要求在 PhantomJs 测试中失败

Question

我有一个简单的库，

-- src/lib.js --
function libtest() {
    return 2;
}

我想测试的，我收集到的需要 PhantomJs。我有一个测试文件：

-- test/lib.test.js --
var fs = require('fs');
var assert = require('assert');
describe('Test module', function() {
    var s = fs.readFileSync('../src/lib.js', 'utf8');
    eval(s);
    it('Shows name', function() {
        assert.equal(libtest(), 2);
    });
});

我为浏览器准备的：

# browserify lib.test.js -o tests.js

然后在我的主页中包含：

-- test/index.html --
<html>
<head>
  <meta charset="utf-8">
  <title>Mocha Tests</title>
  <link href="../../node_modules/mocha/mocha.css" rel="stylesheet" />
</head>
<body>
  <div id="mocha"></div>
  <script src="../../node_modules/mocha//mocha.js"></script>
  <script>mocha.setup('bdd')</script>
  <script src="tests.js"></script>
  <script>
    if (window.mochaPhantomJS) mochaPhantomJS.run();
    else mocha.run();
  </script>
</body>
</html>

然而，当我运行测试时：

# grunt test

我收到以下错误：

Running "mocha_phantomjs:all" (mocha_phantomjs) task TypeError: 'undefined' is not a function (evaluating 'fs.readFileSync('../src/lib.js', 'utf8')')

Domains, protocols and ports must match.

这似乎是在抱怨 fs 未定义。但是，如果 require('assert') 起作用，我想 require('fs') 应该起作用。但我不太清楚这是运行.

的上下文

我错过了什么？

好的。答案只是将库包含在 .html 中。由于在浏览器中进行了测试运行，因此该库将可用。像这样：

<body>
  <div id="mocha"></div>
  <script src="../../node_modules/mocha//mocha.js"></script>
  <script>mocha.setup('bdd')</script>
  <script src="../../src/lib.js"></script>
  <script src="tests.js"></script>
