I'm trying to run a webdriver test in python on a mac (El Capitan 10.11.5). I was successful running the same test with FirefoxDriver (using FF 46, before marionette). When I try doing the same using chromedriver 2.22 or 2.20, I get a strange result - the test runs and passes, but I see no window doing it.
I'm not trying to run a headless browser - I want to see the browser.
Any ideas what's going on here?
I'm using python 2.7.11, selenium 2.53.5.
