Assert_redirected_to not working as expected

Rails
1

I’ve installed the “acts_as_authenticated” plugin and made some
modifications to the controller (app/controllers/account_controller.rb)
“signup” module as follows:

===
def signup
@page_title = ‘Create Account’
@user = User.new(@params[:user])
if request.post?
if @user.save
session[:user] = User.authenticate(@user.login, @user.password)
redirect_to(:controller => ‘/home’, :action => ‘welcome’)
else
flash[:notice] = “Signup unsuccessful!”
end
end
end

The “success” integration test
(test/integration/authentication_test.rb) looks like this (snipped):

===
class AuthenticationTest < ActionController::IntegrationTest
def setup
User.create(:login => “goober”,
:email => “[email protected]”,
:password => “gomer”,
:password_confirmation => “gomer”)
end

…

def test_successful_signup
gooddog = enter_site(:gooddog)
gooddog.signs_up_successfully
end

…

private

module BrowsingTestDSL
include ERB::Util
attr_writer :name

…

def signs_up_successfully
  post_signup("gooddog", "[email protected]", "gooddog",

“gooddog”)
assert_redirected_to :controller => “home”, :action => “welcome”
end
…

private

def post_signup(login, email, password, confirm_password)
  post "/account/signup", :login => login, :email => email,

:password => password, :confirm_password => confirm_password
end

end

def enter_site(name)
open_session do |session|
session.extend(BrowsingTestDSL)
session.name = name
yield session if block_given?
end
end
end

===

I’m on Windows and am running the test using this command:

ruby test/integration/authentication_test.rb - n test_successful_signup

Resulting in:

“Expected response to be a <:redirect>, but was <200>”

Running live produces the desired behavior, i.e., a new user is
created, data stored in the database, and the user is redirected to a
Welcome page.

Is there something(s) about the test environment that I’ve missed?

Thanks,
Stan
