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

所以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。

最佳答案

上面的 Corey 建议使用 junitxml，但我和 larrycai 在同一条船上，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，并且只想以 JUnit XML 格式输出结果，而无需重新发明轮子。

我简要地看了上面 larrycai 建议的 David Black 的“python junit xml 输出模块”，但最终还是使用了另一个类似的包。不确定哪个更好，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

当心...他的自述文件中的示例有错误并且不起作用。我在 github 上报告了错误(pypi 页面上包含 github 链接)。他的“prettyprint”arg 处理也有一个错误，但我会向您介绍我也在 github 上报告的问题 #3，其中包含我的修复程序。如果您下载源代码，您可以查看他的 test.py 单元测试，但这里也是我的测试脚本，我在其中测试/试验了几个示例(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:

#One version of JUnit XML schema: http://windyroad.org/dl/Open%20Source/JUnit.xsd
