LGTM. I would probably just add the test you've created without deleting the existing one. WDYT?

@pkozlowski-opensource I think it's redundant, it tests the exact same thing, just with more lines of code and unneeded assertions...

CLAs look good, thanks!

@shahata hmm, I still would feel a bit safer having those 2 tests as those are not exactly the same: the one you've deleted don't have status text, do 2 requests. Up to you but since tests are cheep I would prefer to be safe than sorry.
