This is not actually removed in Sidekiq 5, just disabled by default. See: https://github.com/mperham/sidekiq/blob/master/5.0-Upgrade.md

You just need to put something like

Sidekiq::Extensions.enable_delay! if Sidekiq::VERSION > 4

in your test setup.

@packrat386

The BeDelayed matcher can still work in Sidekiq 5+ if enabled: https://github.com/mperham/sidekiq/blob/master/5.0-Upgrade.md#whats-new

I enable in order to test here: https://github.com/philostler/rspec-sidekiq/pull/126/files#diff-93830fa29d616f7c87903d08b5b1b29aR25
