API Testing

APIs, or Application Programming Interfaces, play a crucial role in the modern software industry by facilitating communication between different systems and services, as exemplified by their use in flight booking applications. With over 90% of developers utilizing APIs and the API management market projected to grow significantly, understanding APIs, particularly REST and SOAP, is essential. REST is an architectural style using lightweight JSON, favored for web and cloud applications due to its simplicity and performance, while SOAP is a protocol that employs XML for high-security enterprise applications. API testing is a critical process involving the validation of API functionality, reliability, performance, and security through various methods and tools like Postman and testRigor, which offer automation and ease of use. Testing involves understanding API functionality, setting up the testing environment, and executing test cases for different HTTP methods and scenarios, including security testing, to ensure robust API services.
