MongoDB存储库的MockBean-只保存生成描述的结果，其他mock方法返回null

Question

我正在测试一个具有MongoDB ReactiveMongoRepository回购依赖项的服务。我正在使用@mockbean来注入mock存储库。4个中只有1个定义when（）.thenreturn（）工作，其余的在运行单元测试时生成null。代码如下：

    @Autowired
private BlogpostServicePersist testee;

@MockBean
private BlogpostRepository repo;
private Class<BlogpostMongoDoc> entityClass = BlogpostMongoDoc.class;
private String testId1 = "save 01 ID";
private BlogpostMongoDoc postMongoDOc = (BlogpostMongoDoc) initialize(
        BlogpostMongoDoc.newInstance(testId1, "save 01 title", "save 01 text", "save 01 author"));;
private BlogpostDTO postDTO = (BlogpostDTO) initialize(
        BlogpostDTO.newInstance(testId1, "save 01 title", "save 01 text", "save 01 author"));

@BeforeAll
void setup() {
    when(repo.save(any(entityClass))).thenReturn(just(postMongoDOc));
    when(repo.deleteById(anyString())).thenReturn(Mono.empty().then());
    when(repo.findById(eq(testId1))).thenReturn(just(postMongoDOc));
    when(repo.findAll()).thenReturn(Flux.just(postMongoDOc, postMongoDOc));
}

@Test
void testSave() {
    create(testee.save(postDTO)).expectNextMatches(this::matchPost).expectComplete().verify();
}

@Test
void testGetStream() {
    create(testee.getAll()).expectNextMatches(this::matchPost).expectNextMatches(this::matchPost).expectComplete()
            .verify();
}

@Test
void testDelete() {
    create(testee.delete(testId1)).expectComplete().verify();
}

@Test
void testGetByID() {
    create(testee.getByID(testId1)).expectNextMatches(this::matchPost).expectComplete().verify();
}

testSave工作正常。以下是服务代码：

    @Override
public Mono<BlogpostDTO> save(BlogpostDTO newPost) {
    return repo.save(toEntity(newPost)).map(this::toDTO);
}

    @Override
public Mono<BlogpostDTO> getByID(String id) {
    return repo.findById(id).map(this::toDTO);
}

当定义从前面移动到测试方法时也是如此：

    @Test
void testGetStream() {
    when(repo.findAll()).thenReturn(Flux.just(postMongoDOc, postMongoDOc));
    create(testee.getAll()).expectNextMatches(this::matchPost).expectNextMatches(this::matchPost).expectComplete()
            .verify();
    verify(repo).findAll();
}
