What is Selenium?
Selenium is an open-source automation testing framework specifically designed for web applications. First released in 2004 by Jason Huggins, it has evolved into the industry standard for automated web testing, supporting multiple browsers, programming languages, and operating systems.
Unlike traditional testing tools, Selenium mimics real user interactions with web applications, allowing testers and developers to:
- Automate repetitive web testing tasks
- Execute tests across different browsers simultaneously
- Validate web functionality without manual intervention
- Create comprehensive test suites for continuous integration
