Better handle situations relating to text.txt in tests

[omerXfaruq]

Is your feature request related to a problem? Please describe.
test.txt started to cause issues in a unrelated test after small changes in #1845. I think we should find a better solution instead of using a file. Temporary files or creating&deleting the file in each test could work. Related discussion in slack

Additional context
We should break any dependency between the unrelated tests. test.txt was creating a dependency.
