My third test is failing

@Test public void detail_ShouldErrorOnNotFound() throws Exception { // Arrange the mock behavior when(service.findById(1L)).thenThrow(FavoriteNotFoundException.class);

    // Act (perform the MVC request) and Assert results
    mockMvc.perform(get("/favorite/1"))
        .andExpect(view().name("error"))
            .andExpect(model().attribute("ex", Matchers.instanceOf(FavoriteNotFoundException.class)));
    verify(service).findById(1L);
}
