Can you explain what the Newman tool is and what it is used for in API testing?

Newman is a command-line utility for running Postman collections from the command line. It allows automating API testing by executing requests described in Postman collections and checking responses.

Main uses of Newman:

• Integrating API tests into CI/CD pipelines.
• Running tests without the Postman GUI.
• Generating test reports.

Example of running a collection:

newman run my_collection.json

Thus, Newman helps automate and scale API testing.
