如何解决如何编写用于网关云过滤器的junit5测试以及如何获得此代码的完整代码覆盖率
我想为网关云过滤器编写junit测试，但是问题是我是单元测试的新手。请帮我。这是一种私有的授权方法。
[如果没有人知道如何编写spring网关云过滤器，请通过我的网关过滤器方法进行操作。和逻辑]
@Component
@Slf4j
public class AuthorizationFilter extends AbstractGatewayFilterFactory<AuthorizationFilter.Config> {
@Value("${rest.auth.service.url}")
private String authServiceUrl;
@Autowired
RestTemplate restTemplate;
public AuthorizationFilter() {
super(Config.class);
}
private Mono<Void> onError(ServerWebExchange exchange,String err,HttpStatus httpStatus) {
ServerHttpResponse response = exchange.getResponse();
response.setStatusCode(httpStatus);
return response.setComplete();
}
//Here is my authorization details
private UserRoleDetailsDTO getAuthorizationDetails(String authorizationHeader) {
try {
log.error("Checking authorization");
HttpEntity<?> entity = new HttpEntity(null,new HttpHeaders() {{
add("Authorization",authorizationHeader);
add("Accept","application/json");
}});
ResponseEntity<Map> responseMap = restTemplate.exchange(authServiceUrl.concat("/v1/profile"),HttpMethod.GET,entity,Map.class);
System.out.println(responseMap);
if (responseMap.getBody() == null)
log.warn("Received null body in response. Request will end now");
Map data = (Map) responseMap.getBody().get("data");
boolean isAuthorized = data.get("authorized") == null || (boolean) data.get("authorized");
UserRoleDetailsDTO userRoleDetailsDTO = UserRoleDetailsDTO.builder().userId(String.valueOf(data.get("userId"))).
roles((List<RoleDTO>) data.get("roles")).isAuthorized(isAuthorized).build();
return userRoleDetailsDTO;
} catch (RestClientException e) {
String errorResponse = null;
if (e instanceof HttpClientErrorException) {
HttpClientErrorException exception = (HttpClientErrorException) e;
errorResponse = exception.getResponseBodyAsString();
} else errorResponse = e.getMessage();
log.error("error with http connect with error response : {} : {}",errorResponse,e);
return null;
} catch (Exception e) {
log.error("error with http connect : {}",e);
return null;
}
}
// Here is my Gateway filter
@Override
public GatewayFilter apply(Config config) {
return (exchange,chain) -> {
ServerHttpRequest request = exchange.getRequest();
String requestId;
if (request.getHeaders().containsKey("Request-Id")) {
requestId = request.getHeaders().get("Request-Id").get(0);
} else {
requestId = UUID.randomUUID().toString();
log.debug("Request Id not passed. {} is genertaing requestId {}",AuthorizationFilter.class.getSimpleName(),requestId);
}
MDC.put("requestId",requestId);
request.mutate().header("Request-Id",requestId);
if (!request.getHeaders().containsKey("Authorization")) {
log.error("No authorization header");
return onError(exchange,"No Authorization header",HttpStatus.UNAUTHORIZED);
}
String authorizationHeader = request.getHeaders().get("Authorization").get(0);
UserRoleDetailsDTO userRoleDetailsDTO = getAuthorizationDetails(authorizationHeader);
if (userRoleDetailsDTO == null || !userRoleDetailsDTO.isAuthorized()) {
log.error("Invalid authorization header");
return onError(exchange,"Invalid Authorization header",HttpStatus.UNAUTHORIZED);
}
String userDetailsStr = "";
try {
userDetailsStr = new ObjectMapper().writeValueAsString(userRoleDetailsDTO);
System.out.println("value 1 :"+userDetailsStr);
} catch (JsonProcessingException e) {
log.error("Exception writing user details to string. ",e);
}
if (StringUtils.isEmpty(userDetailsStr))
log.warn("Empty User Details string being passed!!");
request.mutate().header(ApplicationConstants.USER_DETAILS_HEADER,userDetailsStr);
System.out.println("value 2 :"+request.mutate().header(ApplicationConstants.USER_DETAILS_HEADER,userDetailsStr));
return chain.filter(exchange.mutate().request(request).build());
};
}
@Override
public Config newConfig() {
return new Config();
}
public static class Config {
// Put the configuration properties
}
}
这是我的用户角色详细信息
public class UserRoleDetailsDTO {
private String userId;
private List<RoleDTO> roles;
private boolean isAuthorized = true;
}
和RoleDto类
public class RoleDTO {
private String name;
private int weight;
}
这是我在进行代码覆盖率测试时进行的junit测试，但是我没有完全覆盖代码，请帮忙
public YourClassTest{
@Test
void apply() throws Exception {
AuthorizationFilter authorizationFilter = new AuthorizationFilter();
AuthorizationFilter.Config config = new YourClass.Config();
GatewayFilter filter =authorizationFilter.apply(config);
String st ;
st = new ObjectMapper().writeValueAsString(userRoleDetailsDTO);
MockServerHttpRequest expected = MockServerHttpRequest.get("/v1/profile").
