I found some.

This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

For more information, refer to the documentation. If you are unsure whether to add the message or not, please ping @exercism/maintainers-admin in a comment. Thank you!

We have to fix the issue in the test runner test discovery script.
And also we should make sure that our tests in the main repository are run under the same conditions as the docker version over in the test-runner.

The pre-commit checks will not let me merge this :D

Exactly, you need to put // clang-format off and on around a long name, e.g.:

TEST_CASE(
    // clang-format off
    "non-numeric, non-space char in the middle with a sum that's divisible by 10 isn't allowed",
    // clang-format on
    "[8b72ad26-c8be-49a2-b99c-bcc3bf631b33]") {
    REQUIRE(false == luhn::valid("59%59"));
}

Agreed, it's not exactly robust.

I think they mostly do, don't they? What exactly is different?

I think I know why I didn't catch this. I ran the test runner on exercises in the build_exercises directly that CMake creates, so that the example solutions are in place. I must have accidentally used an old version there. :( TBH, this build_exercises copy is something that I don't particularly like. I will try to come up with something better.

I can confirm you found them all.

Looks fine now, thanks for the quick help!
