Xcode中的測試鏈接器錯誤

Question

我沿着關於使用來自TDD site的xcode/appcode構建測試的說明。我完成了最初的部分，並開始在自己的項目中進行實驗，但是我一直收到鏈接錯誤，無法找出從哪裏來的？

我得到的輸出是這樣的

ld: symbol(s) not found for architecture i386 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

我試圖尋找丟失的來源或鏈接庫，但找不到任何東西。任何人都知道還有什麼可能是錯的？

謝謝！
