ryz*_*man 4 java rest spring-mvc mockito spring-test-mvc
我有一个使用 Spring MVC 运行 REST 服务的应用程序(没有 Spring Boot)。上下文主要是从父母那里加载的。我有一个控制器,我想通过 MockMVC 测试它。
我尝试手动设置本地测试上下文,但这不足以运行测试。我想,应该还有我没有设置的额外豆子。
我的控制器是:
@RestController
public class ProrertyEditorController extends AbstractPropertyEditorController {
@Autowired
protected PropertyEditorService prorertyEditorService;
@RequestMapping(method = RequestMethod.DELETE, value = "/{dataType}/deletewithcontent")
@ResponseStatus(value = HttpStatus.OK)
public void deleteWithContent(@PathVariable("dataType") String dataType, @RequestParam("deleteall") boolean deleteAllContent, @RequestBody String node) {
try {
JSONArray itemsToDelete = new JSONArray(node);
prorertyEditorService.deleteItemsWithContent(dataType, itemsToDelete, deleteAllContent);
} catch (Exception e) {
//handling exception
}
}

到目前为止,控制器的测试如下所示:
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration("classpath*:configBeans1.xml")
public class ProrertyEditorControllerTest{
private MockMvc mockMvc;
@Mock
private PropertyEditorService mockService;
@InjectMocks
private ProrertyEditorController controller;
@Before
public void setup() {
mockMvc = MockMvcBuilders.standaloneSetup(new ProrertyEditorController()).build();
}
@Test
public void deleteWithContentTest() throws Exception {
mockMvc.perform(delete("/full/path/{dataType}/deletewithcontent", type)
.param("deleteall", "true")
.param("node", "[{\"test key1\":\"test value1\"}, {\"test keys2\":\"test value2\"}]"));
verify(mockService, times(1)).deleteItemsWithContent(eq("promotion"), eq(new JSONArray("[{\"test key1\":\"test value1\"}, {\"test keys2\": \"test value2\"}]")), eq(true));
}

不幸的是,它不起作用,因为

并且没有创建任何bean
PS 有一个选项可以使用
MockHttpServletRequest request = new MockHttpServletRequest();
MockHttpServletResponse response = new MockHttpServletResponse();

但是,它需要重构控制器方法,这是不可能的
事实证明,完全有可能做到。启动它只需要一些配置。
您将需要进行弹簧测试pom.xml才能使其正常工作
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<scope>test</scope>
</dependency>

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
</beans>

controllerTest使用以下注释配置您的类:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath*:testContextConfig.xml")
@WebAppConfiguration
public class ControllerTest { ... }
Run Code Online (Sandbox Code Playgroud)我应该提到,没有@ContextConfiguration MockMVC就行不通。
MockMVC在@Before方法中创建一个实例:
private MockMvc mockMvc;
@Mock
private Service mockService;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(new Controller(mockService))
.setHandlerExceptionResolvers(exceptionResolver()) //crutial for standaloneSetup of MockMVC
.build();
}

基本上就是这样。
