We disabled caching entirely, because it sometimes led to unexpected
behavior in tests, and Qt 4.8 didn't behave the same as Qt 5.x.
However, this introduced issues:
* Selenium does perform caching, so capybara-webkit behaved differently
when switching drivers
* Without any caching, assets were sometimes requested twice for the
same page
This commit re-enables caching and attempts to improve the way we behave
on cached pages so that testing is less unpredictable. It adds tests to
ensure we continue to behave similarly to Selenium.
* This behavior changed in Capybara 2.4.
* Previously we would focus and send keypress events to readonly
elements. Now readonly elements are ignored, and a warning is emitted
by Capybara.
This adds support for the full Capybara 2.3.0 API. There are two known
incompatibilities:
* Selenium supports outerWidth and outerHeight, which we cannot, because we
dont' have an actual OS window.
* Selenium raises errors after interacting with a closed window. We focus the
next available window after closing.
This commit adds the following:
* Implement Driver#close_window
* Implement Driver#current_window_handle
* Implement Driver#maximize_window
* Implement Driver#open_new_window
* Implement Driver#no_such_window_error
* Implement Driver#resize_window_to
* Implement Driver#switch_to_window
* Implement Driver#window_size
* Implement Driver#go_back
* Implement Driver#go_forward
* Support change events when clearing a text input
* Support setting contentEditable elements
* Support window.close() in JavaScript
* Don't return text from hidden elements
* Skip Capybara specs which use outerWidth, outerHeight
* Don't use Qt object ownership to manage windows
