Topic: Unit testing - depot app of AGWDWR 4th ed
Having some issues with getting the unit tests to work. I started working on some of the bonus questions. For those that aren't familiar, the depot app is a simple store. It has products. Line items which belong to a cart and a product. A cart belongs to an order. As part of the bonus questions, I set up another model called PaymentType, which an order belongs to. My code on the site itself works just fine, it's the tests that are failing.
Here's my code:
class Order < ActiveRecord::Base
has_many :line_items, :dependent => :destroy
# PAYMENT_TYPES = ["Check", "Credit card", "Purchase order"]
belongs_to :payment_type
validates :name, :address, :email, :presence => true
validates_inclusion_of :payment_type_id, :in => PaymentType.all.map { |type| type.id }, :message => "- Invalid payment type selected"
def add_line_items_from_cart(cart)
cart.line_items.each do |item|
item.cart_id = nil
line_items << item
end
end
endorder_test.rb
require 'test_helper'
class OrderTest < ActiveSupport::TestCase
fixtures :orders
fixtures :payment_types
setup do
@order = orders(:one)
end
test "order attributes must not be empty" do
order = Order.new
assert order.invalid?
[:name, :address, :email, :payment_type].each do |sym|
assert order.errors[sym].any?
end
# test fixture values
assert @order.valid?
assert_not_equal @order.payment_type.id, nil
assert_not_equal @order.name, ''
assert_not_equal @order.address, ''
assert_not_equal @order.email, ''
end
endorders.yml (fixture) && payment_types.yml
one:
name: Dave Thomas
address: MyText
email: dave@example.org
payment_type: check
two:
name: MyString
address: MyText
email: MyString
payment_type: check
check:
name: Pay Check
# column: value
#
creditcard:
name: Credit CardWhen i run rake test:units, i receive the following failure:
1) Failure:
test_order_attributes_must_not_be_empty(OrderTest) [test/unit/order_test.rb:15]:
Failed assertion, no message given.
the line it refers to is: assert @order.valid?
Given the fixtures and test code. Do you have any ideas of what might be causing it to fail?
