API testing has become an integral part of software quality assurance. Automating REST APIs ensures the robustness and reliability of web applications by validating backend functionality. In this blog, we will explore how Selenium and Postman can be used to automate REST APIs, providing both flexibility and scalability in your testing processes. Why Automate REST APIs? Automating REST APIs brings several benefits, including: Speed : Automated tests execute faster compared to manual testing. Accuracy : Minimizes human error in repetitive tasks. Efficiency : Allows simultaneous testing of multiple endpoints. Integration : Fits seamlessly into CI/CD pipelines. Key Concepts in REST API Automation Before diving into automation, let’s understand some key concepts: API Endpoint : A URL that specifies where an API resource is located. HTTP Methods : Common methods include GET, POST, PUT, DELETE. Status Codes : Responses like 200 (OK), 404 (Not Found), 500 (S...

1.  Introduction to REST API Testing 1.1. What is an API? An API (Application Programming Interface) defines the methods, protocols, and tools for building software applications. It specifies how different software components should interact with each other. In our social media application, the API provides a set of endpoints and rules for accessing and manipulating user profiles. The API documentation defines the available endpoints, the required parameters, the expected response format, and any authentication requirements. Developers can use this API to integrate social media features into their own applications. Table of Contents: 1. Introduction to REST API Testing      1.1. What is an API?      1.2.
