This obviously matches the original, but it doesn't necessarily prove that we have actually correctly matched the suite-with-hyphens suite name.

Particularly since we don't appear to have any coverage that it fails with an error if you specify a suite name that does not exist. We could theoretically be falling back to the first / default / all suites in this situation (we're not, but that could change in the future).

I think it might actually be viable to just rename the second suite in the existing behat-two-features.php config file to suite-with-hyphens and just reuse those examples to prove that we've selected the correct features to run. I don't think any of the other scenarios here depend on the naming of that suite.

Equally, these are quite minor/theoretical concerns so feel free to ignore & move on!

Yeah, I see what you mean. I modified the configuration for this suite so that it actually runs some tests and then confirmed that they were run
