RSpec::Timecop

RSpec extension for controlling time within examples.

Installation

Add this line to your application's Gemfile:

gem 'rspec-timecop'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rspec-timecop

Usage

In a RSpec example you can use the timecopped method to freeze time for the subject of the example:

class Foobar
  def self.hi
    OtherObject.time_check(Time.now)
    'hi'
  end
end

describe Foobar do
  let(:now) { Time.now }
  before do
    expect(OtherObject).to receive(:time_check)
      .with(now)
  end

  describe 'without the helper' do
    subject do
      result = nil
      Timecop.freeze(now) { result = Foobar.hi }
      result
    end
    it { should eq('hi') }
  end

  describe 'with the helper' do
    subject { timecopped(now) { Foobar.hi } }
    it { should eq('hi') }
  end
end

Without Timecop.freeze the value for Time.now being passed into ObjectOther#time_check could not be consistently checked. And using #timecopped hides away example how Timecop.freeze is used so that we can see the subject call more clearly.
