def self.before
  monkeypatch_capybara if defined?(Capybara)
end

.monkeypatch_capybara ⇒ Object

Shunt Capybara’s after filter from before Pry::rescued to after.

The after filter navigates to ‘about:blank’, but people debugging tests probably want to see the page that failed.

      def reset_sessions!; end
    end

    after_filters << Capybara.method(:reset_sessions_after_rescue!)
  end
end

.run(example) ⇒ Object

Run an Rspec example within Pry::rescue{ }.

Takes care to ensure that ‘try-again` will work.
