如何使用unittest的stdout生成xml测试报告？

Question

Assume I have a python tool to build and run unittest , eg python3 build_and_test ... .

Is there any way to parse stdout of unittest and generate xml(junit) report? I have refer to unittest-xml-reporting , but it seems that I must change my build_and_test code and I can't do that. How can I just parse the stdout of unittest and create xml reports?

Answer 1

You need to take 2 steps:

1. Extend unittest.TextTestRunner and override _makeResult(). See https://docs.python.org/3.4/library/unittest.html#unittest.TextTestRunner._makeResult

2. Implement your own version of unittest.TestResult. See https://docs.python.org/3.4/library/unittest.html#unittest.TestResult . Your code will be code upon various events. Example: When there is a testing error the methid addError will be called. See https://docs.python.org/3.4/library/unittest.html#unittest.TestResult.addError

Now you have control of the various events and you will be able to create the XML report.
