javascript - 尝试运行 QUnit 测试但找不到明确定义的函数

问题描述

我已经在我正在运行的测试中调整了这个例子

https://embed.plnkr.co/plunk/OJpuhX

在测试中，导入功能失败，但我找到了解决方法。

这是该示例中的代码块：

索引.html

    <!DOCTYPE html>
    <html>

    <head>
        <link data-require="qunit@*" data-semver="1.17.1" rel="stylesheet"
            href="http://code.jquery.com/qunit/qunit-1.17.1.css" />
        <script data-require="qunit@*" data-semver="1.17.1" src="http://code.jquery.com/qunit/qunit-1.17.1.js"></script>
    </head>


    <body>
        <div id="qunit"></div>
        <div id="qunit-fixture"></div>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/require.js/2.3.6/require.min.js"></script>
        <script src="hello.js"></script>
        <script src="hello.test.js"></script>
    </body>

    </html>

添加.js

export class showAlert {
    static msg() {
        alert('Hello World!');
        // retmsg = 'Hello World!'
        // return retmsg;
    }
}

你好.test.js

import ('hello.ts');

QUnit.test("hello test", function (assert) {
    assert.ok(hello.hello() === 'Hello World!', 'Passed!');
});

hello.ts（以前的 hello.js），如果它是 ts 由于 IMPORT 不能在模块之外工作，我无法导入

var hello: any;

import { showAlert as _alert } from './add';

   hello = function hello() {
      alert('MakeTest: ' + _alert);
      return 'Hello World!';
   };
   alert('Hello var: ' + hello);

我经常得到的错误是：
