Question

我正在跑步＆＃39; ember test --server＆＃39;在我的申请中，我遇到两次失败，我不确定他们为什么会失败。

从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

从网络浏览器：

这是to-url-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);
});

来自实际帮助者的代码：

import Ember from 'ember';

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

也许这只不过是你将42传递给你的函数，然后尝试在其上应用.replace函数。但是这个函数只在字符串...

上定义

首先传入像＃34; hello me＆＃34;而不是42，然后在另一个测试中传递42，看看你的测试中断，因为你的实现没有考虑到这一点并修复你的实现。（这是一种测试驱动开发）
