Tip #2 Create a Mock Server in Agent Mode

Need to test your API before the backend’s ready? Try creating a Mock Server directly in Agent Mode. It’s a simple way to simulate real responses using your existing Collection’s Examples, perfect for developing and testing without waiting for live endpoints.

Prompt:

Create a new mock server for my @Library API so that I can start calling the endpoints. Add the mock url to the baseUrl variable.

Tip #3 Adding Tests to a Collection

With Agent Mode, you can add and run tests. Use pm.test() scripts to validate your endpoints locally and catch issues early.

Tip #5 Fork a Collection with Agent Mode

Need to experiment without affecting the main Collection? Fork it! Agent Mode makes it simple to clone and test locally, so you can explore and iterate safely.

Prompt:

Create a Fork of the @Library API collection in this Workspace. The fork name should be “development”.

Once created, open the “Get Book” request in the forked Collections so I can start making changes straight away.
