如何在来自其余模板的抛出异常下为 if else 条件编写 Junit

如何解决如何在来自其余模板的抛出异常下为 if else 条件编写 Junit

我是 Junit 的新手。我阅读了 Mockito 的基础知识。我不知道如何为测试代码覆盖率编写 Junit。 我正在使用 rest 模板调用来接收发送请求的响应对象。 我正在这里抛出的异常 (HttpStatusCodeException) 下执行一些逻辑。 下面是我的代码：

public void processData(Request data,HttpHeaders headers,String priority) throws JsonProcessingException {

    try {

        httpentity<Request> reqEntity = new httpentity<>(data,headers);
        ResponseEntity<Response> helloResponse = restTemplate.postForEntity(someendpoint,reqEntity,Response.class);
        if (priority.equals("low")) {
            func1();
        } else {
            func2();
        }

    } catch (HttpStatusCodeException ex) {

        if (ex.getStatusCode().equals(HttpStatus.SERVICE_UNAVAILABLE) && priority.equals("low")) {

            func3();

        } else if (ex.getStatusCode().equals(HttpStatus.SERVICE_UNAVAILABLE) && priority.equals("high")) {

            func4();

        }

        else if (ex.getStatusCode().equals(HttpStatus.FORBIDDEN) && priority.equals("low")) {

            func5();

        }

        else if (ex.getStatusCode().equals(HttpStatus.FORBIDDEN) && priority.equals("high")) {

            func6();

        }

        else {

            ObjectMapper mapper = new ObjectMapper();
            Response response = mapper.readValue(ex.getResponseBodyAsstring(),Response.class);
            if (priority.equals("low")) {
                func7();
            } else {
                func8();
            }
            
        }

    }
}

}

得到一些帮助会很有帮助。

解决方法

按如下操作。

@Test
public void test1(){

Mockito.when(restTemplate.postForEntity(ArgumentMatchers.any(),ArgumentMatchers.any,ArgumentMatchers.<Class<Response>>any())).thenReturn(new ResponseEntity<>(new Response(),HttpStatus.ok));
  //do your call and assertion
  //processData( data,headers,priority)
}

异常覆盖测试

  @Test
    public void testException1(){
    
    doThrow(HttpClientErrorException(HttpStatus.SERVICE_UNAVAILABLE).when(restTemplate).postForEntity(ArgumentMatchers.any(),ArgumentMatchers.<Class<Response>>any());
    //do your call and assertion
    //processData( data,"low")
    }
    
    
    
    @Test
    public void testException2(){
         doThrow(HttpClientErrorException(HttpStatus.FORBIDDEN).when(restTemplate).postForEntity(ArgumentMatchers.any(),"low")
    }

  

   

 @Test
 public void testException3(){ 
         doThrow(HttpClientErrorException(HttpStatus.SERVICE_UNAVAILABLE).when(restTemplate).postForEntity(ArgumentMatchers.any(),ArgumentMatchers.<Class<Response>>any());
            //do your call and assertion
            //processData( data,"high")
            }
            
            
            
 @Test
 public void testException4(){
            
            doThrow(HttpClientErrorException(HttpStatus.FORBIDDEN).when(restTemplate).postForEntity(ArgumentMatchers.any(),"high")
            }
