Firefox driver (gechodriver) for selenium 3.0

From selenium 3.0 on wards, we need to explicitly provide firefox driver (geckodriver) as firefox no longer provides default inbuilt driver.

If you will not provide the firefox driver explicitly & run as usual, then you will get exception –

Exception in thread “main” org.openqa.selenium.WebDriverException: Missing ‘marionetteProtocol’ field…


Exception in thread “main” “java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property;

set the system property as you do for chrome browser :

Download gechodriver releases  (chose for respective OS)
You can now run tests on all old and new versions of Firefox (like 46, 47 etc…)
