Planemo test output files

Hi there,

I’m currently wrapping a tool and running into an issue with the output files during testing. When I run planemo test with the --no_cleanup flag, I can see that the output files are correctly generated inside the temporary working directory. However, these files don’t appear in my test-data directory, and as a result, the tests always fail.

When I use the --update_test_data flag, the expected output files are created in test-data, but they are unfortunately empty.

What could I be missing here?
