ruby-on-rails - 如何使用 rspec 测试（Bean）Stalker？

Question

我有一个名为jobs.rb的文件

require File.expand_path("../environment", __FILE__)

job "do.stuff" do |args|
  $value = 10
end

然后我有这个名为jobs_spec.rb的规范文件

require File.expand_path("../../spec_helper", __FILE__)

describe "some beanstalk jobs" do
  it "should work" do

    # What to do here?

    $value.should eq(10)
  end
end

如何测试$value变量？

Answer 1

我会检查图书馆本身如何运行它的测试：

请记住，这是使用 Test::Unit，但是您可以在 Rspec 中应用相同的技术。

Answer 2

您必须在运行测试的机器上运行 beanstalkd。

require "Stalker"

describe Stalker, "job" do
  before :all do
    # Make sure beanstalkd is running
    if `pgrep beanstalkd` == ""
      raise "PRECONDITION NOT MET: beanstalkd not running"
    end

    module Stalker
      def log(msg); end
      def log_error(msg); end
    end
  end

  before :each do
    Stalker.clear!
    $result = -1
    $handled = false
  end

  it "enqueue and work a job" do
    val = rand(999999)
    Stalker.job('my.job') { |args| $result = args['val'] }
    Stalker.enqueue('my.job', :val => val)
    Stalker.prep
    Stalker.work_one_job
    val.should == $result
  end
end
