When basing logic on the current time its helpful for testing to have a stable
time. A time that does not change. Rails has a module
ActiveSupport::Testing::TimeHelpers that was added in Rails 4.2 to provide methods that manipulate the time during testing.
travel_to(Time.parse("2017-01-19")) do puts Time.now.strftime(:date) end puts Time.now.strftime(:date)
The above code outputs
2017-05-02 (the current date). A fun
way to time travel in modern ruby.
