在rspec中使用ActiveJob执行挂起作业

Question

我有这个代码用Rspec测试ActiveJob和ActionMailer我不知道如何真正执行所有排队的工作

describe 'whatever' do
  include ActiveJob::TestHelper

  after do
    clear_enqueued_jobs
  end  

  it 'should email' do
    expect(enqueued_jobs.size).to eq(1)
  end
end

Answer 1

以下是我解决类似问题的方法:

# rails_helper.rb
RSpec.configure do |config|
  config.before :example, perform_enqueued: true do
    @old_perform_enqueued_jobs = ActiveJob::Base.queue_adapter.perform_enqueued_jobs
    @old_perform_enqueued_at_jobs = ActiveJob::Base.queue_adapter.perform_enqueued_at_jobs
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = true
    ActiveJob::Base.queue_adapter.perform_enqueued_at_jobs = true
  end

  config.after :example, perform_enqueued: true do
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = @old_perform_enqueued_jobs
    ActiveJob::Base.queue_adapter.perform_enqueued_at_jobs = @old_perform_enqueued_at_jobs
  end
end

然后在规格中我们可以使用:

it "should perform immediately", perform_enqueued: true do
  SomeJob.perform_later  
end

正确的测试方法是检查排队作业的数量,如示例所示,然后分别测试每个作业.如果您想进行集成测试,可以尝试perform_enqueued_jobs帮助:

describe 'whatever' do
  include ActiveJob::TestHelper

  after do
    clear_enqueued_jobs
  end  

  it 'should email' do
    perform_enqueued_jobs do
      SomeClass.some_action
    end
  end

end
