+
+```javascript
+var _ = require('lodash'),

+    chaiPostman = require('chai-postman'),
+
+    req,
+    res,
+    expect = chai.expect;
+
+chai.use(chaiPostman(sdk, _));
+
+// create postman-collection request and response instances
+req = new sdk.Request({
+    header: [{
+        key: 'Content-Type',
+        value: 'application/json; charset=utf-8'
+    }]
+});
+res = new sdk.Response({ code: 200 });
+
+// request assertions
+expect(req).to.be.a.postmanRequest;
+expect(req).to.have.header('Content-Type'); // an optional second argument can also be provided to assert value
+
+// response assertions
+expect(res).to.be.a.postmanResponse;
+expect(res).to.have.statusCode(200);
