篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Rails无法加载shoulda-matchers 3.1.1 gem,undefined方法`allow_value'代表#相关的知识,希望对你有一定的参考价值。
运行rspec测试时,'shoulda-matchers'的gem没有加载。
错误:NoMethodError: undefined method 'allow_value' for #<RSpec::ExampleGroups::Contact::ActiveModelValidationss:0x007fef1021b310>
正在使用的版本:Ruby 2.2.2
Rails 4.2.1
shoulda-matchers 3.1.1
的Gemfile:
source 'https://rubygems.org'
gem 'rails', '4.2.1'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'

gem 'rubocop', require: false
end
rails_helper.rb:
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'spec_helper'
require 'rspec/rails'
ActiveRecord::Migration.maintain_test_schema!

contact_spec.rb:
require 'spec_helper'
describe Contact do
FactoryGirl.define do
factory :contact do
first_name "Alice"
last_name "Bob"
email_address "alicebob@example.com"
phone_number "555-555-5555"
company_name "ExampleCompany"
end
end
it "has a valid factory" do
expect(build(:contact)).to be_valid
end
describe "ActiveModel validations" do
it { expect(:contact).to allow_value("alice_bob@example.com").for(:email_address) }
end
end
对不起,所有的代码。请注意我使用的是shoulda-matcher版本3.1.1,并且不再需要将'require:false`添加到gemfile中,如此处所示https://robots.thoughtbot.com/shoulda-matchers-3-0
我也尝试在Gemfile中将shoulda-matchers添加到自己的测试环境中,但是没有发现任何变化
group :test do
gem 'shoulda-matchers', '~> 3.1'
end
我已经在线查看,并发现类似的问题解决方案在我的情况下不起作用。任何帮助或建议都会很棒!
在我的情况下,问题是测试类不是ActiveRecord
项目,所以shoulda
默认情况下没有加载allow_value
等方法。
解决方案是在type: :model
文件中添加_spec.rb
:
RSpec.describe MyTestedClass, type: :model do
...
end
应该让你再次变绿的修复方法是改变:
it { expect(:contact).to allow_value("alice_bob@example.com").for(:email_address) }
至
it { expect(build(:contact)).to allow_value("alice_bob@example.com").for(:email_address) }
以与第一次测试相同的方式,因为您的第二个测试期望符号:contact
到allow_value
,而不是您工厂中创建的对象。
此外,我建议将您的工厂定义移动到spec/factories/contact.rb
下的自己的文件中,而不是在您的规范中内联,并在let
方法中记住联系对象,因此您的规范如下所示:
require 'spec_helper'
describe Contact do
let(:contact) { build(:contact) }
it "has a valid factory" do
expect(contact).to be_valid
end
describe "ActiveModel validations" do
it { expect(contact).to allow_value("alice_bob@example.com").for(:email_address) }
end
end
