Question

I thought mockk mocks are strict by default but mockito are not but dont want to go deeper to compare it Not near PC

Mike · Answer

Mockito uses strict to mean a slightly different thing than MockK s usage of strict That s the short answer And in 2 0 Mockito added strictness When you have a chance I documented differences here <http mikewilkes ca 2018 06 23 kotlin testing with mocks > Mockito gt gt gt Using Mockito Extension in JUnit Jupiter and annotation based mocking results in strict checking Basically if no expectations are defined on a mock object it will act like a stub This means it will return a reasonable default for any calls As soon as an expectation is defined the Mock becomes strict It will report any calls that don t match a defined expectation AND will report any expectations that were defined but not called This is like defining verify on every interaction and adding a verify no more interactions There is no option to ensure a mock is actually used as a mock until at least one interaction is defined The only way to ensure all mock calls are defined would be to call verify with noMoreInteractions on all mocks at the end of the test

That s a bit different from MockK s definition

< oleksiyp> is there any plans to have something like this in Mockk

Mike · Answer

If you re looking at mockk then this isn t truly relevant I ve discovered that JUNIT or Mockito has been fixed so that the JUNIT extension works using mock now Need to update post hut haven t yet

seems I need to migrate to Mockito from Mockk

Mike · Answer

Depends on what you want Mockk definitely has some features Mockito doesn t and it s a little more fluid in its definitions And Mockk s strict provides some value that Mockito s doesn t If you define a mock in Mockk as strict and something calls that mock without an explicit definition Mockk will fail Mockito will return default value for call regardless and only reports mock expectations defined but not called during this test run For me I d like both of those covered under strict mocks but it s not for everyone

Can you please drop a ticket You need automatic check Or caliing something alike `everythingUsed` at the end is ok

oleksiyp · Answer

Just one line of exactly what you need dont need to be very descriptive

oleksiyp · Answer

Because I belive mockito doing some hacks to check if all stubbed calls are used
