Questions :-

• Why selenium opens browser on the basis of executable driver setting?
• Is in both case selenium behavior is correct?
• If correct then why we have separate driver class name like FirefoxDriver , InternetExplorerDriver , ChromeDriver etc?

Answer 1

The selenium project just attempts to launch the executeable and the request a new session from it. The problem here is that chromedriver readily accepts the new session request for "firefox", but it shouldn't.

It is a bug, actually, there was the thread regarding this on git hub for selenium board. If we pass chromedriver.exe for webdriver.gecko.driver , it works and opens chrome browser

Hope it helps.
