Using Postman tool in API testing gives testers a lot of benefits. How is the specification? Let's find out through this article right now!
What is Postman?
Postman is a very prominent toolkit that supports users a lot in manipulating APIs, the most popular being REST. Its free version provides almost all the necessary functionality for the tester community and developers in general.
All HTTP protocols (POST, PUT, GET, DELETE, PACTH...) are within Postman's processing capabilities
Besides, Postman also allows users to save the history of requests, extremely convenient for reuse when needed.
What components does Postman include?
Postman includes 03 main components as follows:
Setting
This is where all the information related to the general installation is included:
- All account information (log in, log out, sync data...).
- Custom settings like shortcuts, formats, themes...
- Import data from outside.
Collections
Has the role of storing information of the APIs based on folder or time.
Content API
A place to display detailed content about the API, as well as support sections for the purpose of testing.
It can be said, Content API is one of the components that testers need to interact and work with a lot.
The Content API has three main components:
- Environments: Developers can simply switch to the test environment without having to change the URL of each request.
- Request: Contains the main information of the API (URL, method, header, body).
- Response: Include the information returned after sending request.
Benefits of API testing using Postman tool
It can be said that Postman is the most commonly used toolkit in API testing.
Thanks to Postman's help, testers and programmers don't need to spend time writing any lines of code and still call the REST API extremely quickly.
Moreover, Postman is also favored by users in API testing work thanks to the following benefits:
- Allows users to create collections of their API calls through Collections, with multiple subdirectories and requests within. This factor helps process of organizing test suites become more professional.
- Supports test creation and successful HTTP response status determination.
- Ensure API test coverage.
- The process of using Collections and Newman will ensure that API testing runs in iterations, saving time for multiple duplicate tests.
- Collections and environments in Postman will be imported/exported, making file sharing free and easy for users.
- Has the ability to test HTTP response status.
- Debugging will be made more flexible, thanks to the console's support for inspecting retrieved data provided by Postman.
- Provides continuous integration for development operations and can be maintained.
