Clearing out ActionMailer::Base.deliveries after RSpec test
RSpec.describe UserMailer do before do # ActionMailer::Base.deliveries is a regular array ActionMailer::Base.deliveries = [] # or use ActionMailer::Base.deliveries.clear end it "sends welcome email" do user = create(:user) UserMailer.welcome_email(user).deliver_now expect(ActionMailer::Base.deliveries).to be_present endend
You can clear the deliveries after each test quite easily, adding this into your spec_helper.rb.
RSpec.configure do |config| config.before { ActionMailer::Base.deliveries.clear } endI'd suggest reading my article about the correct emails configuration in Rails where I talk also about testing them correctly.
As Andy Lindeman points out, clearing the deliveries is done automatically for mailer tests. However, for other types, simply add , :type => :mailer to the wrapping block to force the same behavior.
describe "tests that send emails", type: :mailer do # some testsend
