Ember測試失敗

Question

我在我的應用程序上運行'ember test --server'，出現兩次失敗，我不知道它們爲什麼失敗。

從CLI：

> ToUrlHelper: it works 
>  ✘ Died on test #1  at eval (new-cms/tests/unit/helpers/to-url-test.js:10:5) 
>   at requireModule (http://localhost:7357/assets/vendor.js:70:29) 
>   at http://localhost:7357/assets/test-loader.js:14:29: undefined is not a function 

從Web瀏覽器：

> Died on test #1  at eval 
> (new-cms/tests/unit/helpers/to-url-test.js:10:5) 
>  at requireModule (http://localhost:7357/assets/vendor.js:70:29) 
>  at http://localhost:7357/assets/test-loader.js:14:29: undefined is not a function Source:  TypeError: undefined is not a function 
>  at Object.eval (new-cms/tests/unit/helpers/to-url-test.js:11:20)

這是在對URL的test.js：

import { 
    toUrl 
} from 'new-cms/helpers/to-url'; 

module('ToUrlHelper'); 

// Replace this with your real tests. 
test('it works', function() { 
    var result = toUrl(42); 
    ok(result); 
}); 

從代碼實際幫手：

import Ember from 'ember'; 

export default Ember.Handlebars.makeBoundHelper(function(value) { 
    if(typeof(value) !== 'undefined') { 
     return value.replace(/\s+/g, '-').toLowerCase(); 
    } 
    return ''; 
}); 

Answer 1

也許這不過是你將42傳遞給你的函數，然後試圖對其應用.replace函數。但是這個函數只能在字符串上定義...

首先傳入一個字符串，例如「hello me」而不是42，然後在另一個測試中傳遞42，查看您的測試中斷，因爲您的實現沒有考慮到這一點並修復您的實施。 （這是有點測試驅動開發）
