.sidekiq_perform_inline(klass, args, item = nil) ⇒ Object

Like a Sidekiq worker’s perform_inline, but allows an arbitrary item to be used, rather than just the given class and args. For example, when testing, you may need to assume something like ‘retry_count’ is in the job payload, but that can’t be included with perform_inline. This allows those arbitrary job payload fields to be included when the job is run.

#publish(eventname = nil, expected_payload = nil) ⇒ Object

RSpec matcher – set up an expectation that an event will be fired with the specified eventname and optional expected_payload.

expect {
    Myapp::Customer.create( attributes )
}.to publish( 'myapp.customer.create' )

expect {
    Myapp::Customer.create( attributes )
}.to publish( 'myapp.customer.create', [1] )

expect { enter_hatch() }.
    to publish( 'myapp.hatch.entered' ).
    with_payload( [4, 8, 15, 16, 23, 42] )

expect { cook_potatoes() }.
    to publish( 'myapp.potatoes.cook' ).
    with_payload( including( a_hash_containing( taste: 'good' ) ) )
