When you need to config the environment to run selenium grid, your code run correctly but the browsers do not appear, you should review the following below:
1. use version stand alone 2.53 voi selenium 2.53
2. Latest Release: ChromeDriver 2.31. Supports Chrome v58-60 ok!
3. Ko Dùng port 4444 mà dùng port 9090
4. I found the solution in a bit of a convoluted way. The first step was
-. Changing the host file entry for the local host.
-. Removing the json dll from the Project References (don’t know if it has any bearing on the issue)
-. Set the IE security settings to the lowest.
-. In code, use the DesiredCapabilities.SetCapability(“ignoreProtectedModeSettings”) construct while instantiating the InterneyWebDriver object.
