REST API Automation Testing from Scratch - REST Assured Java - Understanding GET, POST, PUT DELETE, HTTP, and CRUD Opera

The video tutorial provides an overview of APIs, focusing on REST and SOAP standards. It emphasizes the importance of API testing, especially for integration and preventing bugs. The tutorial explains REST API components, including endpoints and HTTP methods like GET, POST, PUT, and DELETE. It concludes with practical steps for API testing using tools like Postman.

What is a key reason for the popularity of REST APIs over SOAP APIs in modern web applications?

• REST APIs do not require internet connectivity.

• REST APIs are easier to build and maintain.

• SOAP APIs are not compatible with modern browsers.

• REST APIs are more secure than SOAP APIs.
