Running Collections with Postman Runner
What Is the Collection Runner?
The Collection Runner executes every request in a collection (or folder) in sequence, without manually clicking Send on each one. It's ideal for regression checks and end-to-end flows.
Starting a Run
Open the Runner from the collection's context menu, choose the environment, set the number of iterations and delay between requests, and click Run to execute the whole collection automatically.
Reading the Results
| Result | Meaning |
|---|---|
| Pass | All test assertions in that request succeeded |
| Fail | One or more assertions did not match |
| Skipped | Request was disabled or skipped in the flow |
Why It Matters
Running collections repeatedly makes it easy to catch regressions whenever an API changes, without repeating manual testing steps.
Running a collection once is useful, but Postman becomes even more powerful when each run uses different data - that's where data-driven testing comes in.
