RSpec：我如何将模块混合到RSpec测试中？

In my app when user share something he's rating grows. When he tries to share something twice – he will get no additional rating for second try. For application, share callback is triggered by client-side with JS, so, it's just a regular GET-request. So, I need to test this functionality. It's easy. But I'v got several sections with this behavior. Every controller from that sections have method named "rating_from_share", so tests are pretty similar. I think it is good idea to extract that test's in a mixing and include them where it should be, but I can't figure out, how can I do this. So, is it real to include a mixing with RSpec to a RSpec test? Maybe something kind of metaprogramming can solve this problem?

在我的应用程序中,当用户分享他的评级增长的东西。当他试图分享两次东西时 - 他会在第二次尝试时没有获得额外的评分。对于应用程序,共享回调是由客户端用JS触发的,因此,它只是一个常规的GET请求。所以,我需要测试这个功能。这很容易。但我有几个部分有这种行为。该部分的每个控制器都有名为“rating_from_share”的方法,因此测试非常相似。我认为最好在混合中提取测试并将它们包含在应有的位置,但我无法弄清楚,我该怎么做。那么,将RSpec与RSpec混合测试包含在内是真的吗?也许某种元编程可以解决这个问题?

P.S. realization of "rating_from_share" method is not really the same but only the output result, so I can't to aggregate it to a superclass and test them here.

附: “rating_from_share”方法的实现并不是真的相同而只是输出结果,所以我不能将它聚合到一个超类并在这里测试它们。

EDIT:

According to Vimsha answer, should I do something like this?

根据Vimsha的回答,我应该这样做吗?

Module Share
  def share
    it 'should be fun'
      expect(@fun.isFun?).toBe == 'yup' # the @fun is declared in ShareTest
    end
  end
end

describe "Share Test" do
   extend Share
   before :each do
     @fun = Fun.new
   end
   it 'should do test' do
     share # call method from Share module, which has real RSpec code?
   end
end

The code is written just here, I'm just trying to get the idea.

代码就是在这里编写的,我只想尝试一下。

3 个解决方案

#1

module Share
  def share
  end
end

describe "Share Test" do
   extend Share
end

You can call the methods of the module directly within the tests

您可以在测试中直接调用模块的方法

#2

You can use shared examples.

您可以使用共享示例。

These are typically saved under spec/support and loaded via spec_helper.rb. Be sure to read the docs to understand how to load the shared code--it is not automagically performed for you.

这些通常保存在spec / support下并通过spec_helper.rb加载。请务必阅读文档以了解如何加载共享代码 - 它不会自动执行。

Once they are defined you can include them like so:

一旦定义它们,您可以像这样包含它们:

# spec/support/decorated_model.rb
shared_examples "decorated_model" do
  it "can be decorated" do
    subject.should respond_to?(:decorate)
  end
end

# my_class_spec.rb
describe MyClass do
  it_behaves_like "decorated_model"
end

#3

A common practice in RSpec is to store such logic under spec/support. For instance:

RSpec的一个常见做法是将此类逻辑存储在spec / support下。例如:

# spec/support/ratings_macros.rb
module RatingsMacros
  ...
end

You then need to load it from your spec_helper:

然后,您需要从spec_helper加载它:

# spec/spec_helper.rb
...
RSpec.configure do |config|
  ...
  config.include RatingsMacros

You can now call in your tests all the methods defined in the RatingsMacros module.

您现在可以在测试中调用RatingsMacros模块中定义的所有方法。

module Share
  def share
  end
end

describe "Share Test" do
   extend Share
end
