What is Selenium? An Introduction for Beginners

Selenium is an open-source testing framework used for automating web applications. It allows testers and developers to write test scripts in various programming languages like Python, Java, C#, and JavaScript to interact with web browsers and perform automated testing.


Why Use Selenium?

Cross-Browser Testing: Supports multiple browsers like Chrome, Firefox, Edge, and Safari.


Multiple Programming Languages: Works with Java, Python, C#, and more.


Open-Source & Free: No licensing costs.


Supports Parallel Execution: Run multiple tests at the same time.


Integration with Other Tools: Works with TestNG, JUnit, and CI/CD tools like Jenkins.


Selenium Components

Selenium WebDriver: Automates web application testing across browsers.


Selenium IDE: A browser extension for record-and-playback testing.


Selenium Grid: Allows parallel execution on multiple machines.


How Does Selenium Work?

Selenium interacts with web elements like buttons, text fields, and links by locating them using element locators such as ID, Name, XPath, and CSS selectors. It then performs actions like clicking, entering text, or verifying content.


Getting Started with Selenium

To begin using Selenium, follow these steps:


Install a programming language (e.g., Python or Java).


Download and install the Selenium WebDriver.


Set up a web driver for your preferred browser.


Write test scripts using Selenium commands.


Conclusion

Selenium is a powerful tool for web automation testing. It simplifies testing processes, improves efficiency, and ensures high-quality web applications. Whether you're a beginner or an experienced tester, learning Selenium can be a valuable skill in software testing.

Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...
