I am trying to write a test in Postman to check if JSON keys are present in the response I received from the server.

The response:

{
  "Result": 0,
  "ResponseStatus": {
    "ErrorCode": null,
    "Message": null,
    "StackTrace": null,
    "Errors": null
  },
  "ResponseHeader": {
    "Succeeded": true,
    "Errors": null
  },
  "SessionId": "XXX-XXX-XXX"
}

I want to check "Results, Errorcode, Message,Succeeded" etc..

Thanks!

• 1 What's your question? Where are you having trouble? – WillardSolutions Commented Oct 5, 2016 at 14:12

• @ZahidRahman — Why do you need to know details of the backend API in order to answer a question about writing a test against JSON that has already been successfully retrieved? – Quentin Commented Oct 5, 2016 at 14:18
• 2 @Quentin - the "JSON value check" is checking for json values. e.x : '"Succeeded": true' - it will check if true is presented. i want to check if Succeeded is presented. i want to achieve a backend api test (so i will know when the schema has changed) – abovebeyond15 Commented Oct 6, 2016 at 7:44

You could check the response scheme using:

var jsonData = JSON.parse(responseBody);
tests['response json contain Results'] = _.has(jsonData, 'Results');

According to your response body that you get, You can write simple test script for request under test section. You need to parse your json response first. The script will look like:

var jsonData = JSON.parse(responseBody);
tests["Succeeded with value true"] = jsonData.ResponseHeader.Succeeded === true;

similarly you can write tests for other checks.For sessionId I would suggest you to check it with sessionId where it gets generated(store it in environment and check with it in this request)
