I have been following a tutorial from a (semi-outdated) textbook
describing how to create a rails social networking app. I have reached
the testing phase and have encountered an error I can’t seem to solve.
It originates from an asset call in the site_controller_test.rb file.
Error message:
- Failure:
test_registration_success [test/functional/
site_controller_test.rb:49]:
expected to not be nil.
4 tests, 9 assertions, 1 failures, 0 errors
site_controller_test.rb:
require File.dirname(FILE) + ‘/…/test_helper’
require ‘site_controller’
Re-raise errors caught by the controller.
class SiteController; def rescue_action(e) raise e end; end
class SiteControllerTest < ActionController::TestCase
def setup
@controller = SiteController.new
@request = ActionController::TestRequest.new
@response = ActionController::TestResponse.new
end
Replace this with your real tests.
def test_truth
assert true
end
def test_index
get :index
title = assigns(:title)
assert_equal “The Water Cooler Site”, title
assert_response :success
assert_template “index”
end
Make sure the registration page responds with the proper form.
def test_registration_page
get :register
title = assigns(:title)
assert_equal “Registration Page”, title
assert_response :success
assert_template “register”
end
Test a valid registration.
def test_registration_success
post :register, :user=>{ :user_name => “rayjay6295”,
:email => “[email protected]”,
:password => “password”}
# Test assignment of user.
user = assigns(:user)
assert_not_nil user
# Test new user in database.
new_user = User.find_by_user_name_and_password(user.user_name,
user.password)
assert_not_nil new_user
assert_equal new_user, user
# Test flash and redirect.
assert_equal "User #{new_user.user_name} created!", flash[:notice]
assert_redirected_to :action => "index"
end

Thanks for any help. It seems like it can retrieve a user from the
post method fine, but once it tries to either insert or pull from the
database it runs into trouble.
