Rails: How to correctly execute an ActiveJob within a test using inline adapter?

Question

I have the following test:

require "test_helper"

class DisbursementGenerationTest < ActionDispatch::IntegrationTest
  test "disburse test orders" do
    puts "Performing job..."
    Merchant.all.each do |merchant|   
      DisburseJob.perform_later(merchant)      
    end
    puts "Job performed"
    sleep 10
    assert_equal 2, Disbursement.count
  end
end

In the /config/environment/test.rb I set the ActiveJob queue adapter to inline:

Rails.application.configure do
  config.active_job.queue_adapter = :inline

The Job in the test is not executed at all. I see output from both puts statements, but job is not running. I have checked there are 2 merchant objects as expected. In Dev environment I use sidekiq as a job backend and it executes jobs fine both from rails console manually and also scheduled jobs within an app.

How to correctly execute ActiveJob within a test?

I have executed the test and expected the job to run twice (once for each merchant object). The job has not executed at all.

For testing, you should set the queue adapter to test:

  config.active_job.queue_adapter = :test

And then you can execute the jobs with the perform_enqueued_jobs:

class DisbursementGenerationTest < ActionDispatch::IntegrationTest
  test "disburse test orders" do
    Merchant.all.each do |merchant|   
      DisburseJob.perform_later(merchant)      
    end

    perform_enqueued_jobs

    assert_equal 2, Disbursement.count
    assert_performed_jobs 2
  end
end
