API Testing
API testing is a software testing practice that focuses on verifying the functionality, reliability, performance, and security of application programming interfaces (APIs). It involves sending requests to API endpoints and validating responses against expected results, ensuring that APIs behave correctly under various conditions. This type of testing is crucial for modern applications that rely on APIs for communication between different software components.
Developers should learn API testing to ensure the robustness and reliability of their applications, especially in microservices architectures or when integrating third-party services. It is essential for catching bugs early in the development cycle, validating data exchange, and maintaining API contracts, which helps prevent integration issues and improves overall software quality. Use cases include testing RESTful APIs, GraphQL endpoints, and SOAP web services in web, mobile, and backend applications.
