Rspec-core: RSpec::ExampleGroups 的未定义方法“控制器”

创建于 2014-05-20 · 3评论 · 资料来源: rspec/rspec-core

从rspec-rails (3.0.0.beta2)为rspec-rails (3.0.0.rc1)

规格

require 'spec_helper'
describe ApplicationController do
  controller do
    def index
      render :text => 'Ok'
    end

    def show
      raise TypeError, 'Any fake value!'
    end
  end

  it "redirects to new_sessions_path" do
    get :index
    expect(response).to redirect_to(new_session_path)
  end
end

错误

rspec-rails 2.x 有一些非常隐含的（对某些人来说是“神奇的”）行为，它会根据文件位置推断规范类型。在 RSpec 3（从 RC1 开始）中，如果需要，您需要选择加入，或者自己设置规范类型：

describe ApplicationController, :type => :controller do
end

# or

RSpec.configure do |config|
  config.infer_spec_type_from_file_location!
end

有关更多信息，请参阅 rspec/rspec-rails#970。

对于执行 2.14 -> 2.99 -> 3.0 升级路径的人，有明确的弃用警告，但不幸的是，3.0 beta2 -> 3.0 RC1 不会触发。对于那个很抱歉！
