Your system is ready to brew.

Verification

• My "brew doctor output" above says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update twice and am still able to reproduce my issue.
• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.

What were you trying to do (and why)?

I was running brew tests. Was just curious what it does, after seeing it mentioned under How to Open a Pull Request - Create your pull request from a new branch. I also wanted to use it as a way to test if any changes I make in the near future introduce breakage.

What happened (include all command output)?

Also mentioned in #15635.

The message brew tests expected is in https://github.com/Homebrew/brew/blob/master/Library/Homebrew/caveats.rb#L58.

Is there a way to run only a specific test from brew tests?

[carlocab]

Is there a way to run only a specific test from brew tests?

From brew help tests:

❯ brew help tests
Usage: brew tests [options]

Run Homebrew's unit and integration tests.

[snip]

      --only                       Run only test_script_spec.rb. Appending
                                   :line_number will start at a specific
                                   line

You only get file-level granularity of test selection, though.

Not sure which step in Homebrew's Dockerfile handles this.

[MikeMcQuaid]

Happy to keep helping in this issue but closing because it's working in our CI.

[osalbahr]

@MikeMcQuaid Are you able to replicate this error locally? So far the test seems to only reliably pass on macOS.

Also, since the issue is closed now, would you suggest I open a discussion at https://github.com/orgs/Homebrew/discussions ?

[MikeMcQuaid]

@osalbahr I cannot replicate locally and this test is passing in multiple configurations in the Linux CI on this repository.

[Bo98]

In the Linux case, I believe it happens if systemctl is not available. The test should ideally mock pretending that it is available.

[osalbahr]

I think it has to do with the way brew config works perhaps? (as in #15689). Does brew tests use a similar mechanism to brew config to determine the OS type? I think the tests --only caveats passing depends on whether tests knows that I'm not on a macOS.

I see two ways going about this:

1. Include lsb-release in homebrew/brew (20.8 MB of additional disk space, and consequently a few more seconds in CI). This is probably not worth it.
2. Wait until linux.rb falls back to $HOMEBREW_OS_VERSION ($PRETTY_NAME) before going to Unknown and see if that fixes it. I think it probably will, I will see.

My goal is that brew tests should pass off the bat when the requirements in "Homebrew on Linux" are satisfied (in a best-effort manner). Earlier I'd just ignore brew tests if I don't think the error is relevant, which is not ideal.

[osalbahr]

In the Linux case, I believe it happens if systemctl is not available. The test should ideally mock pretending that it is available.

I'm not sure if this is the case, at least not in podman run -it homebrew/brew on my machine. I also accidentally discovered that redirecting the output of brew tests --only caveats to tee, or tail, breaks it, but not cat? I have no idea why. Anyways, lsb_release is needed regardless of the redirection.

I thought containers were meant to be reproducible, and they are for the most part, but I guess not perfectly. It seems to depend on the host, or maybe whether I use podman or docker (I'd have to cross-check my dual-boot of macOS and Fedora Silverblue. The tests above were using podman on Silverblue):

Ok, it seems to sometimes pass even without lsb_release, but maybe less often. I'm confused.
