錯誤：找不到契約的工件

我是乙太坊開發的新手，並嘗試SimpleStorage使用松露測試合約：

我使用創建了文件結構turffle init，這是文件結構：

~/Desktop/truffle-test$ tree .
.
├── build
│   └── contracts
│       └── SimpleStorage.json
├── contracts
│   └── SimpleStorage.sol
├── migrations
│   └── 3_deploy_simpleStorage.js
├── test
│   └── simpleStorage-test.js
└── truffle-config.js

我simpleStorage-test.js的是：

const simpleStorage = artifacts.require('../contracts/SimpleStorage.sol');

contrcat('SimpleStorage', ()=> {
   it('should update data', async ()=> {
       const storage = await simpleStorage.new();
       await storage.set(10);
       const data = await storage.get();
       assert(data.toString()==='10');
   });
}); 

我可以遷移契約，我看到交易出現在 Ganache-GUI 上，但是當我執行時，truffle test我得到：

我嘗試了不同的方法，例如SimpleStorage 代替../contracts/SimpleStorage.solintartifacts.require 但沒有解決問題。所以感謝你的幫助。

您的程式碼中有錯字。替換contrcat為contract。該變數由 truffle 框架定義。
