Question

我有一个使用spring webflux和电抗器的休息控制器，我正在为控制器编写单元测试。请在下面的代码段中查找并帮助我编写用于测试.doOnError块的单元测试方法。

我尝试使用Mockito引发异常

doThrow（CriticalException.class） .when（myService）.myMethod（object）;

This is my unit test


StepVerifier.create(
Mono.just(
                webTestClient.post() 
                       .uri("/endpoint")
                       .accept(MediaType.APPLICATION_JSON) 


                       .body(BodyInserters.fromObject(requestJson)) //Set the body of the request to the given synchronous Object
                                            //Returns:a Mono with the response
        //Act
                       .exchange()  //Perform the exchange 
        //Assert        
                       .expectStatus().isOk() 
                       .expectBody(Agreement.class)
                       .returnResult()
                       .getResponseBody()))
                .expectNextMatches(agreementResponse -> {
                        assertNotNull(agreementResponse.getAgreementParticipant());
                        return true; 
                }) 
                .expectComplete()
                .verify();

这是我的控制人

return Mono.fromCallable(() -> { 
            myService.myMethod(object);
            return object;
        }).log().subscribeOn(Schedulers.elastic())
                .map(p -> ResponseEntity.ok(p))
                .defaultIfEmpty(ResponseEntity.notFound().build())
                .doOnError(e -> { 
                    LOGGER.error(LOG_FORMAT, e.getMessage(), e.getStackTrace());                
                }); 


Mockito is not returning exception while myService.myMethod(object) is been called.
Please suggest proper way to write test for .defaultIfEmpty and .doOnError blocks

Answer 1

返回CriticalException.class而不是在模拟myService.myMethod(object)时抛出exception

例如：

Mono

在下面找到示例代码段

Mockito.doReturn(Mono.error(Exception::new)).when(service).callableMethod();

Mono.doOnError（）反应堆模块单元测试
