What is Selenium? Why do we use Selenium for Automation?What is the relevance of Selenium in automation testing using Python?
Selenium is an open-source tool that automates web browser actions across Chrome, Firefox, Safari, and Edge. It offers components such as WebDriver, Grid, and IDE to enable cross‑browser testing and parallel execution. When paired with Python, Selenium provides a concise, flexible framework that integrates with CI/CD pipelines and data‑driven testing.
- ▪Selenium WebDriver communicates directly with browsers via drivers like ChromeDriver and GeckoDriver.
- ▪Selenium Grid allows simultaneous test execution on multiple machines, operating systems, and browsers.
- ▪Selenium IDE is a browser extension for recording and replaying actions without coding.
- ▪Python’s simple syntax and libraries like pytest, pandas, and requests make Selenium tests easy to write, maintain, and extend for both testing and web scraping.
