Postman Collection Runner

What is the Collection Runner?

The Collection Runner executes every request within a Collection (or a chosen folder) sequentially, without needing to click "Send" on each one individually.

Key Features

• Running requests with different sets of data using a CSV or JSON data file (data-driven testing).
• Choosing the number of iterations and the delay between requests.
• Viewing a pass/fail summary of all assertions written in each request's Tests tab.

Why Testers Use It

The Collection Runner turns a set of individual manual requests into a lightweight, repeatable regression suite that can be run before every release.
