ruby - 以 DRY 方式跨 rspec 规范共享工厂

Question

所以我有一些像这样的模型规范:

describe 'something' do
  it 'another thing' do
    a_model = FactoryGirl.create(:a_model)
    another = FactoryGirl.create(:another)
    #some code using a_model and another 
  end
end

然后，我有另一个模型规范:

describe 'something else' do
  it 'another test' do
    a_model = FactoryGirl.create(:a_model)
    another = FactoryGirl.create(:another)
    #different code using a_model and another 
  end
end

我的问题是如何将其干燥？我查看了共享上下文，但后来无法访问我的模型。我可以创建一个辅助方法并返回对象的数组/散列，但似乎应该内置一些东西以优雅的方式执行此操作。

检查共享上下文:

https://www.relishapp.com/rspec/rspec-core/docs/example-groups/shared-context

# /spec/support/shared_stuff.rb

shared_context "shared stuff" do
  let(:model_1) { FactoryGirl.create(:model_1) }
  let(:model_2) { FactoryGirl.create(:model_2) }
end

然后在你的规范中:

describe "group that includes a shared context using 'include_context'" do
  include_context "shared stuff"

  # ...
end
