I have some Scala code that I wish to unit test using ScalaMock:

class CancellationManagerSpec extends FlatSpec with MockFactory {    "Cancelling a shipment" should "check shipment is not already shipped" in {      val manager = mock[CancellationsManager]     (manager.checkStatus _).expects(*, *).returning(true).once()      val request = CancellationRequestedEvent("shipmentNumber")     manager.processCancellation(request)   } } 

The test fails:

[info] - should complete a series of tasks in happy case *** FAILED *** [info]   Unexpected call: <mock-6> CancellationsManager.processCancellation(CancellationRequestedEvent(shipmentNumber)) [info]    [info]   Expected: [info]   inAnyOrder { [info]     <mock-6> CancellationsManager.checkStatus(*, *) once (never called - UNSATISFIED) [info]   } [info]    [info]   Actual: [info]     <mock-6> CancellationsManager.processCancellation(CancellationRequestedEvent(shipmentNumber)) (Option.scala:121) 

I want to test that when I process a cancellation, certain tasks are done. More generally, there are logic such as this that I would like to test:

class SalesOrderShippedProcess {   def execute(salesOrder: SalesOrder): Unit = {     if (doTask1() && doTask2()) {       doTask3()       doTask4()       doTask5()     }   }    def doTask1(): Boolean = ???   def doTask2(): Boolean = ???   def doTask3(): Boolean = ???   def doTask4(): Boolean = ???   def doTask5(): Boolean = ??? } 

Where for some process, I want to check task 3, 4, and 5 are done only if task 1 and 2 is successful, and even if task 3 fails, task 4 and 5 should execute regardless.

What’s the best way to test this? Is it failing because I’m calling a method of the mocked object directly? Do I need to move all the task methods to it’s own class then mock it, which seems a little strange to me just to be able to write test for it.
