Is Selenium for API testing?

No, Selenium is not primarily used for API testing but it is used for Automation on web browser interactions to test web applications, so it is not typically used for API testing. API testing involves testing the functionality, performance, and reliability of application programming interfaces (APIs) directly, without interacting with a web browser.

For API testing, other tools and frameworks are more commonly used, such as:

1. Postman: Postman is a popular API testing tool that allows users to create, test, and automate API requests. It provides a user-friendly interface for sending HTTP requests, inspecting responses, and validating API behavior.
2. REST Assured: REST Assured is a Java library designed to automate REST API testing. It provides a fluent API for making HTTP requests, validating responses, and writing test cases in Java.
3. SoapUI: SoapUI is an open-source tool for testing SOAP and REST APIs. It offers features for creating, executing, and managing API tests, including support for functional, load, and security testing.
4. JMeter: Apache JMeter is a performance-testing tool that can also be used for API testing. It allows users to simulate heavy loads on APIs, measure performance metrics, and identify bottlenecks or performance issues.

While Selenium is not typically used for API testing, it is an essential technical skill for automating web browser interactions and testing web applications. Depending on your role and responsibilities, you may find value in learning both Selenium for web UI testing and other tools/frameworks for API testing to cover a broader range of testing scenarios and requirements.
