class ExampleTest {

    @Mock private var subject: ClassToTest?

    @Before
    fun setUp() {
        MockitoAnnotations.initMocks(this)
    }

    @Test
    fun verifyThisCausesThat() {
        // Arrange
        val aValue = 10
        `when`(mockedClass.getValue()).thenReturn(aValue)
        // Act
        val result = subject!!.callFunctionToBeTested(mockedClass)
        // Assert
        verify(mockedClass).getValue()
        verify(mockedClass).someSideEffect()
        assertEquals(aValue, result)
