Challenges with Testing Background Jobs in Ruby on Rails 7 Using RSpec and ActiveJob

I've tried everything I can think of but I'm working on a personal project and I'm performance testing and Quick question that's been bugging me - This might be a silly question, but Currently developing a Rails 7 application that relies heavily on background jobs for processing user uploads... As part of the QA process, I'm trying to write automated tests for these jobs using RSpec along with ActiveJob. The challenge arises when the jobs execute asynchronously and I need to ensure they complete successfully before asserting their outcomes. To tackle this, I've utilized the built-in test helpers for ActiveJob, but I'm not entirely sure if I'm using them correctly. Here's what I've implemented so far: ```ruby RSpec.describe MyUploaderJob, type: :job do include ActiveJob::TestHelper it 'processes the file upload' do perform_enqueued_jobs do MyUploaderJob.perform_later(upload) end expect(FileProcessingService).to have_received(:call).with(upload) end end ``` This approach seems straightforward, but I encounter a situation where the job sometimes fails to complete in the testing environment, leading to flaky tests. I've also tried using `perform_now` instead of `perform_later`, but it doesn't suit the scenario where I want to test the queueing functionality. Another avenue I've explored is adjusting the queue adapter in my `test.rb` file to `:inline`, which I thought would execute jobs immediately. However, this change didn't resolve the issue as expected. Here's the relevant part of my configuration: ```ruby # config/environments/test.rb config.active_job.queue_adapter = :inline ``` I’m curious if anyone has insights into best practices for testing background jobs in Rails 7, especially when dealing with scenarios that are not consistently reproducible. Are there alternative approaches or patterns that could lead to more reliable tests? Any advice on managing job dependencies within these tests would be greatly appreciated. What am I doing wrong? For context: I'm using Ruby on Linux. I'm using Ruby 3.9 in this project. What are your experiences with this? I'm on CentOS using the latest version of Ruby.
