Introduction
Postman is a widely-used API (Application Programming Interface) testing tool. This tool was first launched in 2012. Postman offers several unique features and benefits. One can use
Postman Online to build, design, test, modify, and document various APIs. This tool does
not require licensing costs and has emerged as the largest framework for enhanced and
faster API testing. Moreover, Postman supports Continuous Delivery or Continuous
Deployment (CI/CD), making it well-suited for teams with any capacity. This platform
supports easy maintenance of the test suites using Collections. Furthermore, Postman API
allows one to import or export Environments and Collections, thus enabling easy file
sharing. Additionally, Postman has extensive community support and comes with the
Postman Console to debug the test steps.
This content provides insight into the essential features of the Postman API testing tool and
why one must consider using this tool. Read on to know more.
Essential Features Of Postman API
The Postman API testing tool has several useful features that facilitate dynamic API testing
functions.
Let us look at the most essential Postman features in detail.
1. Postman Echo Feature
Postman Echo is a sanity checker feature and learning tool in the Postman API testing
framework. It enables users to test their REST clients and efficiently make sample API calls.
2. Postman Visualizer Feature
Postman Visualizer feature enables the developers to visually represent their request
responses using HTML, CSS, JavaScript, etc.
3. Built-in Libraries Feature
Postman offers multiple high-functioning in-built libraries. These libraries simplify the
developers’ work by providing multiple functionalities.
4. Workflow Control Feature
The Workflow Control feature in Postman aims to streamline various functions on this API
testing platform.
5. Collaboration Features Feature
Postman offers collaboration features like tagging, branching, commenting, forking, pull
requests, etc., to make collaboration processes easier and more effective.
6. Collection-Level Information Feature
Postman’s Collection-Level Information feature enables the users to reuse their old codes,
scripts, etc., on other projects to save time.
7. Monitors For Regression Testing Feature
The Monitors Feature in Postman facilitates Regression testing. This helps the users flag the
issues early and perform improved Automated Regression Testing.
8. Built-in GraphQL Support Feature
The Postman API testing platform has an in-built GraphQL Support that supports the
GraphQL variables and sends the GraphQL queries effectively.
9. Documentation Pizzaz Feature
Documentation Pizzaz in Postman enable the users to add images and gifs to their
documentation to make it unique.
Why Use Postman?
Mentioned below are some of the significant reasons that make Postman one of the
industry’s most prominent API testing frameworks.
1. Accessibility: One can use Postman anywhere after installing the software into the
device by logging in to the account.
2. Use Collections: The Postman API testing tool allows users to build collections for their
API calls. Every set can create multiple requests and subfolders to organize the test
suites.
3. Test Development: Users can test checkpoints verification of successful HTTP response
status added to every API- call using Postman.
4. Automation Testing: One can perform tests in several repetitions or iterations by using
the Collection Runner or Newman.
5. Creating Environments: Multiple environments result in less replication of the tests.
Therefore, users can use the same collection for different settings.
6. Debugging: One can effectively debug the tests. The Postman console helps users track
the data being retrieved.
7. Collaboration: Moreover, users can import or export collections and environments to
enhance the sharing of files.
8. Continuous Integration: In addition to the above points, one can support continuous
integration on Postman.
Conclusion
To summarise, Postman is a popular Application Programming Interface (API) testing tool
launched in 2012. This tool is used to build, design, test, modify, and document various APIs.
Postman supports Continuous Delivery or Continuous Deployment (CI/CD). Furthermore, it
allows one to import or export Environments and Collections, thereby enabling easy file
sharing. The Postman API testing tool has several useful features that facilitate dynamic API
testing functions. Various important features of Postman include Postman Echo, in-built
libraries, Postman Visualizer, etc. Furthermore, Postman API includes Workflow Control,
Collection-Level Information, collaboration features, Monitors, Documentation Pizzaz, in-
built GraphQL Support, etc. Moreover, one can use Postman anywhere after installing the
software into the device by logging in to the account.
