This is very useful! Can I use this commercially? If so, with what kind of license?

Hi there

This code drops the name attribute of a test suite when merging.

I've added the name attribute to the code, however the merged reports, has as it's name, the last test suite.

This means that all the test suites test cases are reported as part of only one test suite (the last test suite, or, in this case the last Junit XML report).

I'm working on a fix. As soon as I have it I'll send merge request.

Thanks

Hi there, if i use this script, always get failures , test keyerrors although the sample result1.xml and result2.xml has these attributes.

failures += int(test_suite.attrib['failures'])
KeyError: 'failures

I am new to python,Am i missing anything?
Please guide

I don't think this snipped is maintained anymore, but junitparser should be a well suited replacement, since it also has a merge command.
