4,147 PointsPraveen. I encountered the same problem because in the setup of the test, the example was using new to create @user_friendship. on line 30 of user_friendship_test.rb make sure it reads:
context "#send_request_email" do
setup do
@user_friendship = UserFriendship.create user: users(:jason), friend: users(:mike)
end
and not
setup do
@user_friendship = UserFriendship.new user: users(:jason), friend: users(:mike)
end

Treehouse Guest TeacherHey Praveen, can you post the user friendship test file here too?
Praveen Boddu
1,669 PointsHey Jason,
Below is my test file. Rest of the tests passes. I wrote tests for accepting friendship as well and they pass without any issue.
require 'test_helper'
class UserFriendshipTest < ActiveSupport::TestCase
should belong_to(:user) should belong_to(:friend)
test "creating a friendship works without raising an exception" do assert_nothing_raised do UserFriendship.create user: users(:rajesh), friend: users(:peter) end end
test "that creating a friendship based on user id and friend id works" do UserFriendship.create user_id: users(:rajesh).id, friend_id: users(:peter).id assert users(:rajesh).friends.include?(users(:peter)) end
context "a new instance" do setup do @user_friendship = UserFriendship.new user: users(:rajesh), friend: users(:peter) end
should "have a pending state" do
assert_equal 'pending', @user_friendship.state
end
end
context "#send_request_email" do setup do @user_friendship = UserFriendship.new user: users(:rajesh), friend: users(:peter) end
should "send an email" do
assert_difference 'ActionMailer::Base.deliveries.size', 1 do
@user_friendship.send_request_email
end
end
end
context "#accept!" do setup do @user_friendship = UserFriendship.new user: users(:rajesh), friend: users(:peter) end
should "set the state to accepted" do
@user_friendship.accept!
assert_equal "accepted", @user_friendship.state
end
should "send an acceptance email" do
assert_difference 'ActionMailer::Base.deliveries.size', 1 do
@user_friendship.accept!
end
end
should "inculde the friend in the list of friends" do
@user_friendship.accept!
users(:rajesh).friends.reload
assert users(:rajesh).friends.include?(users(:peter))
end
end end

1,669 PointsAh..That makes total sense. Thanks Mike. What I don't understand is how the test got passed in the video?
