Method: ActiveJob::TestHelper#assert_performed_with

Defined in:

activejob/lib/active_job/test_helper.rb

#assert_performed_with(job: nil, args: nil, at: nil, queue: nil, priority: nil, &block) ⇒ Object

Asserts that the job has been performed with the given arguments.

def test_assert_performed_with
  MyJob.perform_later(1,2,3)

  perform_enqueued_jobs

  assert_performed_with(job: MyJob, args: [1,2,3])

  MyJob.set(wait_until: Date.tomorrow.noon, queue: "my_queue").perform_later

  perform_enqueued_jobs

  assert_performed_with(at: Date.tomorrow.noon, queue: "my_queue")
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_performed_with
  at_matcher = ->(job_at) { (Date.yesterday..Date.tomorrow).cover?(job_at) }

  MyJob.set(wait_until: Date.today.noon).perform_later

  perform_enqueued_jobs

  assert_performed_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_performed_with
  args_matcher = ->(job_args) { job_args[0].key?(:foo) }

  MyJob.perform_later(foo: "bar", other_arg: "No need to check in the test")

  perform_enqueued_jobs

  assert_performed_with(job: MyJob, args: args_matcher)
end

If a block is passed, that block performs all of the jobs that were enqueued throughout the duration of the block and asserts that the job has been performed with the given arguments in the block.

def test_assert_performed_with
  assert_performed_with(job: MyJob, args: [1,2,3]) do
    MyJob.perform_later(1,2,3)
  end

  assert_performed_with(job: MyJob, at: Date.tomorrow.noon) do
    MyJob.set(wait_until: Date.tomorrow.noon).perform_later
  end
end
