Python unittests in Jenkins?

问题:

How do you get Jenkins to execute python unittest cases? Is it possible to JUnit style XML output from the builtin unittest package?

回答1:

sample tests:

tests.py:

# tests.py  import random try:     import unittest2 as unittest except ImportError:     import unittest  class SimpleTest(unittest.TestCase):     @unittest.skip("demonstrating skipping")     def test_skipped(self):         self.fail("shouldn't happen")      def test_pass(self):         self.assertEqual(10, 7 + 3)      def test_fail(self):         self.assertEqual(11, 7 + 3) 

JUnit with pytest

run the tests with:

py.test --junitxml results.xml tests.py 

results.xml:

self = <tests.SimpleTest testMethod=test_fail>      def test_fail(self): >       self.assertEqual(11, 7 + 3) E       AssertionError: 11 != 10  tests.py:16: AssertionError/home/damien/test-env/lib/python2.6/site-packages/_pytest/unittest.py:119: Skipped: demonstrating skipping

JUnit with nose

run the tests with:

nosetests --with-xunit 

nosetests.xml:

JUnit with nose2

You would need to use the nose2.plugins.junitxml plugin. You can configure nose2 with a config file like you would normally do, or with the --plugin command-line option.

run the tests with:

nose2 --plugin nose2.plugins.junitxml --junit-xml tests 

nose2-junit.xml:

Traceback (most recent call last):   File "/Users/damien/Work/test2/tests.py", line 18, in test_fail     self.assertEqual(11, 7 + 3) AssertionError: 11 != 10 

JUnit with unittest-xml-reporting

Append the following to tests.py

if __name__ == '__main__':     import xmlrunner     unittest.main(testRunner=xmlrunner.XMLTestRunner(output='test-reports')) 

run the tests with:

python tests.py 

test-reports/TEST-SimpleTest-20131001140629.xml:

回答2:

I would second using nose. Basic XML reporting is now built in. Just use the --with-xunit command line option and it will produce a nosetests.xml file. For example:

nosetests --with-xunit

Then add a "Publish JUnit test result report" post build action, and fill in the "Test report XMLs" field with nosetests.xml (assuming that you ran nosetests in $WORKSPACE).

回答3:

You can install the unittest-xml-reporting package to add a test runner that generates XML to the built-in unittest.

We use pytest, which has XML output built in (it's a command line option).

Either way, executing the unit tests can be done by running a shell command.

回答4:

I used nosetests. There are addons to output the XML for Jenkins

回答5:

When using buildout we use collective.xmltestreport to produce JUnit-style XML output, perhaps it's source code or the module itself could be of help.

回答6:

python -m pytest --junit-xml=pytest_unit.xml source_directory/test/unit || true # tests may fail 

Run this as shell from jenkins , you can get the report in pytest_unit.xml as artifact.
