Append mode for junitxml output

[jxramos]

I just came across this SO post over here https://stackoverflow.com/questions/60834564/how-to-append-different-pytest-tests-to-the-same-junit-xml-file-instead-of-overr, and it asked an interesting question if it was possible to write to the same junit file path and have pytest do an append to xml rather than overwrite. I commented on the post about how we have the -log-file-mode=a could there be room likewise for a -junitxml-file-mode=a that perhaps grew the <testsuites> element <testsuite> by <testsuite> each invocation?

I wonder if we don't see this more because many junit parsers like in bamboo and jenkins would mask the testsuite variation perhaps. I'm curious how they would be have in fact with a file containing a multi element <testsuites> entry.

There are tools to merge or combine junitxml files

Personally i completely avoid junitxml

Indeed, most systems support parsing multiple junitxml files a single "unit".
