Make sleep time based tests more robust and faster

[Pijukatel]

Quite a lot tests in our code base have pattern like this:

action

sleep(sleep_time)

assert expectation

Such test can be flaky when sleep time is not large enough or will take a lot of time, when sleep time is too big.
It can be advantageous to create a helper function that makes such test more robust in worst case scenario and faster in best case scenario.

action

assert expectation_met_within_deadline(expectation, check_period, check_deadline)

where check_period is very low number and check_deadline is larger number.

Non abstracted version of this pattern was used here for example:

Create such abstracted helper function and apply it across the codebase tests.
