Answer 1

RSpec不知道您的规范是控制器规范,因此您的示例无法访问get方法.

RSpec 2.x假定控制器目录中的所有内容都是控制器规范.

这在RSpec 3中有所改变:

默认情况下禁用文件类型推断

以前我们自动从文件位置推断出spec类型,这对于新用户来说是一个令人惊讶的行为,对于一些资深用户来说是不可取的,所以从RSpec 3开始,必须明确选择这种行为:

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

https://www.relishapp.com/rspec/rspec-rails/docs/upgrade#file-type-in​​ference-disabled

在rspec-rails自述文件中:

控制器规格默认驻留在spec/controllers folder.使用元数据标记任何上下文:type => :controller将其作为控制器规范的示例处理.

为RSpec设置控制器上下文元数据的示例:

describe ToolsController, :type => :controller do
    # ...
end

Answer 2

如果你正在使用'spec/features',你可能需要在'spec_helper.rb'中添加以下内容

config.include RSpec::Rails::RequestExampleGroup, type: :feature

Answer 3

在Rspec 3.x中,不会从文件位置自动推断规范类型,您必须手动设置它,将其添加到spec_helper.rb

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

Rspec升级

Answer 4

通过添加require 'rspec/rails'到我的spec_helper文件,我能够在我的应用中修复此问题.

Answer 5

对于其他人来说.我试图追查undefined method 'get'错误.我的问题是,我有get一个describe block确保你get是在it block.

Answer 6

通过替换线解决
describe PagesController do与 RSpec.describe PagesController, :type => :controller do
在_spec.rb在规范文件夹文件.
另外要防止弃用警告使用expect(response).to be_success而不是response should be_success.
PS:没必要添加require "rails_helper".
