ChromeDriver error “unknown error: cannot get automation extension”

Question

Since the 7th of February all my tests are failing with the same error; the log entry reads:

RESPONSE MaximizeWindow unknown error: cannot get automation ext         


        

Answer 1

This could probably because the environment where you are running the tests is blocking all the third party extensions in chrome browser. Give it a try with disabling the extensions.

something like below:

ChromeOptions o = new ChromeOptions();
o.addArguments("disable-extensions");
o.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(o);
