Access response size in postman test

Question

Is it possible to access the value of the response size in my postman test cases ?

While I am able to see the response size alongside the status code and the response time (both of which i can use in my test cases using responseCode.code and responseTime) I have not been able to use it in my tests. [I tried variables like responseSize and so forth to no success]

Answer 1

pm.response.responseSize will give you the response size of the body.

Answer 2

Adding an example to Sbaddam's excellent answer:

pm.test("response size", function () {
    pm.expect(pm.response.responseSize).to.be.equal(1252184);
});
