"""
Output test reports in junit-xml format.
This plugin implements :func:`startTest`, :func:`testOutcome` and
:func:`stopTestRun` to compile and then output a test report in
junit-xml format. By default, the report is written to a file called
``nose2-junit.xml`` in the current working directory.
You can configure the output filename by setting ``path`` in a ``[junit-xml]``
section in a config file. Unicode characters which are invalid in XML 1.0
are replaced with the ``U+FFFD`` replacement character. In the case that your
software throws an error with an invalid byte string.
By default, the ranges of discouraged characters are replaced as well. This can
be changed by setting the ``keep_restricted`` configuration variable to
``True``.
By default, the arguments of parametrized and generated tests are not printed.
For instance, the following code:
.. code-block:: python
# a.py
from nose2 import tools
def test_gen():
def check(a, b):
assert a == b, '{}!={}'.format(a,b)
yield check, 99, 99
yield check, -1, -1
@tools.params('foo', 'bar')
def test_params(arg):
assert arg in ['foo', 'bar', 'baz']
Produces this XML by default:
.. code-block:: xml
<testcase classname="a" name="test_gen:1" time="0.000171">
<system-out />
</testcase>
<testcase classname="a" name="test_gen:2" time="0.000202">
<system-out />
</testcase>
<testcase classname="a" name="test_params:1" time="0.000159">
<system-out />
</testcase>
<testcase classname="a" name="test_params:2" time="0.000163">
<system-out />
</testcase>
But if ``test_fullname`` is ``True``, then the following XML is
produced:
.. code-block:: xml
<testcase classname="a" name="test_gen:1 (99, 99)" time="0.000213">
<system-out />
</testcase>
<testcase classname="a" name="test_gen:2 (-1, -1)" time="0.000194">
<system-out />
</testcase>
<testcase classname="a" name="test_params:1 ('foo')" time="0.000178">
<system-out />
</testcase>
<testcase classname="a" name="test_params:2 ('bar')" time="0.000187">
<system-out />
</testcase>
