Unable to run ActionMailer assertions within tests?










0















I can't figure out why I am unable to use the ActionMailer assertions within my tests. I generated a Rails 5.2.1 application from scratch, scaffolded a model, and still get a NoMethodError when I call methods like assert_emails.



require 'test_helper'

class UserTest < ActiveSupport::TestCase
test "the truth" do
assert_emails 0 do
assert true
end
end
end


This raises an exception:



NoMethodError: undefined method `assert_emails' for #<UserTest:0x007ff3ebeb58c0>


What am I missing?
