Is this BeforeEach that's nested in the first Context container (lines 53-55) still relevant now:

		BeforeEach(func() {
			By("using the default OperatorGroup created in BeforeSuite")
		})

It looks like there's a test case that creates a failing CSV without an explicit metadata.Namespace but I think that's fine as the test case does properly cleanup that CSV afterwards.

Ran this locally and didn't see any obvious resource leakage:

$ gh pr checkout 2716
$ kind create cluster ; make run-local
$ make e2e E2E_INSTALL_NS=olm TEST="Metrics are generated for OLM managed resources" 
$  k get ns
