What's this?

assert_enqueued_with(job: nil, args: nil, at: nil, queue: nil, priority: nil, &block) public

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
end
