RSpec :: ExampleGroups的未定义方法define_enum_for

Question

将4.1从4.1升级到4.2.0后，我得到undefined define_enum_for method error。

有没有解决这个问题？

Rails：4.2.0

Ruby：ruby 2.1.5p273（2014-11-13修订版48405）[i686-linux]

     Failure/Error:
       should define_enum_for(:state).
         with({
           initial: 'initial',
           running: 'running',
           stopped: 'stopped'
         })

     NoMethodError:
       undefined method `define_enum_for' for #<RSpec::ExampleGroups::Recording:0x99a0ea8>

shoulda-matchers#define_enum_for

Answer 1

为shoulda-matcher指定test_framework :rspec＃配置解决了这个问题。

shoulda-matchers#configuration

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    with.test_framework :rspec

    with.library :active_record
    with.library :active_model
    with.library :action_controller
  end
end

Answer 2

需要配置

1. spec_helper.rb / rails_helper.rb配置块
2. 类型：元数据

spec_helper.rb / rails_helper.rb

我需要spec_helper.rb中的Shoulda :: Matchers配置（该应用程序尚未迁移到rails_helper.rb-但如果可用，rails_helper.rb是我会放置的位置）：

# spec/spec_helper.rb
Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    with.test_framework :rspec
    with.library :rails # same as :active_record + :active_model + :active_controller
  end
end

元数据

但是，它还需要type:元数据才能起作用：

This==============\/
describe User, type: :model do
  it { should define_enum_for(:status) }
end
