Postman (newman) test scripts for HWs

We will post

1. sample tests before HW deadline so you can have a sense of what the tests looks like and write your own tests.

2. actual grading tests after HW deadline so you can double check.

Postman (newman) is a javascript tool to test RESTful services. You can change the method (GET/POST/DELETE/PUT, etc.), authentication (Bearer Token/OAuth, etc.), Headers, Params(usually for GET), Body (usually for POST) for a certain request.

There are two scripts part you could write: Pre-request Script and Tests

• Pre-request Script runs before the request is made, you may generate some random value and set to global variables.
• Tests runs after the request is done, you may make unit tests to assert on the response you get.
