Few things about API Automation

We often need to automate the test cases which are repeatedly executed, like regression cases. Similarly, in the case of API testing, there might be some cases in which we need to execute before every release and those cases can be automated.

Many tools for API automation are quite popular. Such as:

• SoapUI

• Katalon studio

• Postman

• Jmeter

• REST Assured

SoapUI: It’s a very popular tool for API testing. You can do functional, load, security and compliance tests on your API using SoapUI.

Katalon Studio: Built on the top of Selenium and Appium, Katalon Studio is a free and powerful automated testing tool for Web testing, API testing, and Mobile testing.

Postman: Postman is free and helps you be more efficient while working with APIs. It has all the capabilities to develop and test APIs.

JMeter: Though JMeter is mostly used for performance and load testing, it can also be used for API functional testing to a good extent.

REST Assured: REST Assured is a Java-based library that is used to test RESTful Web Services. The library can be included in the existing framework and call its methods directly for fetching response in JSON format and then perform required actions.
