Functional testing with act as authenticated

Rails
1

I’m trying to run some functional tests for actions that are behind
authentication (via act as authenticated plugin), but am having
problems getting “current_user” set for the controller.

Here’s the test code:

def test_create
num_notes = Note.count

  post :create, :note => {:title => "Test Note", :msg => "Test

Message" }
assert_response :redirect
assert_redirected_to :action => ‘list’

  assert_equal num_notes + 1, Note.count

end

Here’s the contoller code that it is failing:

@note.user_id = current_user.id

I’ve added this include to the first line of the test class:

include AuthenticatedTestHelper

In the setup function I’ve added:

login_as :jeremy

There is a user in the fixure with the login of “jeremy”. So what am
I doing wrong?

I found that the default “authenticated_test_helper.rb” file was
throwing an error about the “users” method being undefined with the
following function:

def login_as(user)
@request.session[:user] = user ? users(user).id : nil
end

So I changed it to this:

def login_as(user)
@request.session[:user] = user ? User.find_by_login(user) : nil
end

This seemed to fix the problem. Is this an OK modification to make?
Why didn’t the code that it shipped with work?

And you are using the out-of-the-box fixtures system, with fixtures
:users
above every call to login_as?

sessions should only contain numbers (for various definitions of
“should”),
so you are missing an .id

Works for me. How sure are you that this assertion would pass before
your
login_as?

assert_not_nil users(:jeremy)

Then, I suspect something reconstitutes current_user at page hit time,
via
User.find_by_id(session[:user])

Storing entire objects in your session table is bad JuJu.
