Postman Introduction

What is Postman?

Postman is a popular tool for building, testing, and documenting APIs. It provides a user-friendly interface for sending HTTP requests and inspecting responses, without writing code.

Key Features

• Sending GET, POST, PUT, DELETE, and other HTTP requests.
• Organizing requests into Collections.
• Managing different Environments (e.g., Dev, QA, Production) with variables.
• Writing test scripts in JavaScript to automatically validate responses.
• Generating shareable API documentation.

Why Testers Like Postman

Its visual interface makes it easy to manually explore an API before writing automated tests, and its built-in scripting supports basic automated validation without a full test framework.
