Mocking

  • timecop - A gem providing “time travel”, “time freezing”, and “time acceleration” capabilities, making it simple to test time-dependent code. It provides a unified method to mock Time.now, Date.today, and DateTime.now in a single call.
  • vcr - Record your test suite’s HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests. http://relishapp.com/vcr/vcr
