PageLoadTimes.feature

Feature: page load times

  Scenario: uncached page load time
    When I visit "http://www.google.com" without previously being there
    Then I should experience a load time below "2" seconds

  Scenario: cached page load time
    When I visit "http://www.google.com" with previously being there
    Then I should experience a load time below "0.8" seconds
