Since `ActiveJob::TestHelper` globally sets
`ActiveJob::Base.queue_adapter` on setup, there is no benefit in
instantiating a new `TestAdapter` per tests. The original rationale was
to allow parallel tests to run without interference, but since they'd
all mutate the global `ActiveJob::Base.queue_adapter`, that was never
realized.
type.
This allows specific jobs to be tested, while preventing others from
being performed unnecessarily.
Example:
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.
Example:
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
Fixes#18802.
Trim space and document :only option.
1. The :test adapter wasn't going through a full cycle of
serialize/deserialize when performing jobs. Now it does
2. Regular AJ tests were not run for the :test adapter. Now they are
3. ActiveJob::TestHelper uses assert_valid_keys but doesn’t requires
the file that implements that method. Now it does
