Thanks for the PR! .taprc also needs removing as part of this (but kept in .gitignore).

Could you run npm run lint:fix? it should fix the CI

The issue here is using const tmpdir = fs.mkdtempSync(path.join(os.tmpdir(), '')) instead of the previous t.testDir() that was implemented directly inside tap.
Do you have any suggestions about this? Perhaps there are other projects where a similar approach has been implemented that I could use as a reference?"

Thank you in advance for your answer.

If i check the testdir implementation I think it was using a path in the project's folder (such as .tap/fixtures).
So I think we may not create the ostmp by a random folder in a similar way (that we must add to the gitignore)
