Pattern: Expectation on current_path
Issue: -
Checks that no expectations are set on Capybara's current_path.
The have_current_path matcher (http://www.rubydoc.info/github/teamcapybara/capybara/master/Capybara/RSpecMatchers#have_current_path-instance_method) should be used on page to set expectations on Capybara's current path, since it uses Capybara's waiting functionality (https://github.com/teamcapybara/capybara/blob/master/README.md#asynchronous-javascript-ajax-and-friends) which ensures that preceding actions (like click_link) have completed.
# bad
expect(current_path).to eq('/callback')
expect(page.current_path).to match(/widgets/)
# good
expect(page).to have_current_path("/callback")
expect(page).to have_current_path(/widgets/)
