Provides helper methods for testing Active Job
- A
- P
- Q
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, that 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
The number of times a specific job is enqueued can be asserted.
def test_logging_job
assert_enqueued_jobs 1, only: LoggingJob do
LoggingJob.perform_later
HelloJob.perform_later('jeremy')
end
end
The number of times a job is enqueued to a specific queue can also be asserted.
def test_logging_job
assert_enqueued_jobs 2, queue: 'default' do
LoggingJob.perform_later
HelloJob.perform_later('elfassy')
end
end
# File activejob/lib/active_job/test_helper.rb, line 107 def assert_enqueued_jobs(number, only: nil, queue: nil) if block_given? original_count = enqueued_jobs_size(only: only, queue: queue) yield new_count = enqueued_jobs_size(only: only, queue: queue) assert_equal number, new_count - original_count, "#{number} jobs expected, but #{new_count - original_count} were enqueued" else actual_count = enqueued_jobs_size(only: only, queue: queue) assert_equal number, actual_count, "#{number} jobs expected, but #{actual_count} were enqueued" end end
Asserts that the job passed in the block has been 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
# File activejob/lib/active_job/test_helper.rb, line 262 def assert_enqueued_with(job: nil, args: nil, at: nil, queue: nil) original_enqueued_jobs_count = enqueued_jobs.count expected = { job: job, args: args, at: at, queue: queue }.compact serialized_args = serialize_args_for_assertion(expected) yield in_block_jobs = enqueued_jobs.drop(original_enqueued_jobs_count) matching_job = in_block_jobs.find do |in_block_job| serialized_args.all? { |key, value| value == in_block_job[key] } end assert matching_job, "No enqueued job found with #{expected}" instantiate_job(matching_job) 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, that block should 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
It can be asserted that no jobs of a specific kind are enqueued:
def test_no_logging
assert_no_enqueued_jobs only: LoggingJob do
HelloJob.perform_later('jeremy')
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, that block should 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
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
the job call.
def test_jobs
assert_performed_jobs 0
perform_enqueued_jobs do
HelloJob.perform_later('xavier')
end
assert_performed_jobs 1
perform_enqueued_jobs do
HelloJob.perform_later('yves')
assert_performed_jobs 2
end
end
If a block is passed, that block should 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
The block form 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
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

Asserts that the job passed in the block has been performed with the given arguments.
def test_assert_performed_with
assert_performed_with(job: MyJob, args: [1,2,3], queue: 'high') do
MyJob.perform_later(1,2,3)

Performs all enqueued jobs in the duration of the block.
def test_perform_enqueued_jobs
perform_enqueued_jobs do
MyJob.perform_later(1, 2, 3)
end
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

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