If we treat warnings as errors with pytest (via
-Werror
or config file change), tests usingsubprocess
code path will fail because we get a warning about an unclosed file onstderr
.Ultimately, the entire
Runner.run()
method probably needs reworked so that it is not so complex, and we can use better/safer coding methods, such as context managers on the open file handles. As it is now, using context managers on these file handles is a major pain since there is so much code between opening them and where we need to guarantee they are closed.Provided test will fail without the code changes to close
stdout
/stderr
