Jenkins中的Python单元测试?

问题:Jenkins中的Python单元测试?

您如何让Jenkins执行python unittest案例?是否可以从内置unittest包中输出JUnit样式的XML ?

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

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)

带有pytest的JUnit

使用以下命令运行测试:

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

results.xml:

<?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>

带鼻子的JUnit

使用以下命令运行测试:

nosetests --with-xunit

鼻子测试.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):

        </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>

带有鼻子的JUnit2

您将需要使用nose2.plugins.junitxml插件。您可以nose2像通常一样使用配置文件进行配置,也可以使用--plugin命令行选项进行配置。

使用以下命令运行测试:

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

鼻子2-junit.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>

具有unittest-xml-reporting的JUnit

将以下内容附加到 tests.py

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

使用以下命令运行测试:

python tests.py

测试报告/TEST-SimpleTest-20131001140629.xml:

<?xml version="1.0" ?>
<testsuite errors="1" failures="0" name="SimpleTest-20131001140629" tests="3" time="0.000">

    <testcase classname="SimpleTest" name="test_fail" time="0.000">

    </testcase>

    <system-out>

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:

<?xml version="1.0" encoding="utf-8"?>
<testsuite errors="0" failures="1" name="pytest" skips="1" tests="2" time="0.097">

    def test_fail(self):

JUnit with nose

run the tests with:

nosetests --with-xunit

nosetests.xml:

<?xml version="1.0" encoding="UTF-8"?>

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:

<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>

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:

<?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">

    <testcase classname="SimpleTest" name="test_skipped" time="0.000">

我会第二次使用鼻子。现在已经内置了基本的XML报告。只需使用–with-xunit命令行选项,它就会生成一个nosetests.xml文件。例如:

鼻子测试–with-xunit

然后添加一个“发布JUnit测试结果报告”后生成操作,并使用nasesttests.xml填充“测试报告XML”字段(假设您在$ WORKSPACE中运行了鼻子测试)。

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 2

您可以安装unittest-xml-reporting包,以将生成XML的测试运行器添加到内置unittest

我们使用pytest,它内置了XML输出(这是一个命令行选项)。

无论哪种方式,都可以通过运行shell命令来执行单元测试。

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 3

我用鼻子测试。有一些插件可以为Jenkins输出XML

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


回答 4

当使用buildout时,我们collective.xmltestreport会产生JUnit风格的XML输出,也许它是源代码,或者模块本身可能会有所帮助。

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.

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

从jenkins作为shell运行它,您可以在pytest_unit.xml中作为工件获取报告。

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.
