Getting an UnfinishedStubbingException with void method

[Rodrigo]

Hi all

I'm using Mockito and I'm getting an UnfinishedStubbingException when I try to run my Junit test but I did not discover the reason why yet... Do you guys know what can be the reason of this exception?

Here is the code:

Thanks!

This is the code:

    Invoker invoker = mock(Invoker.class);

    HttpServletRequest httpServletRequest = mock(HttpServletRequest.class);

    Abcd abcd = mock(Abcd.class);

    MyRepository myRepository = mock(MyRepository.class);

    @BeforeEach

    void before(PactVerificationContext context) {

        doAnswer((invocation) -> {

                    XptoClassOutputBoundary test = invocation.getArgumentAt(1, XptoClassOutputBoundary.class);

                    test.getResponse().setValue(new BigDecimal("500"));

                    return null;

                }

        ).when(myRepository).execute(any(), any());
