如何在Rails + Active Job中测试松弛集成

Question

我正在使用Rails Active Job对松弛通知进行排队。调度程序是sidekiq。一切正常，但不知道如何为Rails Active Job编写测试。我正在使用slack-notifier gem使用其Web挂钩与Slack连接。

在user.rb

def send_slack!
  text = "New user #{first_name} #{last_name} has signed up"
  channel = "#pltf_signup"
  webhook_url = ENV["SLACK_SIGNUP_WEBHOOK_URL"]

  NotifiableSlackJob.perform_later(webhook_url: webhook_url, text: text, channel: channel) if Rails.env.production?
end

在notifiable_slack_job.rb

class NotifiableSlackJob < ApplicationJob
  queue_as :default 

  def perform(webhook_url:, text:, username: "BOT", channel:, icon_emoji: ":smile_cat:")
    notifier = Slack::Notifier.new webhook_url, username: username, channel: channel, icon_emoji: icon_emoji
    notifier.ping text
  end
end

到目前为止，我写的测试是notifiable_slack_job_spec.rb

require 'rails_helper'

RSpec.describe NotifiableSlackJob, type: :job do
  describe "#perform" do
    it "sends a Slack message" do      
      NotifiableSlackJob.perform_now(webhook_url: ENV["SLACK_SIGNUP_WEBHOOK_URL"], text: "Hi", channel: '#pltf_signup')
    end
  end
end

我使用的测试框架是RSpec。 谢谢。
