我在迈克尔·哈特尔的Rails教程的第7.2.2节(第7章)中,当我向app/controllers/users_controller.rb
添加@user变量时,事情变得奇怪。原本应该通过的测试不会 - 它们会因为不同的原因而失败:
$ rspec spec/requests/user_pages_spec.rb -e "signup page"
Failures:
1) User pages signup page
Failure/Error: before { visit signup_path }
ActionView::Template::Error:
undefined method `users_path' for #<#<Class:0x007fdec372a8e0>:0x007fdec375d010>
# ./app/views/users/new.html.erb:6:in `_app_views_users_new_html_erb___2884421820517152565_70297369620580'
# ./spec/requests/user_pages_spec.rb:8:in `block (3 levels) in <top (required)>'
2) User pages signup page
Failure/Error: before { visit signup_path }
ActionView::Template::Error:
undefined method `users_path' for #<#<Class:0x007fdec372a8e0>:0x007fdec45caee0>
# ./app/views/users/new.html.erb:6:in `_app_views_users_new_html_erb___2884421820517152565_70297369620580'
# ./spec/requests/user_pages_spec.rb:8:in `block (3 levels) in <top (required)>'
最初,这些测试失败b / c @user是nil。现在他们由于未定义的方法而失败。
这本书表明,一旦我定义了@user,它们应该通过,所以我很困惑。我已经向前推了一下,想也许这会自行解决,但事实并非如此,所以我想在继续之前弄清楚这一点。
以下是有问题的测试(从书中复制):
require 'spec_helper'
describe "User pages" do
subject { page }
describe "signup page" do
let(:user) { FactoryGirl.create(:user) }
before { visit signup_path }
it { should have_selector('h1', text: 'Sign up') }
it { should have_selector('title', text: full_title('Sign up')) }
end
end
答案 0 :(得分:1)
从头开始重新开放项目我遇到了一个不同的错误,导致我在config/environments/test.rb
发现了这个错字:
# Speed up tests by lowering BCrypt's cost function. require 'bcrypt'
silence_warnings do
BCrypt::Engine::DEFAULT_COST = BCrypt::Engine::MIN_COST
end
通过将require 'bcrypt'
移动到它自己的行,一切都会再次起作用 - 包括原始问题中的测试。
# Speed up tests by lowering BCrypt's cost function.
require 'bcrypt'
silence_warnings do
BCrypt::Engine::DEFAULT_COST = BCrypt::Engine::MIN_COST
end
