This test was inspired by bug #723 as testbrowser would pick up the wrong
button when having the same name twice in a form.
>>> browser = Browser()
When given a form with two submit buttons that have the same name:
>>> browser.open('''\
... <html><body>
... <form action="." method="post" enctype="multipart/form-data">
... <input type="submit" name="submit_me" value="GOOD" />
... <input type="submit" name="submit_me" value="BAD" />
... </form></body></html>
... ''') # doctest: +ELLIPSIS
GET / HTTP/1.1
...
We can specify the second button through it's label/value:
>>> browser.getControl('BAD')
<SubmitControl name='submit_me' type='submit'>
>>> browser.getControl('BAD').value
'BAD'
>>> browser.getControl('BAD').click() # doctest: +REPORT_NDIFF +ELLIPSIS
POST / HTTP/1.1
...
Content-type: multipart/form-data; ...
Content-disposition: form-data; name="submit_me"
<BLANKLINE>
BAD
...
This also works if the labels have whitespace around them (this tests a
regression caused by the original fix for the above):
>>> browser.open('''\
... <html><body>
... <form action="." method="post" enctype="multipart/form-data">
... <input type="submit" name="submit_me" value=" GOOD " />
... <input type="submit" name="submit_me" value=" BAD " />

GET / HTTP/1.1

Content-type: multipart/form-data; ...

def test_file_upload():

Fill in the form value using add_file:

def test_strip_linebreaks_from_textarea(self):
"""
>>> browser = Browser()
According to http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.1 line
break immediately after start tags or immediately before end tags must be
ignored, but real browsers only ignore a line break after a start tag.
So if we give the following form:
>>> browser.open('''
... <html><body>
... <form action="." method="post" enctype="multipart/form-data">
... <textarea name="textarea">
... Foo
... </textarea>
... </form></body></html>
... ''') # doctest: +ELLIPSIS
GET / HTTP/1.1
...
The value of the textarea won't contain the first line break:
>>> browser.getControl(name='textarea').value
'Foo\\n'
Of course, if we add line breaks, so that there are now two line breaks
after the start tag, the textarea value will start and end with a line
break.
>>> browser.open('''
... <html><body>
... <form action="." method="post" enctype="multipart/form-data">
... <textarea name="textarea">
...
... Foo
... </textarea>
... </form></body></html>
... ''') # doctest: +ELLIPSIS
GET / HTTP/1.1
...
>>> browser.getControl(name='textarea').value
'\\nFoo\\n'
Also, if there is some other whitespace after the start tag, it will be
preserved.
>>> browser.open('''
... <html><body>
... <form action="." method="post" enctype="multipart/form-data">
... <textarea name="textarea"> Foo </textarea>
... </form></body></html>
... ''') # doctest: +ELLIPSIS
GET / HTTP/1.1

' Foo '
"""
def test_relative_link():
"""
RFC 1808 specifies how relative URLs should be resolved, let's see
that we conform to it. Let's start with a simple example.
>>> browser = Browser()
>>> browser.open('''\
... <html><body>
... <a href="foo">link</a>
... </body></html>
... ''', url='http://localhost/bar') # doctest: +ELLIPSIS
GET /bar HTTP/1.1
...
>>> link = browser.getLink('link')
>>> link.url
'http://localhost/foo'
It's possible to have a relative URL consisting of only a query part. In
that case it should simply be appended to the base URL.
>>> browser.open('''\
... <html><body>
... <a href="?key=value">link</a>
... </body></html>
... ''', url='http://localhost/bar') # doctest: +ELLIPSIS
GET /bar HTTP/1.1
...
>>> link = browser.getLink('link')
>>> link.url
'http://localhost/bar?key=value'
In the example above, the base URL was the page URL, but we can also
specify a base URL using a <base> tag.
>>> browser.open('''\
... <html><head><base href="http://localhost/base" /></head><body>
... <a href="?key=value">link</a>
