I see that there are three major drivers for IE&#12289;Firefox and Chrome&#65292;but Safari is not mentioned. Does WebDriver support web automation in Safari please?
I believe there is partial support for it. Do a search for "SafariDriver" or "Safari Driver".
Appears Safari is only supported in Selenium 1 commands, it can be done from Webdriver however:
A good rule of thumb is to never measure with your thumb.
