Support for context switching

[tmulry]

Hi-
I have searched through the code/issues, and although I see some references to context switching and hybrid apps, they do not appear to be supported by the code. I have patched the code(example below) for my own use.

module Appium::Capybara
  class Appium::Capybara::Driver
    def set_context context
      browser.set_context context
    end
  end
end

Has anyone tried to implement this? It seems fairly straightforward and works fine in iOS and selendroid, but I am running into an issue with chromedriver on sauce when I try to switch contexts. Is there any documented reason why the context methods haven't been implemented?

Edit: The chromedriver error is below. I don't get any error when I run this locally on a real device or run this request straight through the vanilla appium selenium driver.

Did not get session redirect from Chromedriver (Selenium::WebDriver::Error::UnknownError)
      ./common/appium.rb:9:in `set_context'

Thanks for bringing this up - the reason it's not in appium capybara is just that it hasn't been added yet; it'd be fine to add. As a workaround you could use the underlying ruby_lib methods directly as page.driver.appium_driver.available_context and page.driver.appium_driver.set_context.

I haven't seen the issue with Chromedriver; can you provide a repro case for that? Is it happening in a webview only?

I'd welcome a patch to add set_context and available_contexts to appium_capybara, or even suggestions as to what the methods should be.

The did not get session redirect is a common problem with chromedriver. It's not Ruby specific.

@bootstraponline , Yeah I did not see the full scope of that chromedriver issue at first. I will put together a pull request to add those context methods when I get some time.

FWIW, switching my caps to use appiumVersion="1.3.6" on all devices that use chromedriver seems to have resolved the context switching issue.

Issue appears resolved. If it's still broken, comment and let us know. Thanks!
