Test that trigger is not ready before dependency exists with dependency annotation

[Cali0707]

Problem
Currently in the rekt test TestTriggerDependencyAnnotation, we do not verify that the trigger is not ready until the PingSource exists. A simple way to fix this would be to move the trigger.IsReady(...) call from the Setup phase to the Requirement phase, and then add a new step function to the Setup phase which checks that the trigger is not ready with reason DependencyDoesNotExist.

Persona:
Which persona is this feature for?

Exit Criteria
The rekt test verifies that the trigger is not ready with reason DependencyDoesNotExist before the PingSource is installed.

Time Estimate (optional):
How many developer-days do you think this may take to resolve? 1

@Cali0707 we have to change all the trigger.IsReady(...) setup phase to requirement phase?

[Cali0707]

hey @Rahul-Kumar-prog , you only need to move the trigger.IsReady(..) to the requirement phase for the specific test feature that I linked above. All other tests should be left unchanged.

You will also need to add the step function I was mentioning above that verifies that the trigger is not ready with reason DependencyDoesNotExist to the setup phase for the test I linked above

@Cali0707
here DependencyDoesNotExist, is it a function or string.
because in setup phase it only takes a string and a featur.Stepfn? can you tell me about this?

And when I write trigger.---- there no any dependencydoesnotexist.
If so should I handle it with err?

I'd recommend reading the documentation in https://github.com/knative-extensions/reconciler-test/ which I linked above, this explains how the e2e tests and phases work

here DependencyDoesNotExist, is it a function or string.
You will need to create a function which checks for this status reason (which will be a string). This is where the StepFn comes in
