如何让Jenkins执行python单元测试用例?是否可以使用内置的unittest包输出JUnit样式的XML?

样本测试:

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与pytest

使用以下方法运行测试:

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

.xml结果:

<?xml version="1.0" encoding="utf-8"?>
<testsuite errors="0" failures="1" name="pytest" skips="1" tests="2" time="0.097">
    <testcase classname="tests.SimpleTest" name="test_fail" time="0.000301837921143">
        <failure message="test failure">self = &lt;tests.SimpleTest testMethod=test_fail&gt;

    def test_fail(self):
&gt;       self.assertEqual(11, 7 + 3)
E       AssertionError: 11 != 10

tests.py:16: AssertionError</failure>
    </testcase>
    <testcase classname="tests.SimpleTest" name="test_pass" time="0.000109910964966"/>
    <testcase classname="tests.SimpleTest" name="test_skipped" time="0.000164031982422">
        <skipped message="demonstrating skipping" type="pytest.skip">/home/damien/test-env/lib/python2.6/site-packages/_pytest/unittest.py:119: Skipped: demonstrating skipping</skipped>
    </testcase>
</testsuite>

JUnit

使用以下方法运行测试:

nosetests --with-xunit

xml:

<?xml version="1.0" encoding="UTF-8"?>
<testsuite name="nosetests" tests="3" errors="0" failures="1" skip="1">
    <testcase classname="tests.SimpleTest" name="test_fail" time="0.000">
        <failure type="exceptions.AssertionError" message="11 != 10">
            <![CDATA[Traceback (most recent call last):
File "/opt/python-2.6.1/lib/python2.6/site-packages/unittest2-0.5.1-py2.6.egg/unittest2/case.py", line 340, in run
testMethod()
File "/home/damien/tests.py", line 16, in test_fail
self.assertEqual(11, 7 + 3)
File "/opt/python-2.6.1/lib/python2.6/site-packages/unittest2-0.5.1-py2.6.egg/unittest2/case.py", line 521, in assertEqual
assertion_func(first, second, msg=msg)
File "/opt/python-2.6.1/lib/python2.6/site-packages/unittest2-0.5.1-py2.6.egg/unittest2/case.py", line 514, in _baseAssertEqual
raise self.failureException(msg)
AssertionError: 11 != 10
]]>
        </failure>
    </testcase>
    <testcase classname="tests.SimpleTest" name="test_pass" time="0.000"></testcase>
    <testcase classname="tests.SimpleTest" name="test_skipped" time="0.000">
        <skipped type="nose.plugins.skip.SkipTest" message="demonstrating skipping">
            <![CDATA[SkipTest: demonstrating skipping
]]>
        </skipped>
    </testcase>
</testsuite>

有鼻孔的JUnit 2

您需要使用nose2.plugins.junitxml插件。您可以配置nose2使用配置文件,如您通常所做的那样,或者使用--plugin命令行选项。

使用以下方法运行测试:

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

nose 2-jun it.xml:

<testsuite errors="0" failures="1" name="nose2-junit" skips="1" tests="3" time="0.001">
  <testcase classname="tests.SimpleTest" name="test_fail" time="0.000126">
    <failure message="test failure">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
</failure>
  </testcase>
  <testcase classname="tests.SimpleTest" name="test_pass" time="0.000095" />
  <testcase classname="tests.SimpleTest" name="test_skipped" time="0.000058">
    <skipped />
  </testcase>
</testsuite>

带有unittest-xml-Reporting的JUnit

将下列内容附加到tests.py

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

使用以下方法运行测试:

python tests.py

...

<?xml version="1.0" ?>
<testsuite errors="1" failures="0" name="SimpleTest-20131001140629" tests="3" time="0.000">
    <testcase classname="SimpleTest" name="test_pass" time="0.000"/>
    <testcase classname="SimpleTest" name="test_fail" time="0.000">
        <error message="11 != 10" type="AssertionError">
<![CDATA[Traceback (most recent call last):
  File "tests.py", line 16, in test_fail
    self.assertEqual(11, 7 + 3)
AssertionError: 11 != 10
]]>     </error>
    </testcase>
    <testcase classname="SimpleTest" name="test_skipped" time="0.000">
        <skipped message="demonstrating skipping" type="skip"/>
    </testcase>
    <system-out>
<![CDATA[]]>    </system-out>
    <system-err>
<![CDATA[]]>    </system-err>
</testsuite>

基本的XML报告现在内置。只要使用--with-xunit命令行选项,它就会生成一个nosetests.xml文件。例如:

nosetests --with-xunit

然后添加一个“PublishJUnit测试结果报告”POST构建操作,并使用nosetests.xml填充“TestReportXML”字段(假设您在$工作区中运行nosetest)。
