Using @current_user in tests

Rails
1

I am still trying to run this test
setup do

@comment = comments(:hello)
@comment.commenter = "cleb"
@comment.body = "hello"
@comment.user_id = 1
@cuser = User.find_by_id(session[:user_id])

end
test “should create comment” do

assert_difference('Comment.count') do
  post :create, :comment => @comment.attributes, :user_id => 2
end

assert_redirected_to comment_path(assigns(:comment))

end

I get this error

test_should_create_comment(CommentsControllerTest):
NoMethodError: undefined method `login’ for nil:NilClass

This is from comments.controller

def create
@cuser = @current_user
@user = User.find(params[:user_id])
@user.comments.create(:user_id => @user.id, :commenter =>
@cuser.login, :body => params[:comment][:body])
respond_to do |format|
format.js
format.html {redirect_to user_path}
end
end

How do I give the controller the required @current_user ?

(Derived from @current_user = User.find_by_id(session[:user_id])

What am I doing wrong?

The first thing is that you have not noticed that the error is
pointing out a bug in your code (as tests should do). You should be
checking in create that there is a user logged in (or not allowing
access to the action if no-one is logged in). So first you need to
add a test to check that the action cannot be accessed if no-one is
logged in. In order to get the test you have shown to pass you need
to effectively login a user by setting up the session. I have to go
so have not time to describe it but if you google for setting session
in rails tests then you should easily find it.
