使用RSpec和Action Mailer进行测试：清除排队的电子邮件？

Question

The Active Job Test Helper provides the helpful method, clear_enqueued_jobs.

Is there an equivalent for Action Mailer to clear enqueued emails?

Answer 1

Yes you can configure rspec to clear the mailers before each test like:

RSpec.configure do |config|
  config.before(:each) do
    ActionMailer::Base.deliveries.clear
  end
end

In case of enqueue mails, Active Job Test Helper is included in ActiveMailer::TestHelper so you should be able to use the clear_enqueued_jobs method too.
