Thanks for working on this! A quick first look with some ideas/suggestions

@mvo5 thanks for the review, I have applied some changes to the code.
I still do not know how I shall process the last assert:

E           AssertionError: expected call not found.
E           Expected: run(['gunzip', '--stdout', '/tmp/test_file.txt.gz'], encoding='utf8', check=True)
E             Actual: run(['gunzip', '--stdout', '/tmp/fake_file.txt.gz'], stdout=<_io.TextIOWrapper name='/tmp/test_file.txt' mode='w' encoding='utf8'>, check=True)

I mean - how to include stdout in the assert python query, or how to discard it.
If I understand correct assert was not expecting that there will be "two" outputs.

The here here seems to be from "test_file.txt.gz" vs "fake_file.txt.gz" not from the stdout?

@elkoniu Hey, this got the "stale" label now, but all it needs to get merged is a tiny fix in the unit tests (see previous comment). would you mind fixing it so that this can get in?

[elkoniu]

@mvo5 thanks for pointing this out, I have just updated the test case so it will not fail anymore :)
