Selenium 3 geckodriver automation tests

Selenium 3 stopped support for FirefoxDriver , It will work only up to firefox version 46.

To work with latest firefox browsers, you have to use Gecko Driver

Download latest geckodriver from https://github.com/mozilla/geckodriver/releases

Then set system property “webdriver.gecko.driver” using –
System.setProperty(“webdriver.gecko.driver”,
“pathToGeckoDriver\\geckodriver.exe”);


if (SystemUtils.IS_OS_WINDOWS) {

System.setProperty("webdriver.gecko.driver",

"drivers\\geckodriver.exe");

} else if (SystemUtils.IS_OS_LINUX) {

System.setProperty("webdriver.gecko.driver", "drivers/geckodriver");
}
Then simply call 
WebDriver driver = new FirefoxDriver();

driver.get();
