Answer 1

For test runtime in Capybara 2.2.4 version you can achieve this by doing

before do
  handle = Capybara.page.driver.current_window_handle
  Capybara.page.driver.resize_window_to(handle, height, width)
end

Or

before do   
  Capybara.page.current_window.resize_to(height, width)
end

If you get Capybara::NotSupportedByDriverError: Capybara::Driver::Base#current_window_handle YOU MUST CHANGE YOUR DRIVER FOR EXAMPLE USE JAVASCRIPT DRIVER!

before do   
  Capybara.page.current_window.resize_to(height, width)
end

scenario js: true do
  # your test here
end
