如何在 RSpec 中包含 Rails Helpers [英] How to include Rails Helpers on RSpec
问题描述
我正在尝试包含一些助手来使用 rspec 进行测试,但没有运气.
I'm trying to include some helpers to test with rspec but no luck.
我做了什么:
在我的 spec
文件夹下创建了一个 support/helpers.rb
文件.
created a support/helpers.rb
file under my spec
folder.
support/helpers.rb
module Helpers
include ActionView::Helpers::NumberHelper
include ActionView::Helpers::TextHelper
end
并试图在 spec_helper.rb
中要求这个文件.
and tried to require this file in 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
这会产生以下错误:
/spec/support/helpers.rb:2:in `<module:Helpers>': uninitialized constant Helpers::ActionView (NameError)
我应该如何做这个助手才能在 Rspec 中可用?
How should I do this helpers to be available with Rspec?
谢谢.
推荐答案
一旦 Rails 堆栈可用,我通常会包含此代码以要求我的 spec/support
子目录下的所有内容:
I normally include this code to require everything under my spec/support
subdirectory once the Rails stack is available:
Spork.prefork do
# ...
Dir[Rails.root.join('spec', 'support', '**', '*.rb')].each { |f| require f }
RSpec.configure do |config|
config.include MyCustomHelper
# ...
end
end
请注意,这将在所有示例类型(控制器、模型、视图、助手等)中包含 MyCustomHelper
.您可以通过传递一个 :type
参数来缩小范围:
Note that this will include MyCustomHelper
in all example types (controllers, models, views, helpers, etc.). You can narrow that down by passing a :type
parameter:
config.include MyControllerHelper, :type => :controller
