This gem was born out of a desire to test the schedule for tasks being scheduled with Whenever. Not to test if Whenever can generate the proper CRON schedule, but to test whether I can generate the proper config/schedule.rb. It turns out I can't sometimes.

Add this to you gemfile:

gem "shoulda-whenever", "~> 0.0.2"

Create a new schedule to be tested at config/schedule.rb (or anywhere really, but for the sake of the README, that's where it is):

every :friday, at: "12:00 PM" do
  runner "Notifier.send_team_lunch_email"
end

Create a new test file for testing your schedule, perhaps something like spec/schedule_spec.rb:

describe "Schedule" do
  include Shoulda::Whenever

  let(:whenever) { Whenever::JobList.new(file: File.join(Rails.root, "config", "schedule.rb").to_s) }

  it "sends out the team lunch reminder email every friday at noon" do
    expect(whenever).to schedule("Notifier.send_team_lunch_email").every(:friday).at("12:00 PM")
  end
end
