Frequently Asked Questions

API test automation involves the creation of automated test scripts that simulate different types of API requests and responses to validate their functionality, reliability, and performance. This helps to ensure that APIs are working as expected and meet the requirements of the software application being developed, while also reducing the risk of human error and increasing testing efficiency.
