end

def test_email_with_named_arguments

end

def test_email_with_parameters_and_arguments
  ContactMailer.with(greeting: "Hello").welcome("Cheers", "Goodbye").deliver_later
  assert_enqueued_email_with ContactMailer, :welcome, params: { greeting: "Hello" }, args: ["Cheers", "Goodbye"]
end

def test_email_with_parameters_and_named_arguments
  ContactMailer.with(greeting: "Hello").welcome(farewell: "Goodbye").deliver_later
  assert_enqueued_email_with ContactMailer, :welcome, params: { greeting: "Hello" }, args: [{farewell: "Goodbye"}]
end

def test_email_with_parameterized_mailer
  ContactMailer.with(greeting: "Hello").welcome.deliver_later
  assert_enqueued_email_with ContactMailer.with(greeting: "Hello"), :welcome
end

def test_email_with_matchers
  ContactMailer.with(greeting: "Hello").welcome("Cheers", "Goodbye").deliver_later
  assert_enqueued_email_with ContactMailer, :welcome,
    params: ->(params) { /hello/i.match?(params[:greeting]) },
    args: ->(args) { /cheers/i.match?(args[0]) }
end

If a block is passed, that block should cause the specified email to be enqueued.

def test_email_in_block
  assert_enqueued_email_with ContactMailer, :welcome do
    ContactMailer.welcome.deliver_later
  end
end

If args is provided as a Hash, a parameterized email is matched.

def test_parameterized_email
  assert_enqueued_email_with ContactMailer, :welcome,
    args: {email: 'user@example.com'} do
    ContactMailer.with(email: 'user@example.com').welcome.deliver_later
  end
end

        ActionMailer.deprecator.warn <<~MSG
          Passing a Hash to the assert_enqueued_email_with :args kwarg causes the
          Hash to be treated as params. This behavior is deprecated and will be
          removed in Rails 7.2.

          To specify a params Hash, use the :params kwarg:

            assert_enqueued_email_with MyMailer, :my_method, params: { my_param: "value" }

          Or, to specify named mailer args as a Hash, wrap the Hash in an array:

            assert_enqueued_email_with MyMailer, :my_method, args: [{ my_arg: "value" }]
            # OR
            assert_enqueued_email_with MyMailer, :my_method, args: [my_arg: "value"]
        MSG

        params, args = args, nil
      end

      args = Array(args) unless args.is_a?(Proc)
      queue ||= mailer.deliver_later_queue_name || ActiveJob::Base.default_queue_name

      expected = ->(job_args) do
        job_kwargs = job_args.extract_options!

        [mailer.to_s, method.to_s, "deliver_now"] == job_args &&
          params === job_kwargs[:params] && args === job_kwargs[:args]
      end

      assert_enqueued_with(job: mailer.delivery_job, args: expected, queue: queue.to_s, &block)
    end
