Parent: | Test::Rails::FunctionalTestCase |
ControllerTestCase allows controllers to be tested independent of their views.
The test class must be named after your controller class name, so if you‘re testing actions for the RouteController you would name your test case RouteControllerTest.
The test names should be in the form of test_action_edgecase where ‘action’ corresponds to the name of the controller action, and ‘edgecase’ describes the scenario you are testing.
If you are testing an action named ‘show’ your test should be named test_show. If your action behaves differently depending upon its arguments then you can make the test name descriptive like test_show_photos and test_show_no_photos.
class RouteControllerTest < Test::Rails::ControllerTestCase fixtures :users, :routes, :points, :photos def test_delete # Store current count count = Route.count # Set up our environment session[:username] = users(:herbert).username # perform the delete action get :delete, :id => routes(:work).id # Assert we got a 200 assert_response :success # Assert controller deleted route assert_equal count-1, Route.count # Ensure that @action_title is set properly assert_assigned :action_title, "Deleting \"#{routes(:work).name}\"" # Ensure that @route is set properly assert_assigned :route, routes(:work) end end
class ApplicationController < ActionController::Base ## # Send an email when we get an unhandled exception. def log_error(exception) case exception when ::ActionController::RoutingError, ::ActionController::UnknownAction, ::ActiveRecord::RecordNotFound then # ignore else unless RAILS_ENV == 'development' then Email.deliver_error exception, params, session, @request.env end end end end ## # Dummy Controller just for testing. class DummyController < ApplicationController def error # Simulate a bug in our application raise RuntimeError end end class DummyControllerTest < Test::Rails::ControllerTestCase def test_error_email # The rescue_action added by ControllerTestCase needs to be removed so # that exceptions fall through to the real error handler @controller.class.send :remove_method, :rescue_action # Fire off a request get :error # We should get a 500 assert_response 500 # And one delivered email assert_equal 1, @deliveries.length, 'error email sent' end end

Asserts that the assigns variable ivar is assigned to value. If value is omitted, asserts that assigns variable ivar exists.
Asserts that key of flash has content. If content is a Regexp, then the assertion will fail if the Regexp does not match.
controller:
flash[:notice] = 'Please log in'
test:
assert_flash :notice, 'Please log in'
Checks your assert_assigned tests against the instance variables in assigns. Fails if the two don‘t match.
Add util_audit_assert_assigned to your teardown. If you have instance variables that you don‘t need to set (for example, were set in a before_filter in ApplicationController) then add them to the @assigns_ignored instance variable in your setup.
class UserController < ApplicationController def new # ... @login_form = false end end
class UserControllerTest < Test::Rails::ControllerTestCase def teardown super util_audit_assert_assigned end def test_new get :new assert_response :success # no assert_assigns for @login_form end end
