ndbroadbent / sidekiq_health_check_job.rb

Last active June 10, 2019 19:48

An RSpec test that ensure that the Sidekiq worker can actually boot without crashing, and runs a real test job from Redis

	# frozen_string_literal: true

	# spec/jobs/worker_health_check_job_spec.rb starts a Sidekiq worker process

ndbroadbent / sidekiq_sanity_check_v3.sh

Created June 10, 2019 15:39

sidekiq_sanity_check_v3 - Revert to using --daemon flag, and use a lightweight Ruby script to push the job to Redis

	#!/bin/bash
	set -e
	if [ -f .env ]; then spring stop; fi

	# This script is run in the CI build. It requires a REDIS_URL variable,
	# and runs a test job through the WorkerHealthCheckJob.
	# I added this check after I accidentally pushed a change that caused the sidekiq
	# workers to crash on boot. The jobs were well-tested, but the actual
	# sidekiq config had an error inside a #configure_server block, so the code
	# only crashed when I started an actual Sidekiq worker process.
