API testing automation is a crucial aspect of software development that simplifies the complex task of managing multiple test cases, decreases time-to-market and improves scalability by enhanced test case management. It offers the best ROI according to Mike Cohn’s book, "Succeeding with Agile: Software Development Using Scrum". The recent pandemic has emphasized the importance of cloud-based APIs, making API testing automation essential for organizations that want to enhance cloud-based APIs or improve the efficiency of third-party integrations. A well-planned API testing automation strategy is critical, involving the development of an automation plan, choosing the right test environment, designing tests, and executing and analyzing the results. The success of API testing automation depends on a good framework, test environment configuration, and execution approach, with tools like RapidAPI, Postman, SoapUI, Apigee, and JMeter being popular choices for automating API testing.
