assert_enqueued_jobs(number, only: nil, except: nil, queue: nil, &block)
Asserts that the number of enqueued jobs matches the given number.
def test_jobs
assert_enqueued_jobs 0
HelloJob.perform_later('david')
assert_enqueued_jobs 1
HelloJob.perform_later('abdelkader')
assert_enqueued_jobs 2
end
If a block is passed, asserts that the block will cause the specified number of jobs to be enqueued.
def test_jobs_again
assert_enqueued_jobs 1 do
HelloJob.perform_later('cristian')
end
assert_enqueued_jobs 2 do
HelloJob.perform_later('aaron')
HelloJob.perform_later('rafael')
end
end
Asserts the number of times a specific job was enqueued by passing :only
option.
def test_logging_job
assert_enqueued_jobs 1, only: LoggingJob do
LoggingJob.perform_later
HelloJob.perform_later('jeremy')
end
end
Asserts the number of times a job except specific class was enqueued by passing :except
option.
def test_logging_job
assert_enqueued_jobs 1, except: HelloJob do
LoggingJob.perform_later
HelloJob.perform_later('jeremy')
end
end
:only
and :except
options accept Class
, Array
of Class
, or Proc. When passed a Proc, a hash containing the job’s class and it’s argument are passed as argument.
Asserts the number of times a job is enqueued to a specific queue by passing :queue
option.
def test_logging_job
assert_enqueued_jobs 2, queue: 'default' do

assert_enqueued_with(job: nil, args: nil, at: nil, queue: nil, priority: nil, &block)
Asserts that the job has been enqueued with the given arguments.
def test_assert_enqueued_with
MyJob.perform_later(1,2,3)
assert_enqueued_with(job: MyJob, args: [1,2,3])
MyJob.set(wait_until: Date.tomorrow.noon, queue: "my_queue").perform_later
assert_enqueued_with(at: Date.tomorrow.noon, queue: "my_queue")
end
For keyword arguments, specify them as a hash inside an array:
def test_assert_enqueued_with_keyword_arguments
MyJob.perform_later(arg1: 'value1', arg2: 'value2')
assert_enqueued_with(job: MyJob, args: [{ arg1: 'value1', arg2: 'value2' }])
end
The given arguments may also be specified as matcher procs that return a boolean value indicating whether a job’s attribute meets certain criteria.
For example, a proc can be used to match a range of times:
def test_assert_enqueued_with
at_matcher = ->(job_at) { (Date.yesterday..Date.tomorrow).cover?(job_at) }
MyJob.set(wait_until: Date.today.noon).perform_later
assert_enqueued_with(job: MyJob, at: at_matcher)
end
A proc can also be used to match a subset of a job’s args:
def test_assert_enqueued_with
args_matcher = ->(job_args) { job_args[0].key?(:foo) }
MyJob.perform_later(foo: "bar", other_arg: "No need to check in the test")
assert_enqueued_with(job: MyJob, args: args_matcher)
end
If a block is passed, asserts that the block will cause the job to be enqueued with the given arguments.
def test_assert_enqueued_with
assert_enqueued_with(job: MyJob, args: [1,2,3]) do
MyJob.perform_later(1,2,3)
end
assert_enqueued_with(job: MyJob, at: Date.tomorrow.noon) do
MyJob.set(wait_until: Date.tomorrow.noon).perform_later
end

If the :at
option is specified, then only jobs that have been enqueued to run at or before the given time will be performed. This includes jobs that have been enqueued without a time.
If queue_adapter_for_test
is overridden to return a different adapter, perform_enqueued_jobs
will merely execute the block.
