Outputting XML Test Reports


New in version 0.2

Output test reports in junit-xml format.

This plugin implements startTest(), testOutcome() and 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:

# 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:

<testcase classname="a" name="test_gen:1" time="0.000171">
    <system-out />
<testcase classname="a" name="test_gen:2" time="0.000202">
    <system-out />
<testcase classname="a" name="test_params:1" time="0.000159">
    <system-out />
<testcase classname="a" name="test_params:2" time="0.000163">
    <system-out />

But if test_fullname is True, then the following XML is produced:

<testcase classname="a" name="test_gen:1 (99, 99)" time="0.000213">
    <system-out />
<testcase classname="a" name="test_gen:2 (-1, -1)" time="0.000194">
    <system-out />
<testcase classname="a" name="test_params:1 ('foo')" time="0.000178">
    <system-out />
<testcase classname="a" name="test_params:2 ('bar')" time="0.000187">
    <system-out />

Enable this Plugin

This plugin is built-in, but not loaded by default.

Even if you specify always-on = True in the configuration, it will not run unless you also enable it. You can do so by putting the following in a unittest.cfg or nose2.cfg file

plugins = nose2.plugins.junitxml

The plugins parameter may contain a list of plugin names, including nose2.plugins.junitxml

Configuration [junit-xml]


Sample configuration

The default configuration is equivalent to including the following in a unittest.cfg file.

always-on = False
keep_restricted = False
path = nose2-junit.xml
test_fullname = False
test_properties = None

Command-line options

-X DEFAULT, --junit-xml DEFAULT

Generate junit-xml output report

Plugin class reference: JUnitXmlReporter

class nose2.plugins.junitxml.JUnitXmlReporter[source]

Output junit-xml test report to file


Count test, record start time


Output xml tree to file


Add test outcome to xml tree

Sample output

The XML test report for nose2’s sample scenario with tests in a package looks like this:
