Mockk: equivalent of verifyNoMoreInteractions() ?

[carlomorelli]

Hi all, I'm converting many tests in Kotlin + Mockk and I wonder how to run the equivalent of verifyNoMoreInteractions() from Mockito?

I can do verifyZeroInteractions() with verify(exactly=0) { .. } but for the other one I don't see a way.

Any help ;) ?

Hi. Let me check

[oleksiyp]

May be

verify { listOf(mock1, mock2) wasNot Called }

is what you are searching for

[oleksiyp]

Dont need to be list, just one mock can be as well

[LeoColman]

One point to add to this is that verifyZeroInteractions should count for all other interactions

So

val mocked = mock()

every { mocked.x } returns y
//Something happens

verify(exactly = 3) { mocked.x }

//Other methods are called, and I want to make sure mocked.x wasn't called anymore
verify(exactly = 0) { mocked.x }

At least this is mockito's behaviour, not sure if this is expected from Mockk, just commented for clarification

Hi @oleksiyp , just tried this:

every { mock.method(any()) } returns res
...
verify { mock.method(any) }
verify { mock.method wasNot Called }

the second verify makes the test fail.
My workaround is to force the verification with the hit time specified:

verify(exactly =1 )  { mock.method(any) }

but in this way subsequent refactorying of the called code I could change the invokations to 2 instead of 1 and this would break the test.

Correct usage is:

verify { mock wasNot Called }

[carlomorelli]

yes sorry i was doing the correct one already, it was just a typo in this comment.
I guess that verify { mock wasNot Called } is actually the equivalent of Mockito.verifyZeroInteracitons()

[oleksiyp]

Kind of. It is only chrcking for specified mocks, but doing more than that looks not very right thing

[oleksiyp]

Looks like resolved

Update: In case anyone tries to use verify { mock wasNot Called } to replace verifyZeroInteractions() but couldn't pass the test. The correct usage is confirmVerified(mock). See "Verification confirmation" section in https://mockk.io/
