How do I set options for the Selenium MS Edge driver in ruby?

Question

I am trying to open a browser with the Selenium::WebDriver::Edge::Driver on Windows. I am able to open the browser but my session immediately crashes with this error:

unknown command: Cannot call non W3C standard command while in W3C mode 
(Selenium::WebDriver::Error::UnknownCommandError)

How would I turn off W3C mode in selenium ruby? I have tried to follow the docs here by doing:

webdriver_options = Selenium::WebDriver::Edge::Options.new(opts: {w3c: false})

before instantiating the webdriver. However this does not seem to make a difference - I suspect I am setting the options wrong. Has anyone seen this issue before? Thanks.

Answer 1

1. verify if your browser is up to date
2. Start > Settings > System > About; - and verify OS build
3. Download last driver: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
4. Unzip las version on: C:\\Ruby23-x64\\bin;

5. If you are using capybara, try this:

   Capybara.register_driver :selenium do |app|

   Capybara::Selenium::Driver.new(app, :browser => :edge)

   end

Answer 2

If you're using Edge Chromium, I think the options are like the Chrome's. You could refer to this thread and add the following code then pass it into the driver:

capabilities = { "edgeOptions" => {'w3c' => false} }
