Explain what collections are in the Postman tool and how they are used to organize requests

In Postman, collections are organized sets of HTTP requests grouped into a logical structure. They allow you to store, manage, and run related requests together, simplifying API testing.

Collections are used for:

• Organizing requests by projects or functionality.
• Reusing requests and scripts.
• Automating testing with collection runs (Collection Runner).
• Collaborating within a team, as collections can be exported and imported.

Thus, collections help structure API work and simplify test management.
