java.lang.IllegalArgumentException：需要WebApplicationContext

Question

黄瓜档案是::

@RunWith(Cucumber.class)public class runTest {}

SpringRunner File ::

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class, properties = "spring.main.web-application-type=reactive",webEnvironment = WebEnvironment.RANDOM_PORT)
@WebAppConfiguration
@AutoConfigureMockMvc
@ContextConfiguration
public abstract class SpringIntegrationTesting {}

步骤定义文件::

@ContextConfiguration(locations = { "Cucumber.xml" })
@WebAppConfiguration
public class UserLoginSteps extends SpringIntegrationTesting {

    @Autowired
    private WebApplicationContext wac;
    private MockMvc mvc;
    private MvcResult result;
    @Inject
    public void init(WebApplicationContext context) {
        this.wac = context;
    }
    @Before
    public void before() throws Exception {
        mvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }
....}

错误是

使用黄瓜和SpringRunner自动测试spring boot api使用feature文件，其中run run test class的测试开始使用junit测试它崩溃并给出上述错误
