I have a simple worker that is accessing the size of its own queue:
require 'sidekiq/api'
class TestWorker
include Sidekiq::Worker
def perform(*args)
Sidekiq::Queue.new('test').size
end
end
I am then testing this worker:
require 'rails_helper'
RSpec.describe TestWorker, type: :worker do
describe '#perform' do
it 'executes the job without connecting to Redis in the testing environment' do
require 'sidekiq/testing'
Sidekiq::Testing.fake! do
TestWorker.perform_async
TestWorker.drain
end
end
end
end
This test is failing because it tries to access redis:
1) TestWorker#perform executes the job without connecting to Redis in the testing environment
Failure/Error: Sidekiq::Queue.new('test').size
Redis::CannotConnectError:
Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)

According to Sidekiq documentation related to Sidekiq::Testing.fake! "instead of pushing jobs to Redis, Sidekiq pushes them into a jobs array which you can access"
Why is Sidekiq::Queue.new('test').size trying to connect to Redis instead of checking the size of the job array in the test environment?
Is there a way to make Sidekiq::Queue work with Sidekiq::Testing.fake! or should I mock it?
Sidekiq's API does not have a testing mode, [it] will always hit Redis.
