从另一个测试resu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。我想使用Jenkins来显示结果，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解析代码。

上面提到的Corey建议使用junitxml，但我和larrycai是同一条船，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，只想将结果输出到JUnit XML中，而不需要重新设计轮子。

我简要地看了一下上面larrycai建议的David Black的“python junit xml输出模块”，但最后使用了另一个类似的包。不知道哪一个更好，因为我只尝试了这一个，但它最终为我工作得很好。

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

小心…他自述中的例子有错误，不起作用。我在github上报告了错误（github链接包含在pypi页面中）。他的“prettyprint”arg处理也有一个bug，但我将向您介绍我在github上报告的第3期，其中包括我的修复。如果您下载了源代码，您可以查看他的test.py单元测试，但这里也是我的测试脚本，在这里我测试/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
