How can I auto-generate test cases from a Postman collection?

Hey everyone,

I’m working on improving test coverage and was wondering—does Postman support any method to auto-generate test cases from an existing collection?

I’ve got a decent number of requests organized in folders, but manually writing tests for each one is time-consuming. Is there a recommended workflow or any scripts that can help generate test templates automatically based on the request/response structure?

Thanks!

Hey @siteloren :waving_hand:

Welcome to the Postman Community! :postman:

There are a few options in the platform that would allow you to auto-generate tests, based on the requests you have in the Collection. Postbot being the main option, there are several entry points in the platform and a number of different ways that tests can be created.

We recently highlighted some of these new ways in our monthly postman-drop - The latest being creating tests using Postbot inline, on the response section.

More information about Postbot can be found here:


You can also use the Generate tests option in the Collection actions menu:

This option will use Postbot to run your requests and they generate a set of tests based on the response details.


As much as we provide that automatic methods to create tests, it will always take a human to know if those tests are actually providing the value that you want.

  • Are they the correct tests for your context?
  • Are they too static and not testing your business logic or workflows?
  • Are they going to fail when the item’s that are important to you, start showing unexpected results?

Thanks a lot for the warm welcome and the helpful info! I’ll definitely check out Postbot and the “Generate tests” feature. Totally agree, it’s all about making sure those tests really align with what I need. Appreciate your support!
