从另一个测试结果生成JUnit报告的Python脚本

Question

我有一个验收测试用例，结果是纯文本。我想用Jenkins来显示结果，JUnit格式适合我。

因此，我想检查是否有现有的python代码来生成JUnit格式的XML，这样我就可以轻松地添加我的解析代码。

相关问题。

Answer 1

Corey建议使用junitxml，但我和larrycai的处境相同，因为我没有编写单元测试来测试Python代码。我正在编写Python脚本来进行黑盒系统测试，只想在不重新设计轮子的情况下用JUnitXML输出结果。

我简单地看了一下上面larrycai建议的David Black的"python-junit xml输出模块"，但最终得到了另一个类似的包。不确定哪一个更好，因为我只试过这个，但它最终对我来说效果很好。

只有一个字符不同，但包是"junit xml"：https://pypi.python.org/pypi/junit-xml/1.0

小心。。。他的自述中的例子有错误，不起作用。我报告了github上的错误(pypi页面上包含github链接)。他的"prettyprint"arg处理也有一个错误，但我将向您介绍我在github上报告的问题#3，其中包含了我的修复。如果你下载了源代码，你可以查看他的test.py单元测试，但这里也是我的测试脚本，我在其中测试/实验了几个例子(使用Python 3.3)：

#junit-xml 1.0 downloaded from https://pypi.python.org/pypi/junit-xml
from junit_xml import TestSuite, TestCase
#Good article that has examples of how Jenkins parses JUnit XML to display output:
#http://nelsonwells.net/2012/09/how-jenkins-ci-parses-and-displays-junit-output/
#One version of JUnit XML schema: http://windyroad.org/dl/Open%20Source/JUnit.xsd

您可以使用junitxml(Python JUnit XML报告程序)

关于PyPI：http://pypi.python.org/pypi/junitxml

如果您有一个名为suite的标准unittest测试套件。您可以运行它，并将结果写入这样的xml文件：

import junitxml
fp = file('results.xml', 'wb')
result = junitxml.JUnitXmlResult(fp)
result.startTestRun()
TestSuite(suite).run(result)
result.stopTestRun()

或者发现测试并将xml打印到stdout:

python -m junitxml.main discover

---

另一个选项是使用nose并使用运行您的套件

nosetests --with-xunit

Answer 3

collective.recipe.xmltestreport构建配方包正是这样做的。它获取测试运行程序的输出，并创建一个适合JUnit的XML文件。然而，它是特定于构建的，并使用zope.testrunner测试运行程序包。

如果切换到构建不是你的选择，你可以研究它的源代码来提取重要部分。

我发现了一个python模块https://bitbucket.org/db_atlass/python-junit-xml-output-module/，看起来很适合我的需要。大卫·布莱克在那里

# code snippet for the usage
""" a short example of how to use this module """
test_cases = []
for i in range(0, 5):
type_c = ""
if i % 2 == 0:
type_c = "failure"
test_cases.append(TestCase(i, str(i) + "contents", type_c) )
junit_xml = JunitXml("demo test example", test_cases)

这里我从github得到了另一个包https://github.com/kyrus/python-junit-xml

Answer 6

这里的答案很好：(有很多方法)詹金斯的Python单元测试？

IMHO最好的方法是编写python-unittest测试和安装pytest(类似于"yum-install-pytest")以安装py.test。然后运行这样的测试：'py.test--junitxml results.xml test.py'。您可以运行任何unittest python脚本并获得jUnit.xml结果。

https://docs.python.org/2.7/library/unittest.html

在jenkins构建配置中，构建后操作添加一个带有result.xml的"发布JUnit测试结果报告"操作以及您生成的任何其他测试结果文件。
