I deleted the test I made because I found it unnecessary and it wasn't working well in the CI. However, it passes when I run it locally (A classic)

I don't understand why the kuttl/harness/1-036_validate_role_rolebinding_for_source_namespace test sometimes passes and sometimes doesn't, even though I haven't changed any code. For example, in the last commit, I deleted a test I created, and it didn't pass, but in the previous two commits, it did pass.

Hi @enriqueav99,

kuttl/harness/1-036_validate_role_rolebinding_for_source_namespace

is a known flaky test. You can ignore it.
