How to use Firefox WebDriver with Mozilla GechoDriver?

If you are using the Firefox WebDriver with the Selenium Java API, you need to set the webdriver.gecko.driver system property to the path to the Mozilla GechoDriver driver as shown below.

1. Make sure that you have Mozilla GechoDriver WebDriver Server installed:

C:\fyicenter>dir \fyicenter\selenium\geckodriver
        14,478,647 geckodriver.exe

2. Set the webdriver.chrome.driver system property to the GechoDriver server program path and run the test again.

C:\fyicenter> java -classpath \
   .;\fyicenter\selenium\java\client-combined-3.141.59.jar;\
   \fyicenter\selenium\java\libs\guava-25.0-jre.jar;\
   \fyicenter\selenium\java\libs\okhttp-3.11.0.jar;\
   \fyicenter\selenium\java\libs\okio-1.14.0.jar;\
   \fyicenter\selenium\java\libs\commons-exec-1.3.jar \
   -Dwebdriver.gecko.driver=\fyicenter\selenium\geckodriver\geckodriver.exe \
   FirefoxTest

As you can see, we are getting a diffrent error, which is caused by version compatibility issues of Selenium Firefox WebDriver, Mozilla GechoDriver, and MozillaFirefox. See next tutorial on how to fix it.
