run_internal()``:
>>> sys.argv = (
... 'test --tests-pattern ^sampletests_1$'.split())
>>> try:
... testrunner.run(defaults)
... except SystemExit as e:
... print('exited with code', e.code)
... else:
... print('sys.exit was not called')
... # doctest: +ELLIPSIS
