"""`~unittest.TestCase` subclass for testing `.IOLoop`-based
asynchronous code.
The unittest framework is synchronous, so the test must be
complete by the time the test method returns. This means that
asynchronous code cannot be used in quite the same way as usual.
To write test functions that use the same ``yield``-based patterns
used with the `tornado.gen` module, decorate your test methods
with `tornado.testing.gen_test` instead of
`tornado.gen.coroutine`. This class also provides the `stop()`
and `wait()` methods for a more manual style of testing. The test
method itself must call ``self.wait()``, and asynchronous
callbacks should call ``self.stop()`` to signal completion.
By default, a new `.IOLoop` is constructed for each test and is available
as ``self.io_loop``. This `.IOLoop` should be used in the construction of
HTTP clients/servers, etc. If the code being tested requires a
global `.IOLoop`, subclasses should override `get_new_ioloop` to return it.
The `.IOLoop`'s ``start`` and ``stop`` methods should not be
called directly. Instead, use `self.stop <stop>` and `self.wait
<wait>`. Arguments passed to ``self.stop`` are returned from
``self.wait``. It is possible to have multiple ``wait``/``stop``
cycles in the same test.
Example::
# This test uses coroutine style.

@tornado.testing.gen_test

client = AsyncHTTPClient(self.io_loop)

Some libraries can produce a lot of logging output even when

with AsyncTestCase via multiple inheritance

that it is a `~logging.StreamHandler`. This is true for both
`logging.basicConfig` and the "pretty logging" configured by
`tornado.options`. It is not compatible with other log buffering
mechanisms, such as those provided by some test runners.

Use the unittest module's ``--buffer`` option instead, or `.ExpectLog`.

This test runner is essentially equivalent to `unittest.main` from
the standard library, but adds support for tornado-style option
parsing and log formatting.
The easiest way to run a test is via the command line::
python -m tornado.testing tornado.test.stack_context_test
See the standard library unittest module for ways in which tests can
be specified.
Projects with many tests may wish to define a test script like
``tornado/test/runtests.py``. This script should define a method
``all()`` which returns a test suite and then call
`tornado.testing.main()`. Note that even when a test script is
used, the ``all()`` test suite may be overridden by naming a
single test on the command line::
# Runs all tests
python -m tornado.test.runtests
# Runs one test
python -m tornado.test.runtests tornado.test.stack_context_test
Additional keyword arguments passed through to ``unittest.main()``.
For example, use ``tornado.testing.main(verbosity=2)``
to show many test details as they are run.
See http://docs.python.org/library/unittest.html#unittest.main
for full argument list.
