Newman vs Postman: Know the Key Differences for API Testing

Newman and Postman are two popular tools used for API testing, but they serve different purposes and have distinct features. Postman is a comprehensive API development and testing platform that provides a user-friendly graphical interface, while Newman is a command-line tool developed by Postman that enables the execution of Postman collections in an automated manner.

In this guide, we will explore the differences between Newman and Postman, and provide an overview of their respective features and use cases. By the end of this guide, you should have a better understanding of which tool is best suited for your API testing needs.

What is Newman in Postman

Newman Postman is a command-line tool that allows developers to run Postman collections and environments in a continuous integration (CI) environment. Postman is a popular API development tool that allows developers to design, test, and document APIs. Newman, on the other hand, is a tool that allows developers to automate API tests using Postman collections and environments.

With Newman Postman, developers can easily automate API tests and ensure that their APIs are working as expected. Newman supports a range of integrations and plugins, making it a versatile tool for API development. However, there are some limitations to Newman Postman that developers should be aware of, such as its complexity to set up and configure slow test execution, and cost for large-scale use.

What is the Difference Between Newman and Postman

There are many developers often confused about Postman and Newman. Literally, they are both API development tools, but they serve different purposes.

Features and Functionality

Postman is a desktop application that allows developers to test APIs. Newman, on the other hand, is a command-line tool that allows developers to run Postman collections and environments in a continuous integration (CI) environment.

API Testing

While Postman is designed for manual API testing and development, Newman is designed for automated API testing and integration with a CI/CD pipeline. Newman allows developers to automate API tests using Postman collections and environments, making it easier to ensure that APIs are working as expected.

UI

Another difference between Postman and Newman is their user interface. Postman has a graphical user interface (GUI) that allows developers to interact with APIs visually, while Newman has a command-line interface (CLI) that requires developers to use commands to interact with APIs.

Cost

There is a difference in cost between Postman and Newman. Postman offers a free version of its software that provides a limited set of features, while Newman is an open-source command-line tool that is freely available for download and use. However, Postman also offers a paid version of its software that provides additional features and functionality, such as team collaboration tools, API monitoring, and more. Similarly, there are commercial versions of Newman available that offer additional features and support.

Finally, while Postman is designed for manual API testing and development with a GUI, Newman is designed for automated API testing and integration with a CLI.

Postman Newman Alternative: Apidog

Apidog provides support for exporting test cases to Apidog CLI, Postman, and JMeter formats, making it easy to integrate API testing into your continuous integration process.

Apidog - An integrated platform for API design, debugging, development, mock, and testing

Download the Apidog API management tool here. Perfectly compatible with macOS, Windows, and Linux. Web version is also available.

The Apidog CLI is designed specifically for running Apidog test cases in the command line, providing a streamlined way to execute tests and automate the testing process. By exporting test cases to Apidog CLI, developers can easily integrate API testing into their build processes and ensure that APIs are tested thoroughly and consistently.

In addition to Apidog CLI, Apidog also supports exporting test cases to Postman and JMeter formats, providing developers with greater flexibility in their testing approach. With these export options, developers can choose the testing tool that best suits their needs and integrate API testing seamlessly into their development workflow.
