在Spring Controller的catch块中测试代码

我有以下结构的控制器：

@RequestMapping(value = "${foo.controller.requestMappingUrl.login}", method = RequestMethod.POST)
    public ResponseMessage<String> loginUser(
            @RequestParam("username") String username, HttpServletRequest httpServletRequest,
            HttpServletResponse httpServletResponse) {

    try {

       return fooService.login(username); // can mock test

    } catch (UserNotFoundException e) {
            //CANNOT MOCK TEST THIS BLOCK
            String errorMsg = LoggerUtil.printStackTrace(e);
            LOG.error("[RequestId: {}] UserNotFoundException: {}, Stack: {}", requestId, e.getMessage(), errorMsg);
            httpServletResponse.setStatus(HttpStatus.NOT_ACCEPTABLE.value());
            statusCode = StatusCode.UserNotFound.value();
            responseMessage.buildResponseMessage(StringUtils.EMPTY, HttpStatus.NOT_ACCEPTABLE, statusCode,
                    messageByLocaleService.getMessageResponse(statusCode, null, locale));
    }
}

当我模拟抛出异常UserNotFoundException时，我只得到NestedServletException . 即使我尝试添加expected = NestedServletException.class . corbetura报告表明代码块未包含在测试中 . 您是否有任何建议可以帮助测试catch块中的代码 .

要求的测试代码：

@SuppressWarnings("unchecked")
@Test(expected = UserNotFoundException.class)
    public void testControllerUserNotFoundException() throws Exception {
        Response resp = new Response();
        resp.setStatusCode(StatusCode.UserNotFoundErrorCode);
        when(fooService.login(any(String.class)).thenThrow(UserNotFoundException.class);

        mockMvc.perform(post("/service-user/1.0/auth/login?&username=test")
                        .contentType(contentType)).andExpect(status().isNotAcceptable())
                .andExpect(jsonPath("$.statusCode", is("ERRORCODE144")));

    }

和堆栈跟踪
