Module: ActiveJob::TestHelper

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

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

Asserts that no jobs have been enqueued.

def test_jobs
  assert_no_enqueued_jobs
  HelloJob.perform_later('jeremy')
  assert_enqueued_jobs 1
end

If a block is passed, asserts that the block will not cause any job to be enqueued.

def test_jobs_again
  assert_no_enqueued_jobs do
    # No job should be enqueued from this block
  end
end

Asserts that no jobs of a specific kind are enqueued by passing :only option.

def test_no_logging
  assert_no_enqueued_jobs only: LoggingJob do
    HelloJob.perform_later('jeremy')
  end
end

Asserts that no jobs except specific class are enqueued by passing :except option.

def test_no_logging
  assert_no_enqueued_jobs except: HelloJob do
    HelloJob.perform_later('jeremy')
  end
end

:only and :except options accepts ::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 that no jobs are enqueued to a specific queue by passing :queue option

def test_no_logging
  assert_no_enqueued_jobs queue: 'default' do
    LoggingJob.set(queue: :some_queue).perform_later
  end
end

Note: This assertion is simply a shortcut for:

assert_enqueued_jobs 0, &block

Asserts that no jobs have been performed.

def test_jobs
  assert_no_performed_jobs

  perform_enqueued_jobs do
    HelloJob.perform_later('matthew')
    assert_performed_jobs 1
  end
end

If a block is passed, asserts that the block will not cause any job to be performed.

def test_jobs_again
  assert_no_performed_jobs do
    # No job should be performed from this block
  end
end

The block form supports filtering. If the :only option is specified, then only the listed job(s) will not be performed.

def test_no_logging
  assert_no_performed_jobs only: LoggingJob do
    HelloJob.perform_later('jeremy')
  end
end

Also if the :except option is specified, then the job(s) except specific class will not be performed.

def test_no_logging
  assert_no_performed_jobs except: HelloJob do
    HelloJob.perform_later('jeremy')
  end
end

:only and :except options accepts ::Class, ::Array of ::Class or Proc. When passed a Proc, an instance of the job will be passed as argument.

If the :queue option is specified, then only the job(s) enqueued to a specific queue will not be performed.

def test_assert_no_performed_jobs_with_queue_option
  assert_no_performed_jobs queue: :some_queue do
    HelloJob.set(queue: :other_queue).perform_later("jeremy")
  end
end

Note: This assertion is simply a shortcut for:

assert_performed_jobs 0, &block

Asserts that the number of performed jobs matches the given number. If no block is passed, #perform_enqueued_jobs must be called around or after the job call.

def test_jobs
  assert_performed_jobs 0

  perform_enqueued_jobs do
    HelloJob.perform_later('xavier')
  end
  assert_performed_jobs 1

  HelloJob.perform_later('yves')

  perform_enqueued_jobs

  assert_performed_jobs 2
end

If a block is passed, asserts that the block will cause the specified number of jobs to be performed.

def test_jobs_again
  assert_performed_jobs 1 do
    HelloJob.perform_later('robin')
  end

  assert_performed_jobs 2 do
    HelloJob.perform_later('carlos')
    HelloJob.perform_later('sean')
  end
end

This method also supports filtering. If the :only option is specified, then only the listed job(s) will be performed.

def test_hello_job
  assert_performed_jobs 1, only: HelloJob do
    HelloJob.perform_later('jeremy')
    LoggingJob.perform_later
  end
end

Also if the :except option is specified, then the job(s) except specific class will be performed.

def test_hello_job
  assert_performed_jobs 1, except: LoggingJob do
    HelloJob.perform_later('jeremy')
    LoggingJob.perform_later
  end
end

An array may also be specified, to support testing multiple jobs.

def test_hello_and_logging_jobs
  assert_nothing_raised do
    assert_performed_jobs 2, only: [HelloJob, LoggingJob] do
      HelloJob.perform_later('jeremy')
      LoggingJob.perform_later('stewie')
      RescueJob.perform_later('david')
    end
  end
end

A proc may also be specified. When passed a Proc, the job’s instance will be passed as argument.

def test_hello_and_logging_jobs
  assert_nothing_raised do
    assert_performed_jobs(1, only: ->(job) { job.is_a?(HelloJob) }) do
      HelloJob.perform_later('jeremy')
      LoggingJob.perform_later('stewie')
      RescueJob.perform_later('david')
    end
  end
end

If the :queue option is specified, then only the job(s) enqueued to a specific queue will be performed.

def test_assert_performed_jobs_with_queue_option
  assert_performed_jobs 1, queue: :some_queue do
    HelloJob.set(queue: :some_queue).perform_later("jeremy")
    HelloJob.set(queue: :other_queue).perform_later("bogdan")
  end
end

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

Performs all enqueued jobs. If a block is given, performs all of the jobs that were enqueued throughout the duration of the block. If a block is not given, performs all of the enqueued jobs up to this point in the test.

def test_perform_enqueued_jobs
  perform_enqueued_jobs do
    MyJob.perform_later(1, 2, 3)
  end
  assert_performed_jobs 1
end

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

  perform_enqueued_jobs

  assert_performed_jobs 1
end

This method also supports filtering. If the :only option is specified, then only the listed job(s) will be performed.

def test_perform_enqueued_jobs_with_only
  perform_enqueued_jobs(only: MyJob) do
    MyJob.perform_later(1, 2, 3) # will be performed
    HelloJob.perform_later(1, 2, 3) # will not be performed
  end
  assert_performed_jobs 1
end

Also if the :except option is specified, then the job(s) except specific class will be performed.

def test_perform_enqueued_jobs_with_except
  perform_enqueued_jobs(except: HelloJob) do
    MyJob.perform_later(1, 2, 3) # will be performed
    HelloJob.perform_later(1, 2, 3) # will not be performed
  end
  assert_performed_jobs 1
end

:only and :except options accepts ::Class, ::Array of ::Class or Proc. When passed a Proc, an instance of the job will be passed as argument.

If the :queue option is specified, then only the job(s) enqueued to a specific queue will be performed.

def test_perform_enqueued_jobs_with_queue
  perform_enqueued_jobs queue: :some_queue do
    MyJob.set(queue: :some_queue).perform_later(1, 2, 3) # will be performed
    HelloJob.set(queue: :other_queue).perform_later(1, 2, 3) # will not be performed
  end
  assert_performed_jobs 1
end

If the :at option is specified, then only run jobs enqueued to run immediately or before the given time

Accesses the queue_adapter set by Base.

def test_assert_job_has_custom_queue_adapter_set
  assert_instance_of CustomQueueAdapter, HelloJob.queue_adapter
end

Specifies the queue adapter to use with all Active Job test helpers.

Returns an instance of the queue adapter and defaults to QueueAdapters::TestAdapter.

Note: The adapter provided by this method must provide some additional methods from those expected of a standard QueueAdapter in order to be used with the active job test helpers. Refer to QueueAdapters::TestAdapter.
