[英]Spring Boot - Junit unable to load configuration properties in junit test
[英]Unable to create JUnit Test for Spring Boot Controller
我正在嘗試為 SpringBoot 應用程序中的簡單控制器編寫測試。 但是,由於我的 TopicRepository 和 TopicController 的 bean 創建,我收到了錯誤。 我參考了一個教程,對 Spring Boot 開發並不陌生,所以不確定它是如何工作的。 我怎樣才能使測試工作?
控制器測試
@RunWith(SpringRunner.class)
@WebMvcTest(TopicController.class)
public class TopicControllerTest {
@Autowired
private MockMvc mvc;
@MockBean
private TopicService topicService;
@Test
public void whenGetTopics_returnJSONArray()
throws Exception {
Topic topic = new Topic("b","b name", "b descp");
List<Topic> allTopics = new ArrayList<>();
allTopics.add(topic);
Mockito.when(topicService.getAllTopics()).thenReturn(allTopics);
mvc.perform(get("/topics")
.contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(jsonPath("$[0].id", is(topic.getId())));
}
}
控制器
@RestController
public class TopicController {
@Autowired
private TopicService topicService; //inject the topicService as a dependency
@Autowired
private TopicRepository topicRepository;
@RequestMapping("/topics")
public List<Topic> getAllTopics() {
return topicService.getAllTopics();
}
@RequestMapping("/topics/{name}")
public Topic getTopic(@PathVariable String name) {
return topicService.getTopic(name);
}
@RequestMapping(method=RequestMethod.POST, value= "/topics")
public void addTopic(@RequestBody Topic topic) {
topicService.addTopic(topic);
}
@RequestMapping(method=RequestMethod.PUT, value = "/topics/{Id}")
public void updateTopic(@RequestBody Topic topic, @PathVariable String Id){
topicService.updateTopic(topic, Id);
}
}
主題庫
public interface TopicRepository extends CrudRepository<Topic, String>{
}
我得到的錯誤是
UnsatisfiedDependencyException:創建名為“topicController”的 bean 時出錯:通過字段“topicRepository”表達的不滿意依賴; 嵌套異常是 org.springframework.beans.factory.NoSuchBeanDefinitionException:沒有可用的“io.nkamanoo.springbootstarter.repository.TopicRepository”類型的合格 bean:預計至少有 1 個 bean 有資格作為自動裝配候選。 依賴注解:{@org.springframework.beans.factory.annotation.Autowired(required=true)}
您需要使用@SpringBootTest注釋您的測試類,以便它創建所有定義的 bean 並啟動您的應用程序以運行測試用例。
在您的代碼中:
@RunWith(SpringRunner.class)
@WebMvcTest(TopicController.class)
@SpringBootTest
public class TopicControllerTest {
}
