                       I reload the entity from the database using the repository to be sure these columns are not null. I set them to null, save the entity, and load it back from the database. Now both columns are indeed null, which is what I've been expecting.

                      How to mock repository Spring

                      Asked 2022-Jan-25 at 05:16

                      My test class looks this way and I try to mock repository to return list of real objects.

                      In debug, I see that hashes of mock repository and service's repository during test are the same. Nonetheless I anyway receive empty ArrayList.

                      None of the previous answers like this or this etc. helped me.

                      Looks like you should use @MockBean not @Mock in test class.

                      MockBean is used to add mocks to a Spring ApplicationContext, not only "mock" an real object.
