Windows 10 is now available on TestingBot to use during both manual and automated testing (Selenium WebDriver). This is the latest OS version available from Microsoft, with all installed updates, running the most recent version of Microsoft Edge.
Thanks to the work of Microsoft, it is possible to run Selenium WebDriver tests on Microsoft Edge.
When you log in on TestingBot, you can now run cross browser tests on Windows 10. Simply go to "Manual Testing", choose Windows 10 and pick any browser (IE11, Microsoft Edge, Chrome, Firefox, ...). Seconds later you'll be controlling your own browser in our cloud, with your mouse and keyboard.
To run automated Selenium tests, please see the various possible desired capabilities to run on Windows 10.
