Code review: ✅
These tests look really solid. Thank you for migrating these test cases. Much appreciated.

I have a couple of notes:

• For the deployment controller tests, the Before section has By parts that show up even before providing the Context or the It part. This ends up with an odd ordering of the actions, which makes debugging a bit nasty.
• Some descriptions seem to focus on the end result rather than what actually happens in that test case. We can discuss more about these in a call.

@edif2008 Context, Describe, When is the same suite wrappers (they call them node containers in ginkgo world). And they exist for the same purpose - to organize the different aspects of code that we are testing hierarchically.

There is no restriction on how you should use them (for example it's ok to use Context inside Describe, or By inside Context, or Describe inside Context.)

The one general rule here is that It (subject node) should be inside Context/Describe (node containers).
That article might help to understand what ginkgo does under the hood.
