How to compare json responses?

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")

}

I use a tool called DeltaJSON from DeltaXML for JSON comparison there is a neat GUI and REST interface. You could use the REST API and parse the response.

You can compare 2 JSON Response using following ways:

  1. Extract both the JSON Responses using JSON Extractor [extract full Response]

  2. Use JSR223 Sampler to process the code in Script area

    String response1 = vars.get("jsonOutput1");
String response2 = vars.get("jsonOutput2");

if (response1.equals(response2)) {
log.info("Responses are equal");
}
else {
    log.info("Responses are not equal");
}

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
