[英]Spring boot rest api post method with oneToMany relationship
[英]Test the Spring Boot Rest API Post Method
我对Junit完全陌生,我必须为Rest Controller编写Junit测试用例,但我没有从应该从哪里开始。 任何帮助将非常感激。
这是我的Rest Controller类。
@RestController
public class RecognitionController {
private FrameDecoder frameDecoder;
private TagEncoder tagEncoder;
private RecognitionService recognitionService;
@Autowired
public RecognitionController(FrameDecoder frameDecoder, TagEncoder tagEncoder,
RecognitionService recognitionService) {
this.frameDecoder = frameDecoder;
this.tagEncoder = tagEncoder;
this.recognitionService = recognitionService;
}
/**
*
* @param take the input as Json Frame and map the output at api/detection Url.
* @return List of Json tag in the Http response.
*/
@RequestMapping(value = "/api/detection", method = RequestMethod.POST)
public List<JsonTag> analyseframe(@RequestBody JsonFrame frame) {
SimpleFrame simpleFrame = frameDecoder.decodeFrame(frame);
List<OrientedTag> orientedTags = recognitionService.analyseFrame(simpleFrame);
return tagEncoder.encodeTag(orientedTags);
}
}
要测试Rest Controller,您需要:
控制器:
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import java.util.ArrayList;
import java.util.List;
@RestController
@RequestMapping(value = "/Entity")
public class EntityRestController {
private EntityService service;
@RequestMapping(value = "/entity/all", method = RequestMethod.GET)
public List<Entity> findAll() {
List<Entity> models = service.findAll();
return createEntities(models);
}
private List<EntityDTO> createDTOs(List<Entity> models) {
List<EntityDTO> dtos = new ArrayList<>();
for (Entitymodel: models) {
dtos.add(createDTO(model));
}
return dtos;
}
private EntityDTO createDTO(Entity model) {
EntityDTO dto = new EntityDTO();
dto.setId(model.getId());
dto.setDescription(model.getDescription());
dto.setTitle(model.getTitle());
return dto;
}
}
测试例:
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import java.util.Arrays;
import static org.hamcrest.Matchers.*;
import static org.mockito.Mockito.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestContext.class, WebAppContext.class})
@WebAppConfiguration
public class EntityRestControllerTest {
private MockMvc mockMvc;
@Autowired
private EntityService entityServiceMock;
//Add WebApplicationContext field here.
//The setUp() method is omitted.
@Test
public void findAllEntitiesTest() throws Exception {
Entity first = new Entity();
first.setId(1L);
first.setDescription("Lorem ipsum")
first.setTitle("Foo");
Entity second = new Entity();
second.setId(2L);
second.setDescription("Lorem ipsum")
second.setTitle("Bar");
when(entityServiceMock.findAll()).thenReturn(Arrays.asList(first, second));
mockMvc.perform(get("/entity/all"))
.andExpect(status().isOk())
.andExpect(content().contentType(TestUtil.APPLICATION_JSON_UTF8))
.andExpect(jsonPath("$", hasSize(2)))
.andExpect(jsonPath("$[0].id", is(1)))
.andExpect(jsonPath("$[0].description", is("Lorem ipsum")))
.andExpect(jsonPath("$[0].title", is("Foo")))
.andExpect(jsonPath("$[1].id", is(2)))
.andExpect(jsonPath("$[1].description", is("Lorem ipsum")))
.andExpect(jsonPath("$[1].title", is("Bar")));
verify(entityServiceMock, times(1)).findAll();
verifyNoMoreInteractions(entityServiceMock);
}
}
请遵循完整的教程以获取更多详细信息。
___EDIT_1___
我不知道“ thenReturn”方法从何而来
静态方法Mockito.when()
具有以下签名:
public static <T> OngoingStubbing<T> when(T methodCall)
当您模拟某些服务并将其作为参数放入其中when
-它返回IS OngoingStubbing<T>
对象。 所有实现OngoingStubbing<T>
都具有thenReturn(T value)
方法并被调用。
