StepVerifier provides a declarative way of creating a verifiable script for an async Publisher sequence by expressing expectations about the events that will happen upon subscription.

TestPublisher is a publisher that you can directly manipulate, triggering onNext, onComplete, and onError events, for testing purposes.

@DataMongoTest
@ExtendWith(SpringExtension.class)
public class UserRepositoryTest {

    @Autowired
    private UserRepository repository;

    @Test
    public void shouldSaveSingleUser() {
        User user = User.builder()
                .firstName("firstName")
                .lastName("lastName")
                .phone("phone")
                .email("test@gmail.com")
                .role(UserRoles.ADMIN)
                .password("password")
                .active(false)
                .build();
        Publisher<User> setup = repository.deleteAll().thenMany(repository.save(user));
        StepVerifier
                .create(setup)
                .expectNextCount(1)
                .verifyComplete();
    }

    @Test
    public void shouldSaveUser() {
        String TEST_EMAIL = "test@gmail.com";
        User user = User.builder()
                .firstName("firstName")
                .lastName("lastName")
                .phone("phone")
                .email(TEST_EMAIL)
                .role(UserRoles.ADMIN)
                .password("password")
                .active(false)
                .build();
        Publisher<User> setup = repository.deleteAll().then(repository.save(user));
        Mono<User> find = repository.findUserByEmail(TEST_EMAIL);
        Publisher<User> composite = Mono
                .from(setup)
                .then(find);
        StepVerifier
                .create(composite)
                .consumeNextWith(account -> {
                    assertNotNull(account.getId());
                    assertEquals(account.getEmail(), TEST_EMAIL);
                    assertEquals(account.getFirstName(), "firstName");
                    assertEquals(account.getLastName(), "lastName");
                })
                .verifyComplete();
    }
}
