Fail when a mock is called outside of exhaustive verify

[Cedrick84]

Hi all,

I am new to Mokkery and like the ease of use so far!

To make my tests really strict I would like to achieve the following.
Consider the following code.

val firstMock = mock<FirstDependency>
val secondMock = mock<SecondDependency> 

val sut = SUT(firstMock, secondMock)
sut.methodThatCallsBothMocks()

verify(exhaustive) { 
  firstMock.method()
}

Even though I call a method that invokes first and second mock, the test passes. I expect it to fail as a second dependency is called but this method is not being verified. Is there any way to achieve this behaviour?

Many thanks!

Hi! verify only includes mocks that are invoked inside its block. To verify that some mocks were not called at all you can use verifyNoMoreCalls.

This does work, however now I need to explicitly invoke verifyNoMoreCalls on all my dependencies. In my production code I have a lot more dependencies than this. It is also easy to miss adding a verifyNoMoreCalls to each of the test cases of a specific SUT.
I am looking for a solution where anything missed in the verify block causes a failure, instead of explicitly verifying everything.

I know what you mean. However, implementing this check automatically is problematic. For a reference, Mockk acts the same in given scenario. Maybe with compiler plugin capabilities it could be possible, but it's not easy to do and probably error-prone.
Also, you can eliminate partially the boilerplate with AfterTest:

@AfterTest
fun after() {
   verifyNoMoreCalls(dep1, dep2, dep3)
}

Thank you so much @lupuuss , I will follow that advice for now!
