Avocado is a set of tools and libraries to help with automated testing. One can call it a test framework with benefits. Native tests are written in Python and they follow the unittest pattern, but any executable can serve as a test.

@Geet2 Hi! thanks for your bug report. We have recently tested avocado with avocado-misc-tests and they worked fine (reference: https://github.com/avocado-framework/avocado/issues/4969#issuecomment-943864631) Could you please try against the latest version from github (commit a74bc734330c9c9f2b91df4e796c4422ac57b918) and the latest from avocado-misc-tests as well? Thanks

Hi @Geet2 , thanks for reporting this bug. Given the nature of the test, it's easy to assume that processes may have been in uninterruptible state. Having said that, Avocado should not have crashed, but signaled its failure to destroy the process.

This is reported against the legacy runner, which as its name imply, is under no further development. I suggest we take this use case (uninterruptible process) in consideration with the open issue #4994 .

As per suggestion on this thread, I ran the same test (avocado-misc-tests/fs/xfstests.py) with latest avocado (92) on the same system.

Thanks @Geet2.

@Geet2 Hi, I'm going to close this issue. I couldn't reproduce the problem at the time you reported it and the legacy runner (the one you're using) is being dropped from avocado. As @clebergnu mentioned, here avocado should not have crashed and instead signaled its failure to destroy the process. This is handled in a separate bug report because this will be properly fixed in our new default runner. Thanks for your bug report!
