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

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 with pytest

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>

JUnit with nose

运行测试:

nosetests --with-xunit

nosetests.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):

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>

JUnit with nose2

您需要使用nose2.plugins.junitxml插件。您可以像通常那样使用配置文件配置nose2,也可以使用--plugin命令行选项配置nose2 --plugin nose2.plugins.junitxml --junit-xml tests

运行测试:

<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>

nose2-junit.xml:

tests.py

JUnit with unittest-xml-reporting

将以下内容附加到if __name__ == '__main__': import xmlrunner unittest.main(testRunner=xmlrunner.XMLTestRunner(output='test-reports'))

python tests.py

运行测试:

<?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>

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

答案 1 :(得分:20)

我会先用鼻子。现在内置了基本的XML报告。只需使用--with-xunit命令行选项,它将生成一个nosetests.xml文件。例如:

  

nosetests --with-xunit

然后在构建操作后添加“发布JUnit测试结果报告”,并使用nosetests.xml填写“测试报告XML”字段(假设您在$ WORKSPACE中运行了nosetests)。

答案 2 :(得分:9)

您可以安装unittest-xml-reporting程序包,以便为内置unittest添加生成XML的测试运行器。

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。

答案 3 :(得分:5)

我用过鼻子测试。有一些插件可以输出Jenkins的XML

答案 4 :(得分:3)

使用buildout时,我们使用collective.xmltestreport来生成JUnit样式的XML输出,也许它的source code或模块本身可能会有所帮助。

答案 5 :(得分:3)

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

从jenkins运行它作为shell,您可以将pytest_unit.xml中的报告作为工件。
