RSpec、ActiveJob、Sidekiq：在测试其他工作时避免工作被解雇？

Question

我正在测试 ParseProjectsJob，它会在完成后触发 PushProjectJob。我需要避免这种行为，这就是 ParseProjectsJob 的样子：

请记住，我正在使用 Sidekiq::Testing.inline！在我的 parse_project_spec.rb 中。

# [...] = Omitted code.

[...]
class ParseProjectsJob < ActiveJob::Base
  [...]
  def perform
      [...]
      PushProjectJob.set(wait: to_wait.second).
        perform_later({:project => onvia_project, :budget_years => @project_budget_years})
      [...]
  end
  [...]
end
[...]

所以我在我的 parse_projects_job_spec.rb 中进行了尝试：

allow_any_instance_of(PushProjectJob).to receive('perform_later') { true }

输出： PushProjectJob 未实现#perform_later

也试过了：

allow_any_instance_of(PushProjectJob).to receive('perform') { true }

它通过了，但工作还是被解雇了。

最后我试过了：

allow_any_instance_of(PushProjectJob).to receive_message_chain('set.perform_later') { true }

输出：PushProjectJob 没有实现#set

parse_projects_job_spec.rb：

require 'rails_helper'
require 'sidekiq/testing'
require 'fileutils'

RSpec.describe ParseProjectsJob, type: :job do
  Sidekiq::Testing.inline!

  let(:perform_job) {
    allow(PushProjectJob).to receive_message_chain('set.perform_later') { true }
    exitable { ParseProjectsJob.perform_later }
  }

  let(:download_valid_file) {
    FileUtils.cp 'spec/fixtures/projects_sheets/valid_file.xlsx',
      Rails.root.join('public', 'downloads', 'projects_sheet')
  }

  describe "#perform" do
    it "parse and push all projetcs inside a sheet" do
      download_valid_file
      perform_job
      expect(Job.projects_parse.with_success.last.
        actions.last.message).
        to eql('No more files to parse, the job is done.')
    end
  end
end

Answer 1

您的最后一次尝试接近解决方案，只需将allow_any_instance_of 更改为allow：

allow(PushProjectJob).to receive_message_chain('set.perform_later') { true }

Answer 2

这将起作用：

let(:perform_job) {
  interval = double
  allow(PushProjectJob).to receive('set') { interval }
  allow(interval).to receive(:perform_later) { true }
  exitable { ParseProjectsJob.perform_later }
}
