测试轨道功能时的错误

您好，我在测试应用程序的功能部分时遇到以下错误，基本上测试运行，但我收到这些错误，我不知道它指的是什么。

手推车控制器测试 需要'test_helper'

class CartsControllerTest < ActionController::TestCase
setup do
@cart = carts(:one)
end

test "should get index" do
get :index
assert_response :success
assert_not_nil assigns(:carts)
end

test "should get new" do
get :new
assert_response :success
end

test "should create cart" do
assert_difference('Cart.count') do
post :create, cart: @cart.attributes
end

assert_redirected_to cart_path(assigns(:cart))
end

test "should show cart" do
get :show, id: @cart
assert_response :success
end

test "should get edit" do
get :edit, id: @cart
assert_response :success
end

什么可能导致这种情况发生？

Answer 1

看起来它在加载固定装置时遇到了问题。它无法弄清楚如何解决您的setup 定义中的carts 方法。

您是否在test/fixtures/ 目录中设置了它们？

请参阅rails testing guide 了解如何正确设置它们，但我猜你想要这样的东西：

test/fixtures/carts.yml:

one:
  name: bork
  foo_attribute: bar_value
two:
  name: other_cart
  foo_attribute: blah_value

Answer 2

检查是否已创建测试数据库。
