Answer 1

Judging by the names of your function calls, yes, you would have to wait. fetch implies that you are performing an ansynchronous (a promise) call for data. That would, most likely, set some form of state. Doing that would rerender something (which takes a moment). Waiting for data changes is one of the hardest bits to wrap your head around when writing testing.
