Java jUnit@beforeAll不工作
我正在为RESTAPI spring boot编写单元测试Java jUnit@beforeAll不工作,java,junit,Java,Junit,我正在为RESTAPI spring boot编写单元测试 @RunWith(SpringRunner.class) @SpringBootTest(classes = WorkflowEngineApiApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class ActionControllerTest { @LocalServerPort public i
@RunWith(SpringRunner.class)
@SpringBootTest(classes = WorkflowEngineApiApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ActionControllerTest {
@LocalServerPort
public int port;
private final TestRestTemplate testRestTemplate = new TestRestTemplate();
private final HttpHeaders headers = new HttpHeaders();
private long actionId;
@BeforeClass
public static void init() throws Exception{
String url="/api/v1/actions";
JSONObject action = new JSONObject();
action.put("name", "Name Test");
action.put("actionTypeId", 4L);
action.put("description", null);
action.put("createdBy", 2L);
action.put("processId", 2L);
headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
ResponseEntity<ApiResponse> response = getResponse(url, HttpMethod.POST, action.toString());
}
private static ResponseEntity<ApiResponse> getResponse(String url, HttpMethod method, Object action){
HttpEntity<Object> entity = new HttpEntity<>(action, headers);
return testRestTemplate.exchange(createURL(url), method, entity, ApiResponse.class);
}
/**
* create url http://localhost:...
* @param uri String
* @return String
*/
public static String createURL(String uri) {
return "http://localhost:" + port + uri;
}
}
我想在测试运行之前向Db添加1行。但当我将@BeforeClass与静态方法一起使用时,端口变量必须是静态的,但它不会生成值。还是0。
错误显示:
org.springframework.web.client.ResourceAccessException:上的I/O错误
邮寄申请
我的问题:有没有办法将@BeforeClass与webEnvironment=SpringBootTest.webEnvironment.RANDOM_PORT一起使用,这意味着@LocalServerPort使用静态生成值

所以,我的理解是,你们想写下从控制器到数据库的集成测试。这是我的建议
@RunWith(SpringRunner.class)
@SpringBootTest
@WebAppConfiguration
@Transactional
public class MyIntTest {
private MockMvc mockMvc;
@Autowired
private WebApplicationContext ctx;
@Before
public void setUp() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
MockHttpServletRequestBuilder builder = MockMvcRequestBuilders.post(**Your URL").accept(MediaType.APPLICATION_JSON)
.contentType(MediaType.APPLICATION_JSON);
builder.setContent("Your JSON request data");
// This will invoke POST request to "URL"
this.mockMvc.perform(builder);
// If you want to verify your result
MvcResult result = this.mockMvc.perform(builder).andReturn();
// Read response. If its custom class then just change return type.
List responses = getPojoFromMvcResult(result, List.class);
}
public static <T> T getPojoFromMvcResult(MvcResult result, Class<T> valueType) throws IOException {
try {
MockHttpServletResponse response = result.getResponse();
String responseJson = response.getContentAsString();
return convertJsonToObject(responseJson, valueType);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
public static <T> T convertJsonToObject(String content, Class<T> valueType) throws IOException {
return new ObjectMapper().readValue(content, valueType);
}
}
但我想直接调用api进行测试。所以我需要在所有测试运行之前添加测试记录!this.mockMvc=MockMvcBuilders.webAppContextSetupctx.build;MockHttpServletRequestBuilder=MockMvcRequestBuilders.post**您的URL.acceptMediaType.APPLICATION\u JSON.contentTypeMediaType.APPLICATION\u JSON;builder.setContentYourJSON请求数据;//这将调用POST请求以URL This.mockMvc.performbuilder;以上代码将调用POST并为您创建数据。
