Testing Resque background jobs with RSpec

Let’s say you have a model which involves a background job upon save, or you want to schedule a background job in the controller, how to do you make sure the background will run correctly? One way is to use expectation mock like Resque.should_receive(:enqueue).with(…), but a simpler/better way is just put the following in your before…end block:

Resque.inline = true

That will run your background job right away.
