如何断言JSON数组中具有相同键但值不同的两个JSON对象

Question

我必须断言两个具有相同键的json对象，它们包含在json数组中，如下所示。

响应值

[｛"message"："Rest Endpoint不应为空"｝，｛"message"："无效URL"｝]

但是我在断言响应时遇到了一个问题，对象不会像我试图断言的那样接收，因为响应对象的顺序有时会发生变化，从而导致断言失败。

下面是我目前用来断言对象的代码。

Assert.assertEquals(jsonArray.getJSONObject(0).get("message").toString(), "Rest Endpoint should not be empty");
Assert.assertEquals(jsonArray.getJSONObject(1).get("message").toString(), "Invalid URL");

有时我收到的内容会导致断言错误。

jsonArray.getJSONObject(0).get("message").toString() as "Invalid URL" and 
jsonArray.getJSONObject(1).get("message").toString() as "Rest Endpoint should not be empty"

完整代码块

//Requesting the resource API (save) with Payload
Response response = RestAssured.given().contentType("application/json").body(mydata).post("/api/v1/applications");
logger.info("/Save - Request sent to the API");
//Check valid Json responce
JSONArray jsonArray = new JSONArray(response.body().asString());
System.out.println(jsonArray.length());
Assert.assertEquals(jsonArray.length(), 2);
logger.info("/Save - Json Response validity pass");
//Check Response status code
Assert.assertEquals(response.getStatusCode(), 400);
logger.info("/Save - Responce code 400 OK");
//Check Response Objects received       
Assert.assertEquals(jsonArray.getJSONObject(0).get("message").toString(), "Rest Endpoint should not be empty");          
Assert.assertEquals(jsonArray.getJSONObject(1).get("message").toString(), "Invalid URL");
logger.info("/getAllApplications - Json Response received as :" + jsonArray.getJSONObject(0).get("message").toString());
logger.info("/getAllApplications - Json Response received as :" + jsonArray.getJSONObject(1).get("message").toString());
logger.info("/Save -3 API Testing Completed [Test 'RestEndPoint' field validation]");

Answer 1

找到解决方案

//Create a string list and iterate the Json array to fetch the required text with the same key 
List<String> responseList = new ArrayList<String>(jsonArray.length());
for (int i = 0; i < jsonArray.length(); i++) {
responseList.add((jsonArray.getJSONObject(i).getString("message")));
}
//Assert the list
org.junit.Assert.assertThat(responseList, hasItems("Rest Endpoint should not be empty", "Invalid URL"));

Answer 2

您可以使用hasItem和assertThat，只需将jsonArray转换为List即可。

Assert.assertThat(Arrays.asList(exampleStringArray), hasItem("Rest Endpoint should not be empty"));
Assert.assertThat(Arrays.asList(exampleStringArray), hasItem("Invalid URL"));

其中CCD_ 4是CCD_。

Answer 3

如果您的用例使用Maven，我会包含这个库

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.8</version>
</dependency>

这将帮助您比较对象，而不必担心顺序。
