Mosquito::TestBackend

An in-memory noop backend desigend to be used in application testing.

The test mode backend simply makes a copy of job_runs at enqueue time and holds them in a class getter array.

Job run id, config (aka parameters), and runtime class are kept in memory, and a truncate utility function is provided.

Activate test mode configure the test backend like this:

Mosquito.configure do |settings|
  settings.backend = Mosquito::TestBackend
end

Then in your tests:

describe "testing" do
  it "enqueues the job" do
    # build and enqueue a job
    job_run = EchoJob.new(text: "hello world").enqueue

    # assert that the job was enqueued
    lastest_enqueued_job = Mosquito::TestBackend.enqueued_jobs.last

    # check the job config
    assert_equal "hello world", latest_enqueued_job.config["text"]

    # check the job_id matches
    assert_equal job_run.id, latest_enqueued_job.id

    # optionally, truncate the history
    Mosquito::TestBackend.flush_enqueued_jobs!
  end
end
