General comment for this and the lists of semver ranges above - what are we testing? Is it validating admission? If so - there are straightforward ways to unit-test that logic that will be orders of magnitude faster than this. Lists such as these look like the wrong level of abstraction to test in integration tests.

This is a direct translation of the existing tests. I'm not looking to change the nature of the tests here.

So, there's a set of validatior tests in a subdirectory of this, to which these can probably be moved.
That's a much smaller translation, so I'd be willing to add these tests to there.

And my recollection is that the complex regex used to validate these semvers may be a bit lenient, so this is a more thorough test.

That appears to be the case, not all of these can be easily validated by the admission validation (see #542 https://github.com/operator-framework/operator-controller/pull/542/files#diff-6af2fcdc11cc7d43e85d42a4926bfa2ffd47e2292b09ba20407ba78b0f34c3d1R74), so these need to be left here, as they are testing the parsing code during reconciliation.

Are you saying we should not test a complex regex? Or are you saying there's a better way to test the regex?

Sorry, missed this - let's keep it for now but open an issue to do it at the unit level. If you follow this code you can see how to generate a validator for a structural schema. Then you can run this a couple orders of magnitude faster and without network hops. I don't think it's good for anyone to run unit-level validations in e2e.

A reminder that this is unit tests. The e2e tests are in #545
