REST Assured 72 - How To Compare Part Of JSON Objects And Arrays Using JSONassert Library

REST Assured 系列汇总 之 REST Assured 72 - How To Compare Part Of JSON Objects And Arrays Using JSONassert Library

介绍

很多时候我们只需比较特定某部分的 JSON Objects 或 JSON Arrays。例如：假设我们创建一个新的订单并获取订单细节。当我们获取所有订单信息时，我们只需要验证刚创建的那个新的订单，不是验证所有的订单。

前提条件

添加 JSONassert 依赖

<!-- https://mvnrepository.com/artifact/org.skyscreamer/jsonassert -->
<dependency>
    <groupId>org.skyscreamer</groupId>
    <artifactId>jsonassert</artifactId>
    <version>1.5.0</version>
    <scope>test</scope>
</dependency>

请先阅读下面文章，了解 JSONassert Java library 基本概念 ，不同的比较模式和断言 JSON Objects 和 Array。

Introduction To JsonAssert Library

比较部分 JSON Objects

JSON Object 1

{
    
    
  "lastName": "Animesh",
  "firstName": "Prashant",
  "address": {
    
    
    "city": "Kolkata",
    "state": "WB"
  }
}

JSON Object 2

{
    
    
  "lastName": "Animesh",
  "firstName": "Prashant",
  "communicationAddress": {
    
    
    "city": "Kolkata",
    "state": "WB"
  },
  "skills": [
    "CA",
    "BCOM"
  ]
}

我们需要比较第一个 JSON Object 中的 “address” object 和第二个 JSON Object 中的 “communicationAddress” object 的值是否相等。我们分别用 JsonPath 的方法来获取想要的部分 JSON Objects，然后用 assertEquals() 方法来比较。

import org.json.JSONException;
import org.json.JSONObject;
import org.skyscreamer.jsonassert.JSONAssert;
import org.skyscreamer.jsonassert.JSONCompareMode;
 
public class ComparePortionOfJsonObjects {
    
    
	
	public static void main(String[] args) throws JSONException {
    
    
		
	JSONObject jsonObject1 = new JSONObject("{\r\n" + 
			"  \"lastName\": \"Animesh\",\r\n" + 
			"  \"firstName\": \"Prashant\",\r\n" + 
			"  \"address\": {\r\n" + 
			"    \"city\": \"Kolkata\",\r\n" + 
			"    \"state\": \"WB\"\r\n" + 
			"  }\r\n" + 
			"}");
	JSONObject jsonObject2 = new JSONObject("{\r\n" + 
			"  \"lastName\": \"Animesh\",\r\n" + 
			"  \"firstName\": \"Prashant\",\r\n" + 
			"  \"communicationAddress\": {\r\n" + 
			"    \"city\": \"Kolkata\",\r\n" + 
			"    \"state\": \"WB\"\r\n" + 
			"  },\r\n" + 
			"  \"skills\": [\r\n" + 
			"    \"CA\",\r\n" + 
			"    \"BCOM\"\r\n" + 
			"  ]\r\n" + 
			"}");
	
	// I want to assert address objects are same in both
	// Since "address" and "communicationAddress" are JSON Objects so we need to use proper method i.e. getJSONObject()
	JSONAssert.assertEquals(jsonObject1.getJSONObject("address"), jsonObject2.getJSONObject("communicationAddress"), JSONCompareMode.LENIENT);
   }
}

比较部分 JSON Arrays

JSON Array 1

[
  {
    
    
    "id": 1,
    "first_name": "Giavani",
    "last_name": "Skellorne"
  },
  {
    
    
    "id": 2,
    "first_name": "Patton",
    "last_name": "Buchett"
  }
]

JSON Array 2

[
  {
    
    
    "id": 1,
    "first_name": "Giavani",
    "last_name": "Skellorne"
  },
  {
    
    
    "id": 2,
    "first_name": "Harland",
    "last_name": "Brookwood"
  },
  {
    
    
    "id": 3,
    "first_name": "Leigh",
    "last_name": "Gatteridge"
  }
]

上两个 JSON Array，想比较比较数组中的第一个 objects

import org.json.JSONArray;
import org.json.JSONException;
import org.skyscreamer.jsonassert.JSONAssert;
import org.skyscreamer.jsonassert.JSONCompareMode;
 
public class ComparePortionOfJsonArrays {
    
    
	
	public static void main(String[] args) throws JSONException {
    
    
		
		JSONArray jSONArray1 = new JSONArray("[\r\n" + 
			"  {\r\n" + 
			"    \"id\": 1,\r\n" + 
			"    \"first_name\": \"Giavani\",\r\n" + 
			"    \"last_name\": \"Skellorne\"\r\n" + 
			"  },\r\n" + 
			"  {\r\n" + 
			"    \"id\": 2,\r\n" + 
			"    \"first_name\": \"Patton\",\r\n" + 
			"    \"last_name\": \"Buchett\"\r\n" + 
			"  }\r\n" + 
			"]");
	
		JSONArray jSONArray2 = new JSONArray("[\r\n" + 
			"  {\r\n" + 
			"    \"id\": 1,\r\n" + 
			"    \"first_name\": \"Giavani\",\r\n" + 
			"    \"last_name\": \"Skellorne\"\r\n" + 
			"  },\r\n" + 
			"  {\r\n" + 
			"    \"id\": 2,\r\n" + 
			"    \"first_name\": \"Harland\",\r\n" + 
			"    \"last_name\": \"Brookwood\"\r\n" + 
			"  },\r\n" + 
			"  {\r\n" + 
			"    \"id\": 3,\r\n" + 
			"    \"first_name\": \"Leigh\",\r\n" + 
			"    \"last_name\": \"Gatteridge\"\r\n" + 
			"  }\r\n" + 
			"]");
	
	// I want to assert address objects are same in both
	// Since index elements in both arrays are JSON objects so using proper method i.e. getJSONObject
	JSONAssert.assertEquals(jSONArray1.getJSONObject(0), jSONArray2.getJSONObject(0), JSONCompareMode.LENIENT);
   }
}

你也可以比较 JSON Object 中的一部分和 JSON Array 中的一部分。但是要注意，比较的部分一定要是相同的 Type，不然编译会出错。