header("Authorization","Bearer sdfsf",st,TestConstants.USER_DETAILS_HEADER).build();
MockServerWebExchange exchange = MockServerWebExchange.from(expected);
filter.filter(exchange,FilterChain);
String requestid;
ServerHttpRequest actual = exchange.getRequest();
assertEquals(expected,actual);
}
}
解决方法
我等了两天，有人会回答我的问题，但没人回答我的问题，但最终我解决了。我用过junit5
这是我正确的解决方法
@SpringBootTest(properties = { "spring.profiles.active=test" })
class AuthorizationFilterTest {
@Mock
GatewayFilterChain filterChain;
@MockBean()
RestTemplate restTemplate;
@Autowired
AuthorizationFilter authorizationFilter = new AuthorizationFilter();
@BeforeAll
public static void init() {
userRoleDetailsDTO = new UserRoleDetailsDTO();
RoleDTO roleDTO = new RoleDTO();
roleDTO.setName("ADMIN_ROLE");
roleDTO.setWeight(1);
userRoleDetailsDTO.setUserId("user::2f840056-e7aa-84m- 68e1-1e2ef697c78b");
userRoleDetailsDTO.setRoles(Stream.of(roleDTO).collect(Collectors.toList()));
}
@Test
void apply()
{
AuthorizationFilter.Config config = new AuthorizationFilter.Config();
Map<String,Object> profile = objectMapper.readValue(TestConstantsTest.ADMIN_PROFILE_RESPONSE,Map.class);
ResponseEntity<Map> profileMap = ResponseEntity.ok(profile);
Mockito.when(restTemplate.exchange(Mockito.anyString(),Mockito.any(HttpMethod.class),Mockito.any(HttpEntity.class),Mockito.eq(Map.class))).thenReturn(profileMap);
GatewayFilter filter = authorizationFilter.apply(config);
MockServerHttpRequest expected = MockServerHttpRequest.post("/v1/profile")
.header("Authorization",TestConstantsTest.ADMIN_INITIALISE_REQUEST_AUTH_HEADER).build();
MockServerWebExchange exchange = MockServerWebExchange.from(expected);
filter.filter(exchange,GatewayfilterChain);
ServerHttpRequest actual = exchange.getRequest();
assertEquals(expected,actual);
}
这是我的TestConstant.class
Class TestConstantTest
{
public static final String ADMIN_PROFILE_RESPONSE = "{\n" +
" \"code\":\"200\",\n" +
" \"data\":{\n" +
" \"myroles\":[\n" +
" {\n" +
" \"name\":\"ADMIN_ROLE\",\n" +
" \"weight\":\"1\"\n" +
" }\n" +
" ],\n" +
" \"userId=User\":\"manually-inserted-usser-user-id-normallt-uuid\"\n" +
" },\n" +
" \"message\":\"Success\",\n" +
" \"status\":1\n" +
" }";
public static final String ADMIN_INITIALISE_REQUEST_AUTH_HEADER ="Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpX" +
"VCJ9.eyJhdWQiOlsicmVzb3VyY2Utc2VydmVghingbshtYXBpIl0sImV4cCI6MTU5NTI0NDU2MywidXNlcl9uYW1lIj" +
