The ActionMailer in my Rails 3.1 project has an odd behavior, the ActionMailer::Base.deliveries is empty in test while I can actually receive the email by running the code in rails console. Anybody can points out what wrong it is?

# spec/mailers/user_mailer_spec.rb
require "spec_helper"

describe UserMailer do
describe ".reminding_email" do
subject { UserMailer.reminding_email(user).deliver }
let(:user) { create :confirmed_user_with_mass_tasks }
it "should be delivered" do
ActionMailer::Base.deliveries.should_not be_empty
end
its(:to) { should == [user.email] }
its(:subject) { should == "Task Reminding" }
end
end

# app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
layout "email"
default from: Rails.env.production? ? "<production>@gmail.com" : "<test>@gmail.com"
def reminding_email(user)
@tasks = user.tasks.reminding_required
@current = Time.current
mail(to: user.email, subject: "Task Reminding")
end
end
Failures:

1) UserMailer.reminding_email should be delivered Failure/Error: ActionMailer::Base.deliveries.should_not be_empty expected empty? to return false, got true # ./spec/mailers/user_mailer_spec.rb:8:in `block (3 levels) in '

    end
    IIRC subject is evaluated lazily, so in this example
    UserMailer.reminding_email(user).deliver wouldn't be called at all

    Fred
    its(:to) { should == [user.email] }
    its(:subject) { should == "Task Reminding" }
    end
    end
