我一直在实施carrierwave,它在浏览器中运行良好。但是,我的测试不断回复:
错误
1) Item
Failure/Error: it { should be_valid }
expected valid? to return true, got false
# ./spec/models/item_spec.rb:36:in `block (2 levels) in <top (required)>'
factories.rb
include ActionDispatch::TestProcess
FactoryGirl.define do
sequence(:email) { |n| "User#{n}@example.com"}
factory :user do
name "John doe"
email
password "foobar"
password_confirmation "foobar"
end
factory :list do
name "Lorem ipsum"
user
end
factory :item do
image { fixture_file_upload(Rails.root.join('spec', 'support', 'test_images', 'google.png'), 'image/png') }
title "Shirt"
link "www.example.com"
list
end
end
item_spec.rb
require 'spec_helper'
describe Item do
let(:user) { FactoryGirl.create(:user) }
let(:list) { FactoryGirl.create(:list) }
before do
@item = list.items.build(title: "Lorem ipsum")
@item.valid?
puts @item.errors.full_messages.join("\n")
end
subject { @item }
it { should respond_to(:title) }
it { should respond_to(:list_id) }
it { should respond_to(:list) }
it { should respond_to(:image) }
it { should respond_to(:remote_image_url) }
its(:list) { should == list }
it { should be_valid }
describe "when list_id not present" do
before { @item.list_id = nil }
it { should_not be_valid }
end
describe "when image not present" do
before { @item.image = "" }
it { should_not be_valid }
end
describe "with blank title" do
before { @item.title = " " }
it { should_not be_valid }
end
describe "with title that is too long" do
before { @item.title = "a" * 141 }
it { should_not be_valid }
end
end
item.rb的
class Item < ActiveRecord::Base
attr_accessible :link, :list_id, :title, :image, :remote_image_url
belongs_to :list
mount_uploader :image, ImageUploader
validates :title, presence: true, length: { maximum: 140 }
validates :list_id, presence: true
validates_presence_of :image
end
我在spec / support / test_images文件夹中有一个名为google.png的图片。
我对rails非常陌生,因此非常感谢任何帮助!

it { should be_valid }
失败,因为(正如您所料)主题无效。你需要找出为什么它是无效的。尝试这样的事情:
it "should be valid" do
subject.valid?
subject.errors.should be_empty
end
现在示例将失败,但错误消息将更具描述性。
另一种方法是将pry添加到您的项目中。然后将binding.pry
添加到您要打开控制台的位置:
it "should be valid" do
subject.valid?
binding.pry
subject.errors.should be_empty
end
现在,您可以检查测试对象,以确定验证失败的方式。

我觉得很蠢。忘了附加图像,这显然导致验证失败。
不得不改变:
before do
@item = list.items.build(title: "Lorem ipsum")
@item.valid?
puts @item.errors.full_messages.join("\n")
end
要:
before do
@item = list.items.build(title: "Lorem ipsum")
@item.image = fixture_file_upload('/test_images/google.png', 'image/png')
end
