Is there a way to detect that I'm in a Selenium Webdriver page from Javascript

Question

I'd like to suppress the initialization of TinyMCE inside my tests and can do this easily if the Javascript can detect that I'm running inside a Selenium-automated page.

So, is there some JS code that I can use to detect the Selenium driver? Alternatively, how can I extend the userAgent string to include a pattern that I can detect from JS?

If it really matters, I'm running this through cucumber and capybara on Mac OS X.

Answer 1

1. Since webbriver automates normal browsers (just like iMacros), your website can not detect it directly.

2. You can easily append a string to the useragent:

This is easy with the Firefox Driver:

FirefoxProfile profile = new FirefoxProfile(); profile.addAdditionalPreference("general.useragent.override", "some UA string"); WebDriver driver = new FirefoxDriver(profile);

Answer 2

Since the question mentions Capybara, here's the equivalent code in Ruby:

profile = Selenium::WebDriver::Firefox::Profile.new
profile['general.useragent.override'] = "my ua string"

driver = Selenium::WebDriver.for :firefox, :profile => profile
