// example using response assertions

// example using pm.response.to.be*
pm.test("response must be valid and have a body", function () {
     // assert that the status code is 200
     pm.response.to.be.ok; // info, success, redirection, clientError,  serverError, are other variants
     // assert that the response has a valid JSON body
     pm.response.to.be.withBody;
     pm.response.to.be.json; // this assertion also checks if a body  exists, so the above check is not needed
