How to check what is queued in ActiveJob using Rspec

The accepted answer no longer works for me, so I tried Michael H.’s suggestion in the comments, which works.

describe 'whatever' do
  include ActiveJob::TestHelper

  after do
    clear_enqueued_jobs
  end  

  it 'should email' do
    expect(enqueued_jobs.size).to eq(1)
  end
end
