Selenium Webdriver (FirefoxDriver)
- by Samareri
Hey all,
I'm using Selenium Webdriver to do some robottesting. Since some functions appear to only work in Firefox, I'm obligated to use Firefoxdriver.
Now and then, something weird happens. Starting up te driver
driver = new FirefoxDriver();
driver.get(URL);
gets firefox to startup but not to go to the specified url. The strange thing is that it works on another computer with the same preferences set in Firefox. I solved this problem once by changing to another version of firefox, but this time this doesn't do the trick for me, it did however worked for the other developers. Yes, the error started for all developers on the same time, same day...
My first question is: is it a firefox problem or Webdriver problem.
Second question: how is it possible that it works on other pc's?
Any help would be very appreciated
Thanks
