问题
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,我想比较响应体中收到的字符串和期望的字符串
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
尝试使用content(),body()但没有任何效果。

你可以致电andReturn()
并使用returnsMvcResult
对象获取内容为aString
。见下文:
MvcResult result = 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())
.andReturn();
String content = result.getResponse().getContentAsString();
// do what you will

@Sotirios Delimanolis回答了这项工作,但我正在寻找比较这个mockMvc断言中的字符串
所以在这里
.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"
所以这证明它有效!

Spring MockMvc现在直接支持JSON。所以你只说:
.andExpect(content().json("{'message':'ok'}"));
并且不像字符串比较,它会说"缺少字段xyz"或"消息预期'确定'得到'nok'。
这个方法是在Spring 4.1中引入的。
