How to use Firefox WebDriver with Mozilla GechoDriver?

If you are using the Firefox WebDriver with the Selenium Python API, you need to make 'geckodriver' executable available in PATH environment variable.

1. Include path name of the 'chromedriver' executable in PATH environment variable.

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

C:\fyicenter>set path=\fyicenter\selenium\geckodriver;%path%

2. Run the FirefoxTest.py again.

C:\fyicenter> python FirefoxTest.py 
Traceback (most recent call last):
  File "FirefoxTest.py", line 2, in <module>
    driver = Firefox()
  
  File "C:\Users\fyicenter\AppData\Local\Programs\Python\Python37-32
    \lib\site-packages\selenium\webdriver\common\service.py", line 174, 
  in startstdin=PIPE)
   ...
selenium.common.exceptions.SessionNotCreatedException: Message: 
Unable to find a matching set of capabilities
