Question

As seen below, we establish a WebDriver reference variable called 'driver.' What exactly is the purpose of proceeding in this manner?

Answer 1

WebDriver driver = new FirefoxDriver();

instead of creating

FirefoxDriver driver = new FirefoxDriver();

We may use the same driver variable to work with any browser we want, such as IEDriver, SafariDriver, and so on if we construct a reference variable of type WebDriver.
