Selenium WebDriver is a widely-used open-source automation framework that facilitates interaction with web pages through methods like isDisplayed(), isEnabled(), and isSelected(). These methods help testers verify the presence, visibility, and state of web elements, ensuring that test cases are accurately executed without false failures. The isDisplayed() method checks if elements like text boxes are visible on a page, while isEnabled() determines if an element is interactive, and isSelected() confirms if elements like checkboxes are selected. Implementing these methods within automated tests can prevent errors caused by missing or improperly loaded elements, especially when combined with tools such as LambdaTest for cross-browser testing. Each method returns a Boolean value, allowing testers to programmatically handle element states and improve the reliability of their test automation framework.
