我正在尝试使用以下代码为我的控制器编写测试。我想对 catch 块语句中的代码进行测试,但我无法编写。我想在 catch 块中返回一个带有失败代码和消息的服务器响应。
@PostMapping(COUNTERS)
public ResponseEntity<?> getCounters(@Valid @RequestBody ApartmentCounterListRequest requestData) {
try {
log.debug("Entering API for counter list");
ApartmentCounterListResponse apartmentCounterListResponse = counterService.getAllCounters();
return ResponseEntity.ok(apartmentCounterListResponse);
} catch (Exception exception) {
log.error("Exception in counter list :: ", exception);
ServerResponse serverResponse = ResponseBuilder.buildVendorFailureMessage(new ServerResponse(),
RequestResponseCode.EXCEPTION);
return ResponseEntity.ok(JsonResponseBuilder.enquiryResponse(serverResponse));
}
}
我的测试代码如下:
@Test
@DisplayName("Should return ServerResponse with failure data.")
void Should_Return_Server_Response_On_Exception() throws Exception {
/*given*/
ApartmentCounterListRequest apartmentCounterListRequest = ApartmentTestUtil.getApartmentCounterListRequest.
apply("test", "test");
Mockito.when(counterServic.getAllCounters()).thenThrow(new Exception());
// ServerResponse serverResponse = ApartmentTestUtil.getServerExceptionServerResponse.get();
/*then*/
mockMvc.perform(
post(COUNTER_URL)
.contentType(APPLICATION_JSON)
.content(objectMapper.writeValueAsString(apartmentCounterListRequest)))
.andExpect(status().isOk())
.andExpect(MockMvcResultMatchers.jsonPath("$.resultCode", Matchers.is("-6")));
verify(counterService, times(1)).getAllCounters();
}
运行此测试时出现以下错误:
org.mockito.exceptions.base.MockitoException:
Checked exception is invalid for this method!
Invalid: java.lang.Exception
我已经浏览了以下一些帖子,但还没有找到合适的答案。

谁能帮我写一个覆盖 catch 块的测试或者告诉我怎么做?
我在我的控制器中有这个 try catch 来处理任何意外的异常。对于不同的 api,我必须使用不同的响应代码和消息发送响应,这不允许我使用异常处理程序。
答案 0 :(得分:6)
您正在模拟的方法没有声明已检查的异常,因此 Mockito 无法从那里抛出异常。尝试让模拟抛出未经检查的异常(即 RuntimeException)。

您可以尝试使用 willAnswer
Mockito.when(counterServic.getAllCounters()).thenAnswer(x -> {throw new Exception() });
也许这有点误用,因为 Answer 用于更复杂的返回时间
