Web apps often move long-running processes (such as delivering email) out of the request/response cycle into a queue of background jobs. A worker process then picks up those jobs from the queue and runs them in the background.
In acceptance tests, it’s desirable to run those background jobs immediately, skipping the queueing component, to avoid writing custom code to work the jobs off.
Configure RSpec request specs with a custom run_background_jobs_immediately method:
RSpec.configure do |config|
# if you're using Capybara 1.x, :feature should be replaced with :request
config.around(:each, type: :feature) do |example|
run_background_jobs_immediately do
example.run
end
end
config.include BackgroundJobs
end
A Delayed::Job implementation of the method:
# spec/support/background_jobs.rb
module BackgroundJobs
def run_background_jobs_immediately
delay_jobs = Delayed::Worker.delay_jobs
Delayed::Worker.delay_jobs = false
yield
Delayed::Worker.delay_jobs = delay_jobs
end
end
A Resque implementation of the method:
# spec/support/background_jobs.rb
module BackgroundJobs
def run_background_jobs_immediately
inline = Resque.inline
Resque.inline = true
yield
Resque.inline = inline
end
end
Voilà.
