Using runBlockingTest

Defining where to use runBlockingTest

• We use runBlockingTest to test co-routines that start with launch and async.
• We use this to test the suspend functions

Testing regular suspend functions

• Usually the co-routines involve delay so simulating this in a test is essential since it is different than normal functions that we test.
• Any calls to the delay will automatically advance virtual time by the amount of delay
