Software development is constantly changing, and APIs (Application Programming Interfaces) are the key to seamless communication and data exchange between applications and services. APIs become more complex, necessitating rigorous testing to ensure functionality, security, and performance. API testing is now essential to the software development lifecycle, ensuring that APIs meet modern application needs and provide a great user experience. Understanding API Testing Types API testing includes many test types that cover API functionality and performance. This includes: 1. Functional Tests Functional testing verifies that API endpoints respond correctly to input parameters and scenarios. It ensures API functionality. 2. Performance Tests Performance testing checks the API's responsiveness and capacity to handle high request volumes. For the API to scale to real-world demands, this is essential. Third, security testing Security testing assesses API resilience to vulnerabilities and un...
