@ExtendWith(MockitoExtension.class)

  private MockMvc mockMvc;

  @InjectMocks
  private ApiRestController apiRestController;

  @BeforeEach
  void setUp() {
    mockMvc = MockMvcBuilders
        .standaloneSetup(apiRestController)
        .build();
  }

  @Test
  void shouldReturnsVersion() throws Exception {
    mockMvc.perform(get("/api/v1/version"))
        .andExpect(status().isOk())
        .andExpect(content().contentType(MediaType.APPLICATION_JSON))
        .andExpect(content().json(OBJECT_MAPPER.writeValueAsString(new VersionResponse(VERSION))));
  }
} 

我收到一个错误：

  private static final ObjectMapper OBJECT_MAPPER = new ObjectMapper();
  private MockMvc mockMvc;

  @InjectMocks

  @BeforeEach

    mockMvc = MockMvcBuilders
        .standaloneSetup(apiRestController)
        .build();
  }

  @Test
  void shouldReturnsVersion() throws Exception {
    mockMvc.perform(get("/api/v1/version")) …
