如何使用mockMvc检查响应体中的String [英] How to check String in response body with mockMvc

问题描述

我有简单的集成测试

    @Test
public void shouldReturnErrorMessageToAdminWhenCreatingUserWithUsedUserName() throws Exception {
    mockMvc.perform(post("/api/users").header("Authorization", base64ForTestUser).contentType(MediaType.APPLICATION_JSON)
            .content("{\"userName\":\"testUserDetails\",\"firstName\":\"xxx\",\"lastName\":\"xxx\",\"password\":\"xxx\"}"))
            .andDo(print())
            .andExpect(status().isBadRequest())
            .andExpect(?);
}

在最后一行中我想比较在响应体中收到的字符串与预期的字符串

In last line I want to compare string received in response body to expected string

作为回应我得到：

MockHttpServletResponse:
          Status = 400
   Error message = null
         Headers = {Content-Type=[application/json]}
    Content type = application/json
            Body = "Username already taken"
   Forwarded URL = null
  Redirected URL = null

尝试了一些内容技巧（ ），身体（）但没有任何效果。

Tried some tricks with content(), body() but nothing worked.

推荐答案

@Sotirios Delimanolis回答做这个工作但是我一直在寻找比较这里的字符串mockMvc断言

@Sotirios Delimanolis answer do the job however I was looking for comparing strings within this mockMvc assertion

所以这里是

.andExpect(content().string("\"Username already taken - please try with different username\""));

当然我的断言失败了：

java.lang.AssertionError: Response content expected:
<"Username already taken - please try with different username"> but was:<"Something gone wrong">

因为：

  MockHttpServletResponse:
            Body = "Something gone wrong"

所以这是证明它有效！
