Запуск RSpec на приложение Rails: Когда valid?
вызывается на недопустимый записи, RSpec падает со следующим выходом:Запуск RSpec вызывает неправильный тип аргумента
TypeError:
wrong argument type Hash (expected binding)
EDIT: Проблема была вызвана определение пользовательского метода binding
в app/helpers/application_helper.rb
.
Это очень раздражает, потому что я не могу проверить свои модели.
Рассматривая обратную трассировку, мне кажется, что ошибка не исходит из моего кода приложения.
Я попытался обновить rspec-rails до последней версии и изменить версии i18n gem, а также некоторые другие, которые казались связанными, но немного наугад из-за отсутствия чего-то лучшего. Он продолжал иметь то же самое сообщение. Я искал каждый набор терминов, которые казались мне важными, но не могли найти ничего сопоставимого.
Вы знаете, как исправить или исправить это?
Я не ищу исправления ошибки вне моего кода приложения, а скорее для исправления моей конфигурации, приложения или тестов, если это возникнет.
Ниже приведен тест, демонстрирующий это поведение, команду, обратную трассировку и Gemfile. Заранее благодарю вас за помощь.
Тест:
1 require 'spec_helper'
2 #require 'rspec-expectations'
3
4 describe User do
5 before { @user = FactoryGirl.build(:user)}
6
7 subject { @user }
8
9 it { should be_valid}
10
11 describe "test" do
12 before { @user.email = "a" } #causing the model to be invalid
13
14 it "causes wrong argument type Hash (expected binding)" do
15 puts "here 1"
16 puts @user.method(:valid?).inspect
17 puts @user.valid?
18 puts "here 2"
19 end
20 end
21 end
В консоли, она работает как надо:
R ~/dev/pav/spec rails c test
Loading test environment (Rails 4.1.0)
2.1.0 :001 > user = FactoryGirl.build(:user)
=> #<User id: nil, name: "Example user1", email: "[email protected]", created_at: nil, updated_at: nil, password_digest: "$2a$04$V1znGRLKwr09y2k.QSoL2egSVNkedh22ZWnn1r9B31/...", remember_token: nil, guide: nil>
2.1.0 :002 > user.email = "a"
=> "a"
2.1.0 :003 > user.valid?
User Exists (5.8ms) SELECT 1 AS one FROM "users" WHERE LOWER("users"."email") = LOWER('a') LIMIT 1
=> false
команд, выход и трассировку:
R ~/dev/pav rspec spec/models/user_spec.rb -b
.here 1
#<Method: User(ActiveRecord::Validations)#valid?>
F
Failures:
1) User test causes wrong argument type Hash (expected binding)

i18n - зависимость рельсов-i18n.Снижение рейтинга i18n не помогло. 'method (: binding) .inspect' дает' I18n :: Backend :: Simple (ApplicationHelper) # binding', который кажется нормальным. Спасибо за Ваш ответ! – wacha
Как вы заключаете, что это определение 'binding' является нормальным? Похоже, что это происходит от 'ApplicationHelper', а не от' Kernel', что является нормальным источником его в Rails. –
Я действительно не специалист по этому вопросу. Это казалось мне правдоподобным, потому что оно происходит от драгоценного камня от svenfuchs (который также участвует в rails-i18n), что является зависимостью драгоценного камня I18n в модуле [I18n] (https://github.com/svenfuchs/i18n/blob /master/lib/i18n/backend/base.rb), и потому, что я предполагаю, что RSpec должен сделать некоторые магии для запуска тестов. – wacha
