How to include Rails Helpers on RSpec
提问by Kleber S.
I'm trying to include some helpers to test with rspec but no luck.
我正在尝试包含一些助手来使用 rspec 进行测试，但没有运气。
What I did:
我做了什么：
created a support/helpers.rbfile under my specfolder.
support/helpers.rb在我的spec文件夹下创建了一个文件。
support/helpers.rb
支持/helpers.rb
module Helpers
include ActionView::Helpers::NumberHelper
include ActionView::Helpers::TextHelper
end
and tried to require this file in spec_helper.rb.
并试图在spec_helper.rb.
# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'rubygems'
require 'spork'
require 'support/helpers'
Spork.prefork do
.
.
end
this generates the following error:
这会产生以下错误：
/spec/support/helpers.rb:2:in `<module:Helpers>': uninitialized constant Helpers::ActionView (NameError)
How should I do this helpers to be available with Rspec?
我应该如何做这个助手才能与 Rspec 一起使用？
Thanks.
谢谢。

I normally include this code to require everything under my spec/supportsubdirectory once the Rails stack is available:
spec/support一旦 Rails 堆栈可用，我通常会包含此代码以要求我的子目录下的所有内容：
Spork.prefork do
# ...
Dir[Rails.root.join('spec', 'support', '**', '*.rb')].each { |f| require f }
RSpec.configure do |config|
config.include MyCustomHelper
# ...
end
end
Note that this will include MyCustomHelperin all example types (controllers, models, views, helpers, etc.). You can narrow that down by passing a :typeparameter:
请注意，这将包含MyCustomHelper在所有示例类型（控制器、模型、视图、助手等）中。您可以通过传递:type参数来缩小范围：
config.include MyControllerHelper, :type => :controller

Simply include the Module you need directly in the spec file:
只需将您需要的模块直接包含在规范文件中：
include PostsHelper
