ResqueSpec

A simple RSpec and Cucumber matcher for Resque.enqueue and Resque.enqueue_at (from ResqueScheduler), loosely based on http://github.com/justinweiss/resque_unit.

This should work with Resque v1.6.0 and up and RSpec v1.3.0 and up.

Install

Install the gem

% gem install resque_spec

And update your Gemfile (Not using bundler? Do the necessary thing for your app's gem management)

group :test do
  gem 'resque_spec'
end

Resque with Specs

Given this scenario

Given a person
When I recalculate
Then the person has calculate queued

And I write this spec using the resque_spec matcher

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

  it "adds person.calculate to the Person queue" do
    person.recalculate
    Person.should have_queued(person.id, :calculate)
  end
end

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

And I might write this as a Cucumber step

Then /the (\w?) has (\w?) queued/ do |thing, method|
  thing_obj = instance_variable_get("@#{thing}")
  thing_obj.class.should have_queued(thing_obj.id, method.to_sym)
end

Then I write some code to make it pass:

class Person
  @queue = :people

  def recalculate
    Resque.enqueue(Person, id, :calculate)
  end
end

ResqueScheduler with Specs

Given this scenario

Given a person
When I schedule a recalculate
Then the person has calculate scheduled

And I write this spec using the resque_spec matcher

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

  it "adds person.calculate to the Person queue" do
    person.recalculate
    Person.should have_scheduled(person.id, :calculate)
  end
end

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

And I might write this as a Cucumber step

Then /the (\w?) has (\w?) scheduled/ do |thing, method|
  thing_obj = instance_variable_get("@#{thing}")
  thing_obj.class.should have_scheduled(thing_obj.id, method.to_sym)
end

Then I write some code to make it pass:

class Person
  @queue = :people

  def recalculate
    Resque.enqueue_at(Time.now + 3600, Person, id, :calculate)
  end
end

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
