Python脚本从另一个测试结果生成JUnit报告

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,而JUnit格式适合我.

所以我想检查是否有现成的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了.

相关问题.

Answer 1

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,只是想在不重新发明轮子的情况下输出JUnit XML中的结果.

我简单地看了一下上面larrycai建议的David Black的"python junit xml输出模块",但最后还是使用了另一个类似的包.不知道哪个更好,因为我只试过这个,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

要小心......他的自述文件中的例子有错误,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处理也存在一个错误,但我会引用你的问题#3,我也在github上报告,其中包括我的修复.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

Answer 2

你可以使用junitxml(Python JUnit XML reporter)

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

如果你有一个标准的unittest测试套件叫suite.你可以运行它,并将结果写入xml文件,如下所示:

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

另一个选择是使用nose和运行您的套件:

nosetests --with-xunit

我发现一个 python 模块https://bitbucket.org/db_atlass/python-junit-xml-output-module/，看起来适合我的需要。谢谢大卫·布莱克

# 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)
