class RuboCop::Cop::RSpec::Capybara::CurrentPathExpectation
Checks that no expectations are set on Capybara's `current_path`.
The `have_current_path` matcher (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 (github.com/teamcapybara/capybara/blob/master/ README.md#asynchronous-javascript-ajax-and-friends) which ensures that preceding actions (like `click_link`) have completed.
@example
# 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/)
