我正在尝试使用 TDD.我正在尝试使用 Mockito 结合 MockMvc 和 Junit 为控制器编写单元测试用例.
I am trying to get my feet wet with TDD. I am trying to write unit test cases for controllers using Mockito in conjunction with MockMvc and Junit.
但是我遇到了运行时错误,因此我的测试失败了.起初,由于找不到 javax.servlet.SessionCookieConfig
失败,我在设置中初始化 MockMvc 实例时遇到了问题.
But I am getting a runtime error thereby failing my test. At first I was facing problem in initializing the MockMvc instance in the setup due to failure in finding the javax.servlet.SessionCookieConfig
.
我通过下载 javax.servlet
api 并将其配置到项目的构建路径中解决了这个问题,但随后我面临
This I resolved by downloading the javax.servlet
api and configuring it into the build path of the project but then I am facing the
java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.isAsyncStarted()
在 MockMvc 实例上使用 perform()
时.
while using perform()
on the MockMvc instance.
谁能告诉我如何处理这种依赖关系,因为我认为这是由于服务器 servlet-api 和 javax.servlet api 不兼容而发生的.
Can anyone tell me what to do with this kind of dependencies as I think it is occurring due to the incompatible server servlet-api and javax.servlet api.
我正在发布我用于单元测试的代码,但我认为这不会有任何帮助,但以防万一:
EDIT : I am posting the code I am using using for unit testing but I don't think it would be any help but just in case :
@RunWith(MockitoJUnitRunner.class)
public class MyControllerTest {
@InjectMocks
private MyController myController = new MyController();
@Mock
private MyService myService = new MyServiceImpl();
private MockMvc mockMvc;
@Before
public void setUp(){
this.mockMvc = MockMvcBuilders.standaloneSetup(myController).build();
}
@Test
public void testList() throws Exception{
A a = new A();
a = createMockClassA();
Mockito.when(myService.getServiceForA(Mockito.anyMapOf(String.class, String.class))).thenReturn(a);
MvcResult result = this.mockMvc.perform(get("/somePath/")).param("someExpectedParam","value").andReturn();
System.out.println(result.getResponse().getContentAsString());
}
private static A createMockClassA(){
A a = new A();
a.setId(i);
a.setTitle("mock-" + i);
return a;
}
}
这听起来很像您在类路径中的 servlet API 版本错误.
This sounds very much like you have the wrong version of the servlet API in the class path.
检查何时将 isAsyncStarted
添加到 API,并确保您在类路径中引用的版本至少是该版本或更高版本.
Check when isAsyncStarted
was added to the API and make sure the one you reference in your classpath is at least that version or higher.
为了找到错误"类版本来自的位置,您可以使用
In order to find the location where the 'wrong' class version is comming from you can use the
-verbose:class
java 的参数.它将列出所有加载的类,如果我没记错的话,它们是从哪里加载的.请参阅 http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html了解详情.
Argument for java. It will list all the classes loaded and if I remember correctly whery they get loaded from. See http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html for details.
