Automation testing uses frameworks to run tests. Each framework is scripted with the rules of automation about the software to be tested. This framework is integrated with the various components like as Function libraries, Test data sources, Object details Other reusable modules.

With traditional manual testing the testers manually look out for defects in the software by following a written test plan consisting of sets of various test cases. It requires the tester to step into the shoes of a user and analyze the behavior of the website or mobile app, whether it is functionally in sync or it delivers a different and often erroneous behavior than expected.

Adapting API testing for a website using Excel, you're essentially organizing and documenting your testing process. This setup helps in managing test cases, tracking results, and analyzing data efficiently. Automated API Testing provides a streamlined, efficient way to verify the functionality, reliability, and performance of your APIs. With automated testing, you can ensure that your APIs meet quality standards and integrate seamlessly with your applications, all while reducing manual effort and accelerating your development cycle.
