ActiveJobSpec

A test double of ActiveJob for RSpec.

Installation

Add this line to your application's Gemfile:

gem 'activejob_spec'

or

  group :development, :test do
    gem 'activejob_spec'
  end

Usage

Given this scenario

Given a payment
When I process
Then the payment has process queued

And I write this spec using the activejob_spec matcher

describe '#process' do
  before do
    ActiveJobSpec.reset!
  end

  it 'adds payment.process to the Payment queue' do
    payment.process
    expect(Payment).to have_queued(payment.id)

    # also possible with :once and :times methods
    # expect(Payment).to have_queued(payment.id).once
  end
end

And I see that the have_queued assertion is asserting that the Payment queue has a job with arguments payment.id and :process

And I take note of the before block that is calling reset! for every spec.

You can check the size of the queue in your specs too.

describe '#process' do
  before do
    ActiveJobSpec.reset!
  end

  it 'adds an entry to the Payment queue' do
    payment.process
    expect(Payment).to have_queue_size_of(1)
  end
end

Scheduled Jobs

Given this scenario

Given a payment
When I schedule a process
Then the payment has process scheduled

And I write this spec using the activejob_spec matcher

describe '#process' do
  before do
    ActiveJobSpec.reset!
  end

  it 'adds payment.process to the Payment queue' do
    payment.process

    expect(Payment).to have_scheduled(payment.id)
  end
end

And I might use the at statement to specify the time:

describe "#process" do
  before do
    ResqueSpec.reset!
  end

  it 'adds payment.process to the Payment queue' do
    payment.process

    # Is it scheduled to be executed at 2010-02-14 06:00:00 ?
    expect(Payment).to have_scheduled(payment.id).at(Time.mktime(2010,2,14,6,0,0))
  end
end

And I might use the in statement to specify time interval (in seconds):

describe '#process' do
  before do
    ResqueSpec.reset!
  end

  it 'adds payment.process to the Payment queue' do
    payment.process

    # Is it scheduled to be executed in 5 minutes?
    expect(Payment).to have_scheduled(payment.id).in(5 * 60)
  end
end

You can also check the size of the schedule:

describe "#process" do
  before do
    ResqueSpec.reset!
  end

  it "adds payment.calculate to the Payment queue" do
    payment.process

    expect(Payment).to have_schedule_size_of(1)
  end
end

(And I take note of the before block that is calling reset! for every spec)
