Windows 10 is out, this time, with new Edge browser to replace IE. Yes, Microsoft will provide WebDriver support for Edge, it is called Microsoft WebDriver. For testers who can't wait, you can try out in TestWise v4.3 with experimental Edge support (bundled selenium-webdriver 2.47.1).
Just change the driver type to :edge
@driver = Selenium::WebDriver.for(:edge)
Yes, I think TestWise looks better in Windows 10 with thin borders.
