Fix the path for included files in umbrella apps

[tomasz-tomczyk]

Hello! I ran into an issue where Credo.Check.Refactor.PassAsyncInTestCases would not flag issues when running mix credo from the root of an umbrella application, but cd-ing into apps/app_web and running it from there would correctly flag the missing async option.

We only have a single .credo.exs config at the root and I replicated the issue with the barebones config:

%{
  configs: [
    %{
      name: "default",
      checks: %{
        enabled: [{Credo.Check.Refactor.PassAsyncInTestCases, []}]
      }
    }
  ]
}

Before this change, inside the Credo.Sources.find_in_dir the value for included_patterns would compile down to:

["/Users/tom/my_umbrella_app/test/**/*_test.exs"]

But that would skip everything that was under my_umbrella_app/apps/**/test

I see this was intentionally changed in ac76775 so maybe I'm wrong to submit this PR and would appreciate feedback! Changing this locally did make the check work from both the root and the individual umbrella app directories though.

Thx for pointing this out. I will take a closer look soon. 👍

Thanks for taking a look!

I've reproduced in a minimal example in this repo: https://github.com/tomasz-tomczyk/credo-async-example

• .credo.exs with the single rule
• test without async option
• CI workflow running mix credo from root (passing) and then the _web directory (failing)

@tomasz-tomczyk I had to change the way the files were addressed, because the check for wrong file extensions would otherwise yield issues for files like lib/foo/foo_case_test.ex which we avoided in the past.

Please check out the RC to see if this works for you: https://github.com/rrrene/credo/releases/tag/v1.7.7-rc.0 👍

Ah okay, got it. Thanks! It works for us yes 👍
