我有一个看起来像这样的 JUnit 测试 - 它是一个更大的应用程序的一部分。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = { MyTestConfig.class })
public class MyHandlerInterceptorTest {

@Autowired
private RequestMappingHandlerMapping requestMappingHandlerMapping;

@Test
public void myTest() throws Exception {
MockHttpServletRequest request = new MockHttpServletRequest("GET",
"/myrequest");
HandlerExecutionChain handlerExecutionChain = requestMappingHandlerMapping.getHandler(request);
}
}

当我单独运行测试时 - 它运行良好。

当我将其作为其他测试套件的一部分运行时 - 我收到错误

似乎发生的情况是我的测试上下文被其他测试窃取。我想知道如何识别何时发生这种情况并阻止它,或者至少解决它。

这与其他问题不同,因为这是关于识别其他测试,而不是通过解决方法来阻止。

我的问题是:如何识别其他 JUnit 测试何时窃取我的 Spring Root Controller ?

最佳答案

尝试将 @WebAppConfiguration 添加到您的测试类,以便它加载 WebApplicationContext 而不是一般的 ApplicationContext。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = { MyTestConfig.class })
@WebAppConfiguration
public class MyHandlerInterceptorTest {

@Autowired
private RequestMappingHandlerMapping requestMappingHandlerMapping;

@Test
public void myTest() throws Exception {
MockHttpServletRequest request = new MockHttpServletRequest("GET",
"/myrequest");
HandlerExecutionChain handlerExecutionChain = requestMappingHandlerMapping.getHandler(request);
}
}
