### Traditional JSON Verification (for comparison)

Source: https://skyscreamer.github.io/JSONassert

This example demonstrates the verbose, traditional approach to verifying JSON data, highlighting the complexity JSONassert aims to reduce.

```java
JSONObject data = getRESTData("/friends/367.json");  
 Assert.assertTrue(data.has("friends"));  
 Object friendsObject = data.get("friends");  
 Assert.assertTrue(friendsObject instanceof JSONArray);  
 JSONArray friends = (JSONArray) friendsObject;  
 Assert.assertEquals(2, data.length());  
 JSONObject friend1Obj = friends.getJSONObject(data.get(0));  
 Assert.true(friend1Obj.has("id"));  
 Assert.true(friend1Obj.has("name"));  
 JSONObject friend2Obj = friends.getJSONObject(data.get(1));  
 Assert.true(friend2Obj.has("id"));  
 Assert.true(friend2Obj.has("name"));  
 if ("Carter Page".equals(friend1Obj.getString("name"))) {  
 Assert.assertEquals(123, friend1Obj.getInt("id"));  
 Assert.assertEquals("Corby Page", friend2Obj.getString("name"));  
 Assert.assertEquals(456, friend2Obj.getInt("id"));  
 }  
 else if ("Corby Page".equals(friend1Obj.getString("name"))) {  
 Assert.assertEquals(456, friend1Obj.getInt("id"));  
 Assert.assertEquals("Carter Page", friend2Obj.getString("name"));  
 Assert.assertEquals(123, friend2Obj.getInt("id"));  
 }  
 else {  
 Assert.fail("Expected either Carter or Corby, Got: " + friend1Obj.getString("name"));  
 }  
```

### JSONassert Error Message Example

Source: https://skyscreamer.github.io/JSONassert

This is the output of a JSONassert comparison failure, illustrating how it pinpoints discrepancies in nested JSON structures, like an array element mismatch.

```text
friends[id=3].pets[]: Expected bird, but not found ; friends[id=3].pets[]: Contains cat, but not expected  
```

--------------------------------

### Simple JSON Comparison with JSONassert

Source: https://skyscreamer.github.io/JSONassert

Use JSONAssert.assertEquals for straightforward JSON comparisons. Set the last parameter to false to allow for flexible matching (ignoring order and extra elements), which is recommended for less brittle tests.

```java
JSONObject data = getRESTData("/friends/367.json");  
 String expected = "{friends:[{id:123,name:\"Corby Page\"},{id:456,name:\"Carter Page\"}]}";  
 JSONAssert.assertEquals(expected, data, false);  
```

--------------------------------

### JSON Comparison with Detailed Error Message

Source: https://skyscreamer.github.io/JSONassert

When JSONassert encounters a mismatch, it provides a detailed error message indicating the specific location and nature of the difference, such as expected vs. actual values in an array.

```java
String expected = "{id:1,name:\"Joe\",friends:[{id:2,name:\"Pat\",pets:[\"dog\"]},{id:3,name:\"Sue\",pets:[\"bird\",\"fish\"]}],pets:[]}";  
 String actual = "{id:1,name:\"Joe\",friends:[{id:2,name:\"Pat\",pets:[\"dog\"]},{id:3,name:\"Sue\",pets:[\"cat\",\"fish\"]}],pets:[]}"  
 JSONAssert.assertEquals(expected, actual, false);  
```
