【问题描述】：

我正在测试一个通过 http 海报（即 PAW）工作的 api 端点，但我无法通过代码测试。

我是 Mockito 和 MockMVC 的新手，因此我们将不胜感激。

下面的测试：

 @Test
 public void createPaymentTest() throws Exception {
    User user = new User("ben", "password", "a@a.com");

    SuccessResponseDTO successDTO = new SuccessResponseDTO();
    successDTO.setSuccess(true);

    when(userService.getLoggedInUser()).thenReturn(user);
    when(paymentService.makePayment(Mockito.any(PaymentRequestDTO.class), Mockito.any(User.class))).thenReturn(successDTO.getSuccess());

    this.mockMvc.perform(post("/payment")).andExpect(status().isOk())
            .andExpect(content().contentType(MediaType.APPLICATION_JSON)).andDo(MockMvcResultHandlers.print())
            .andExpect(jsonPath("$.success").value(successDTO.getSuccess()));

}

SuccessResponseDTO 只包含一个属性，一个布尔值“成功”。

它正在测试的方法如下：

@RequestMapping(value = "/payment", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public SuccessResponseDTO createPayment(@RequestBody PaymentRequestDTO payment) {
    User loggedInUser = userService.getLoggedInUser();
    LOGGER.info("Logged in user found...creating payment...");

    Assert.notNull(payment.getAccountId(), "Missing user account id");
    Assert.notNull(payment.getPayeeAccountNumber(), "Missing payee acount number");
    Assert.notNull(payment.getPayeeName(), "Missing payee name");
    Assert.notNull(payment.getPayeeSortCode(), "Missing payee sort code");
    Assert.notNull(payment.getPaymentAmount(), "Missing payee amount");
    Assert.notNull(payment.getPaymentDescription(), "Missing payment description");

    Boolean paymentResult = paymentService.makePayment(payment, loggedInUser);

    SuccessResponseDTO successResponse = new SuccessResponseDTO();

    successResponse.setSuccess(paymentResult);

    return successResponse;
}

任何人都可以阐明堆栈跟踪：

【解决方案1】：

你也可以添加接受

 mockMvc.perform(post("/api/sender/sms/")
            .accept(MediaType.APPLICATION_JSON_UTF8)
            .contentType(MediaType.APPLICATION_JSON_UTF8)
            .content("{ \"serviceName\":\"serviceName\",  \"apiId\":\"apiId\",  \"to\":\"to\",  \"msg\":\"msg\" }")
    )
        .andExpect(MockMvcResultMatchers.status().isOk())
        .andReturn();

【解决方案2】：

您可能还缺少控制器类上的一些注释。确保使用 @EnableWebMvc 和 @Controller

【解决方案3】：

HTTP Error 415 Unsupported media type - 表示您发送的数据不受服务支持。在这种情况下，这意味着您没有在请求中设置 Content-Type 标头和实际内容。我想 JSON 是预期的内容，所以你的调用应该是这样的：

this.mockMvc.perform(post("/payment").contentType(MediaType.APPLICATION_JSON)
    .content("{\"json\":\"request to be send\"}"))
    .andExpect(status().isOk())
    .and_the_rest_of_validation_part
