Prioritize stable attributes like ID or Name . Avoid long, absolute XPaths (e.g., /html/body/div[1]/... ) which break if the page structure shifts even slightly. Selenium Design Patterns and Best Practices

Useful for multi-browser testing. A "Driver Factory" can initialize the correct driver (Chrome, Firefox, Edge) based on a configuration file, keeping the test initialization clean and centralized. Core Best Practices for Stability Use a Selenium Grid to run tests simultaneously

Never use Thread.sleep() , as it forces a script to wait for a fixed duration regardless of the page state. Instead, use Explicit Waits to pause execution until a specific condition—like an element becoming clickable—is met, significantly reducing execution time. Avoid long, absolute XPaths (e

An extension of POM where methods return the page object itself (or the next page object). This allows for "method chaining," creating readable, English-like test scripts: loginPage.enterUser("admin").enterPass("123").clickLogin(); .
