Why Use Newman?

• Easy Commands: Newman understands simple commands you type on your computer. There is no graphical stuff, it’s just plain text.
• Repeatability: Once you create a bunch of tests in Postman, Newman lets you run them over and over without clicking buttons.
• No-Click Testing: You don’t need to open Postman and click around to run your tests. Newman does it quietly in the background.

Newman is a command-line tool that lets you run your Postman collections directly from your computer’s command prompt. It extends the functionality of Postman by enabling the execution of these collections in a non-graphical environment. it lets you automatically test your APIs, which is a huge time-saver, especially when you have many tests.
