.on('request', function (err, args) { if (!err) { // here, args.response represents the entire response object var rawBody = args.response.stream, // this is a buffer body = rawBody.toString(); // stringified JSON results.push(JSON.parse(body)); // this is just to aggregate all responses into one object expect(body.array.length === 3).to.equal(true)// **EXAMPLE** } })or
pm.expect(res).to.have.property('code', 200);pm.expect(res).to.have.property('status', 'OK');both check status code of the response on your request.
