Test:integration Expected response to be a <:redirect>, but was <404>

Hello,

I’m trying to write some tests and I get a failure error on one test,
which I am not sure why or where is my mistake.

In my test/integration/product_test.rb I have:

require ‘test_helper’

class ProductTest < ActionController::IntegrationTest
fixtures :all

test “product_administartion_by_admin” do
category = Category.create(:name => ‘Parts’)

quentin = new_session_as(:quentin)
product = quentin.add_product :product => {
  :title => 'Clip',
  :category_id => category.id,
  :sku => 54321,
  :desctription => 'some text',
  :price => 8.71
}

end

private

module ProductTestDSL
attr_writer :name

def add_product(parameters)
  post "/product/create", parameters
  assert_response :redirect
  follow_redirect!
  assert_response :success
  assert_template "/product/show"
  return Product.find_by_title(parameters[:product][:title])
end

end

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

The error I get is:

  1. Failure:
    test_product_administartion_by_admin(ProductTest)
    [/test/integration/product_test.rb:26:in add_product' /test/integration/product_test.rb:10:intest_product_administartion_by_admin’]:
    Expected response to be a <:redirect>, but was <404>

1 tests, 1 assertions, 1 failures, 0 errors
rake aborted!

Looking around – someone had a problem that the new object was not
created or saved. One of the tests in products_controller_test.rb has
no problem creating a new product.

What am I missing?

TIA,
Elle
