You can add this to the shortcut of the chrome browser, in the Target portion:

–test-type

This would disable any warning messages.Not the best solution, but it works.


For a chrome version of 58.0.3029.110, You should use Chrome.driver of 2.28 version. Download driver from http://chromedriver.storage.googleapis.com/index.html?path=2.28/

Note: If you want to download other chromedriver of other version then change version number in the above url.

Happy learning


I had this issue recently. I found out I was using a 32-bit chromedriver for a 64-bit Mac. So I simply replaced the chromedriver with a 64-bit chromedriver from https://chromedriver.storage.googleapis.com/index.html?path=2.25/ and the error was gone.
