我有3个独立的项目,由pom.xml绑定。
主 myapp
文件夹中的pom.xml有模块部分。
<modules>
<module>myapp-dao</module>
<module>myapp-webapp</module>
<module>myapp-configuration</module>
</modules>
里面有3个项目 myapp
文件夹(每个文件夹都有自己的pom.xml)。
myapp-dao
myapp-configuration
myapp-webapp
我正在写一个JUnit测试,为一个 @RestController
课堂上 myapp-webapp
模块(不要担心@Test的内容,它只是一个骨架,当我能够运行测试时,它将被扩展)。
@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
@WebMvcTest(ContentController.class)
public class ContentControllerTest {
@Autowired
private MockMvc mvc;
@MockBean
private ContentService contentService;
@MockBean
private HyperlinkReferenceService hyperlinkReferenceService;
@Test
public void givenEmployees_whenGetEmployees_thenReturnJsonArray() throws Exception {
given(contentService.findContentUsedAsTemplateIn(1, 0)).willReturn(null);
mvc.perform(get("/portal/content/1/references/usedAsTemplateIn").contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isOk()).andExpect(jsonPath("$", hasSize(1)));
}
}
当我试图运行测试时,我得到:
java.lang.IllegalStateException: Failed to load ApplicationContext
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.pro4people.msg.ServletInitializer]; nested exception is java.io.FileNotFoundException: class path resource [myapp.properties] cannot be opened because it does not exist
我已经解决了这个问题,复制了 myapp-configuration/target/myapp.properties
到 myapp-webapp/src/main/test/resources/myapp.properties
这样解决了上面的问题,但是另一个问题就出来了。
java.lang.IllegalStateException: Failed to load ApplicationContext
Description:
Field userRepository in com.company.myapp.service.UserServiceImpl required a bean of type 'com.company.myapp.repository.UserRepository' that could not be found.
Action:
Consider defining a bean of type 'com.company.myapp.repository.UserRepository' in your configuration.
但实际上,我在这个测试中根本没有使用UserRepository,所以我推测是Spring上下文的某个地方出现了问题。应用程序通常是按照 war
并部署到Tomcat上,而且只在其 wared
状态下,一切都正确注入和绑定。
怎样才能省略这个问题?不管我想做什么,测试都是在提升spring上下文,而当我删除了 @WebMvcTest(ContentController.class)
,我明白了。
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.company.myapp.controller.portal.json.ContentControllerTest': Unsatisfied dependency expressed through field 'mvc'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.test.web.servlet.MockMvc' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
这似乎是显而易见的。
在你的控制器测试类之上使用Context配置。 @ContextConfiguration(classes = {ContentController.class})
Below code works for unit test for controller.
@RunWith(MockitoJUnitRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = {ContentController.class})
public class ContentController {
private MockMvc mockMvc;
@InjectMocks
private ContentController contentController;
@Mock
private ContentService contentService;
....
/**
* Configure the mockMvc with Controller.
*/
@Before
public void setup() {
mockMvc = MockMvcBuilders.standaloneSetup(contentController).build();
}
@Test
your test here() {
//use Mockito.when(statement).thenReturn(value);
//rest remain same using mockMVC
mockMvc.perform(...)
}
