API Testing

API testing is a crucial practice in modern software development that focuses on verifying the functionality, performance, reliability, and security of application programming interfaces (APIs). Since APIs act as the communication bridge between different systems and services, testing them thoroughly ensures that data exchange is smooth, accurate, and secure.

To streamline the process, teams often use specialized API testing software or an API testing framework – tools like Postman, SoapUI, or REST Assured – that simplify the creation, execution, and automation of tests. These tools also support different API testing methods, such as REST, SOAP, and GraphQL, enabling QA teams to test efficiently across diverse architectures.
