Learn how to use MockK by seeing equivalents to functions in Mockito.

Create a mock

The similarities and differences in creating mocks between Mockito and MockK.

`when` and `do*`

when(x).thenReturn(y), doReturn, and more.

`eq`

Mockito’s eq, refEq, and same argument matchers.

`any*`

The “any” family of matchers: any, anyBoolean, anyByte, anyChar, anyDouble, anyFloat, anyInt, anyLong, anyObject, anyShort, and anyString.

`verify`

verify that a method was called.

`argThat`

Porting custom matchers with argThat

`ArgumentCaptor`

Capturing arguments to check them later.

`void` methods

MockK makes it easier to mock methods that return void.
