assert_enqueued_with

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], queue: 'low')

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

The args argument also accepts a proc which will get passed the actual job’s arguments. Your proc needs to return a boolean value determining if the job’s arguments matches your expectation. This is useful to check only for a subset of arguments.

def test_assert_enqueued_with
  expected_args = ->(job_args) do
    assert job_args.first.key?(:foo)
  end

  MyJob.perform_later(foo: 'bar', other_arg: 'No need to check in the test')
  assert_enqueued_with(job: MyJob, args: expected_args, queue: 'low')
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], queue: 'low') 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
end
