如何为Spring Boot Controller端点编写单元测试
如何为Spring Boot Controller端点编写单元测试
提问于 2015-03-15 04:43:40
我有一个示例Spring Boot应用程序，其中包含以下内容
引导主类
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}控制器
@RestController
@EnableAutoConfiguration
public class HelloWorld {
@RequestMapping("/")
String gethelloWorld() {
return "Hello World!";
}
}为控制器编写单元测试的最简单方法是什么？我尝试了下面的方法，但它抱怨未能自动连接WebApplicationContext
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = DemoApplication.class)
public class DemoApplicationTests {
final String BASE_URL = "http://localhost:8080/";
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void testSayHelloWorld() throws Exception{
this.mockMvc.perform(get("/")
.accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
.andExpect(status().isOk())
.andExpect(content().contentType("application/json"));
}
@Test
public void contextLoads() {
}

Spring Boot 1.4.M2中首次亮相的新测试改进可以帮助您减少编写此类情况所需的代码量。
测试将如下所示：
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
@RunWith(SpringRunner.class)
@WebMvcTest(HelloWorld.class)
public class UserVehicleControllerTests {
@Autowired
private MockMvc mockMvc;
@Test
public void testSayHelloWorld() throws Exception {
this.mockMvc.perform(get("/").accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
.andExpect(status().isOk())
.andExpect(content().contentType("application/json"));
}

这里是使用Spring MVC的standaloneSetup的另一个答案。使用这种方法，您可以自动连接控制器类或对其进行模拟。
import static org.mockito.Mockito.mock;
import static org.springframework.test.web.server.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.server.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.server.result.MockMvcResultMatchers.status;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.web.server.MockMvc;
import org.springframework.test.web.server.setup.MockMvcBuilders;
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class DemoApplicationTests {
final String BASE_URL = "http://localhost:8080/";
@Autowired
private HelloWorld controllerToTest;
private MockMvc mockMvc;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.standaloneSetup(controllerToTest).build();
}
@Test
public void testSayHelloWorld() throws Exception{
//Mocking Controller
controllerToTest = mock(HelloWorld.class);
this.mockMvc.perform(get("/")
.accept(MediaType.parseMediaType("application/json;charset=UTF-8")))
.andExpect(status().isOk())
.andExpect(content().mimeType(MediaType.APPLICATION_JSON));
}
@Test
public void contextLoads() {
}

向您的DemoApplicationTests类添加@WebAppConfiguration (org.springframework.test.context.web.WebAppConfiguration)注释将会起作用。
