How to compare json responses?

Question

I need to compare json response in beanshell sampler and print if the condition is passed or failed. Can someone please help, how do we compare it ? I already have a response in json format and one i will be getting another when the test is executed, i ned to compare those two word to word.

 I tried using if/else but then its not working properly.


JSONObject JsonResponseinput = new JSONObject();
JsonResponseinput.toString();

print(JsonResponseinput +  " = PASS");
    f.close();

String s=JsonResponseinput.toString();

if (s == JsonResponse)
{
    f = new FileOutputStream("output/path/API_OUTPUT.csv", true);
     p = new PrintStream(f);
     this.interpreter.setOut(p);
    print(s +  " = PASS");
    f.close();
}
Else
{
    print(JsonResponseinput +  " = FAIL")

}

There are at least 4 ways of doing this:

1. Using Jackson like:

   final JSONObject obj1 = /*json*/;
   final JSONObject obj2 = /*json*/;
   final ObjectMapper mapper = new ObjectMapper();
   final JsonNode tree1 = mapper.readTree(obj1.toString());
   final JsonNode tree2 = mapper.readTree(obj2.toString());
   if (tree1.equals(tree2)) {
        log.info('PASS');
   }
   else {
        log.info('FAIL')
   }
   

2. Using GSON like:

   JsonParser parser = new JsonParser();
   JsonElement o1 = parser.parse("{a : {a : 2}, b : 2}");
   JsonElement o2 = parser.parse("{b : 2, a : {a : 2}}");
   assertEquals(o1, o2); 
   

3. Using JsonSlurper like:

   def json1 = new groovy.json.JsonSlurper().parseText("json1")
   def json2 = new groovy.json.JsonSlurper().parseText("json2")
   
   if (json1 == json2) {
       log.info('PASS')
   } else {
       log.info('FAIL')
   }
   

4. Using JSONAssert like

   try {
       org.skyscreamer.jsonassert.JSONAssert.assertEquals("json1", "json2", false)
       println('PASS')
   }
   catch (Exception ex) {
       println('FAIL')
   }

P.S. Forget about Beanshell, since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for any form of scripting
