Overview

The Window class represents a browser window.

You can get an instance of the class by calling either of:

Note that some drivers (e.g. Selenium) support getting size of/resizing/closing only

current window. So if you invoke such method for:

* window that is current, Capybara will make 2 Selenium method invocations
  (get handle of current window + get size/resize/close).
* window that is not current, Capybara will make 4 Selenium method invocations
  (get handle of current window + switch to given handle + get size/resize/close + switch to original handle)
