Introduction

While making, sharing, and testing the APIs, you used the API client called Postman. 

So in Postman, there is Newman which is a Command-line Collection runner which you can immediately use to execute and test a Postman Collection.

Let's dive into the topic to explore more about Newman in Postman.

Postman

An API testing tool is called Postman. It is an HTTP client that examines HTTP requests using a graphical user interface, allowing us to get various results that must then be verified.

Methods

Numerous endpoint contact techniques are available in Postman. Among the most popular, along with what they do, are the following:

  • GET: Obtain knowledge
  • POST: Include details
  • PUT: Replace the text
  • PATCH: Update specific data
  • DELETE: Remove the information

Collections

It is possible to group various requests using Postman. This function, called "collections," facilitates test organisation.

These collections, essentially folders where requests are stored, can be organised however the team sees fit. They can also be imported and exported.

Newman in Postman

For Postman, Newman is a collection runner on the command line. It enables simple running and testing of a Postman collection from the command line. It is designed to be extensible, so it can be quickly combined with your build systems and continuous integration servers.

Command Line Interface

A text-based user interface (UI) known as a command-line interface (CLI) is used to interact with computers and run programmes. Command-line user interfaces, console user interfaces, and character user interfaces are further names for command-line interfaces. CLIs accept keyboard input for commands; the computer executes the commands entered at the command prompt.

When computers were first invented, the command-line interface, or CLI, was the principal (or major) method of communication with them. In the 1970s and 1980s, it was typical. When you use a command line interface, a shell converts your text commands into the appropriate operating system commands or functions. It is no longer as prevalent as it once was because powerful GUIs are now available. 

Continuous Integration

A developer frequently works in a team or group, and the team may be dispersed throughout the world or within a single office. Even though you may not have met, you all collaborate on the same project, creating unique modules or changing the same code base. Let's say you modify an existing piece of code or add a new one. Everyone must now see this update in order for them to be aware of the program change you made. 

Continuous integration refers to integrating your program and modifications continually, so they appear in the web repository (or cloud).

Newman Vs. Postman

Newman Vs. Postman

Postman's Benefits

  • UI that is straightforward and easy to use.
  • All HTTP methods are supported.
  • Simple to use from a browser or application with an account.
  • many different status codes for simple tracking.

Postman's Drawbacks

  • Small testing range.
  • Using pre-written scripts for various projects is not possible.
  • Restrictive integration

Frequently Asked Questions

What is the use of Newman?

For Postman, Newman is a command-line Collection Runner. It allows you to use the command line to immediately execute and test a Postman Collection.

Does Jenkins have an API?

Jenkins offers a remote access API that is machine-consumable for its features. Presently, it is available in three flavours: XML. JSON that supports JSONP.

Is Cypress good for API testing?

Cypress is a wonderful testing tool that is also highly beneficial when testing AP.

Can we run multiple collections in Postman?

Workflows can be created by running collections on various data sets numerous times.

Is Postman a REST API?

Postman started out as a REST client and has since developed into the extensive Postman API Platform that it is today.
