Open a URL

WebDriver driver = new ChromeDriver();
driver.get("https://shopease.example.com");               // waits until the page load event
driver.navigate().to("https://shopease.example.com/cart"); // same thing, keeps history for back/forward

• get() waits for the page to finish loading (document ready state "complete") before the next line runs.
• Always use the full URL with https://. driver.get("shopease.example.com") fails with InvalidArgumentException: invalid argument.

WebDriver is an interface; ChromeDriver, FirefoxDriver, EdgeDriver are classes that implement it. Declaring the variable as WebDriver lets you switch browsers by changing one line.
