How can I get "brew tests" to work?

[denismm]

I'm attempting to fix the ghostscript formula and following the instructions at https://docs.brew.sh/How-To-Open-a-Homebrew-Pull-Request but "brew tests" fails. Output attached. It's not at obvious to me what could be causing these errors.

The attached log is from running brew tests from fish but I tried under bash and still see the same errors.

If you're working on a PR that affects only the ghostscript formula, you need to run

brew test ghostscript
brew audit --strict ghostscript

You need to run brew tests only if you're making changes to brew itself (i.e. the code that lives in $(brew --repo)/Library/Homebrew).

The docs could probably be improved here. Thanks for following them so carefully, though.

Thank you for the clarification! :)
