Running Rake tasks from your test environment

Running Rake tasks from a spec

This will try to find all the rake tasks defined in the lib/tasks directory and run them. Note that some tasks might need arguments and will fail. I want to keep this example short so dealing with that is left as an exercise for the intern.

rake_rails_spec.rb

require_relative '../spec_helper'
require 'rake'

Dir.glob(Rails.root.join('lib/tasks/**/*.rake')).each do |rakefile|
  begin
    load rakefile
  # There could be an RSpec task which will throw a NameError. Which is a
  # good thing, otherwise we would invoke this spec recursively.
  rescue NameError => exception
    puts '[!] ' + exception.message
  end
end

describe "Rake tasks" do
  Rake.application.tasks.each do |task|
    it "should run `rake #{task.name}'" do
      task.invoke
    end
  end
end

# Load the standard Rails tasks so other tasks can use the :environment
# task. We do this after defining the specs because otherwise we would
# invoke all Rails tasks (like db:drop).
Rails.application.load_tasks

rake_spec.rb

require_relative '../spec_helper'
require 'rake'

Dir.glob(Rails.root.join('lib/tasks/**/*.rake')).each do |rakefile|
  begin
    load rakefile
  rescue NameError => exception
    puts '[!] ' + exception.message
  end
end

describe "Rake tasks" do
  Rake.application.tasks.each do |task|
    it "should run `rake #{task.name}'" do
      task.invoke
    end
  end
