# REST API Test Suite Generator

Generates comprehensive API test suites from OpenAPI specs using Postman Collection SDK and Newman CLI. Creates parameterized test scenarios with environment-specific variables, auth flows, and assertion chains.

## Prerequisites

Node.js

## Installation

Use the upstream install or setup path that matches your environment:
- npm install postman-collection --save

Requirements and caveats from upstream:
- var fs = require('fs'), // needed to read JSON file from disk
- Collection = require('postman-collection').Collection,

Basic usage or getting-started notes:
- In this example snippet we will get started by loading a collection from a file and output the same in console.
- javascript
- myCollection;
