ruby-on-rails - RSpec 测试失败，方法未定义 `validate_uniqueness_of'

Question

使用 Rails 5 和 RSpec 3.5，我收到以下错误。

  1) User
     Failure/Error: it { should validate_uniqueness_of(:auth_token)}

     NoMethodError:
       undefined method `validate_uniqueness_of' for #<RSpec::ExampleGroups::User:0x007fab919f8cf
8>
     # ./spec/models/user_spec.rb:14:in `block (2 levels) in <top (required)>'

我用谷歌搜索了正确的语法，但找不到解决方案。有谁知道在这里使用什么？谢谢

您必须将 gem 添加到 Gemfile 中:

gem 文件

group :test do
  gem 'shoulda-matchers'
end

并包含它:

spec/rails_helper.rb

RSpec.configure do |config|
  config.include(Shoulda::Matchers::ActiveModel, type: :model)
  config.include(Shoulda::Matchers::ActiveRecord, type: :model)
end
