Rails Clearance, Unit Test Controller - ruby-on-rails

Question

I'm having trouble getting the Clearance authentication to work with Rails controller unit testing. I've followed the instructions at https://github.com/thoughtbot/clearance "Controller Test Helpers". How do you unit test controllers that require authentication?
I get the following error:
GoalsControllerTest#test_should_get_index:
NoMethodError: undefined method `sign_in_as' for #<GoalsControllerTest:0x007f8c41c6b9c8>
test/controllers/goals_controller_test.rb:7:in `block in <class:GoalsControllerTest>'
test/test_helper.rb
require 'clearance/test_unit'
test/controller/goals_controller_test.rb
require 'test_helper'
class GoalsControllerTest < ActionDispatch::IntegrationTest
setup do
user = User.new(fname: "Test", lname: "User", email: "testuser#test.com", password: "password")
sign_in_as(user)
#goal = goals(:one)
end

Answer 1

i've same problem with you, but now fixed by this answer https://github.com/thoughtbot/clearance/issues/695
Enable the Middleware in Test:
# config/environments/test.rb
MyRailsApp::Application.configure do
# ...
config.middleware.use Clearance::BackDoor
# ...
end
In my test/test_helper.rb file, I wrote this following code.
class ActionDispatch::IntegrationTest
def manual_sign_in_as(user)
post session_url, params: {
session: {
email: user.email,
password: user.password
}
}
end
end
Rails 5 subclasses controller tests from ActionDispatch::IntegrationTest by default, so I only had to follow the instructions on the readme from here https://github.com/thoughtbot/clearance.
class PostsControllerTest < ActionDispatch::IntegrationTest
test "user visits index page while logged in"
user = User.create!(email: "example#example.com", password: "letmein")
get links_url(as: user)
# and
post links_url(as: user), params: { post: { title: "hi" } }
end
end

Are you using Rails 5? Rails 5 unified integration and controller tests behind ActionDispatch::IntegrationTest. When you require clearance/test_unit, Clearance is only adding it's helpers to ActionController::TestCase.
I think you could do:
class ActionDispatch::IntegrationTest
include Clearance::Testing::ControllerHelpers
end
in your test_helper.rb file in order to get access to the helpers in those tests. However, I'm not certain the helpers themselves will work in that context.
If you could give that a try, it'd be helpful. This should be fixed in Clearance as well. Since I don't use TestUnit/MiniTest myself I sometimes miss things like this.
