有什麼方法可以從rspec代碼的每一行中刪除主題？

Question

我想刪除每行主題，它使我的天賦太冗長，

我的模型具有下面的代碼： -

形容「#clone_for_resubmit」做

let(:new_item) { @order_item1.clone_for_resubmit(:cart_group => @cart_group, :cloned_collections => { }, :order => @cart_group.order, :message => "this is just for testing purpose", :receiver => "example@example.com", :sender =>"ragarwal@kreeti.com") } 
subject{ new_item} 
it "should clone an order_item" do 
    gift = FactoryGirl.create(:gift, :order_item_id => @order_item1.id, :user => @user) 
subject.cart_group.should == @cart_group 
    subject.collection.name.should == @order_item1.collection.name 
    subject.collection.book.title.should == @order_item1.collection.book.title 
    subject.collection.user.should == @order_item1.collection.user 
    subject.collection.book.book_chapters.count.should == @order_item1.collection.book.book_chapters.count 
    subject.collection.book.book_chapters.last.chapter_title.should == @order_item1.collection.book.book_chapters.last.chapter_title 
    subject.collection.items.last.user_recipe.recipe.name.should == @order_item1.collection.items.last.user_recipe.recipe.name 
subject.collection.book.book_chapters.last.items.last.user_recipe.recipe.name.should == @order_item1.collection.book.book_chapters.last.items.last.user_recipe.recipe.name 
    subject.gift.recipient_email.should == gift.recipient_email 
    subject.gift.message.should == "this is just for testing purpose" 
    subject.gift.receiver.should == "example@example.com" 
    subject.gift.sender.should == "ragajhk@vy.com" 
    subject.payment.payment_amount.should == @order_item1.payment.payment_amount 
    subject.payment.order.should == @cart_group.order 
end

大衛Chelimsky描述implicit use of 'subject' as a code smell，所以你是正確的想擺脫它。但是你it塊做了太多這是會大量反正影響您的規範的可讀性 - 以使其更具可讀性，我建議做一些更象下面：

describe Order do 
    describe '#clone_for_resubmit' do 
    before do 
     # @user = ... 
     # @order_item1 = ...   
     # @cart_group = ...   
     @new_item = @order_item1.clone_for_resubmit(:cart_group   => @cart_group, 
                :cloned_collections => { },              
                :order    => @cart_group.order, 
                :message   => "this is just for testing purpose", 
                :receiver   => "example@example.com", 
                :sender    =>"ragarwal@kreeti.com") } 

     @gift = FactoryGirl.create(:gift, :order_item_id => @order_item1.id, :user => @user) 
    end 

    it 'should use the correct cart group' do 
     @new_item.cart_group.should == @cart_group 
    end 

    it 'should use the correct collection name' do 
     @new_item.collection.name.should == @order_item1.collection.name 
    end 

    it 'should use the correct book title' do 
     # etc... 
    end 
    end 
end 

這樣，你不僅會有更多可讀的規格，它們也會更好地失敗 - 如果有一件事出錯，其他的依然是綠色的。
