Question

刚开始使用Jasmine并按照the Jasmine website上的说明进行异步测试时，我注意到从未调用过beforeEach函数。

知道为什么不呢？我在网上的任何地方都找不到任何相关提示。感谢。

代码

代码非常简单：

describe("Testing test.php", function()
{
    it ("Gets me a coke", function()
    {
        var asyncResult = null;

        // query function with callback
        var queryFcn = function(callback)
        {
            console.log("queryFcn");
            $.get("be_com/test.php?coke")
            .success(function(data)
            {
                asyncResult = data.response;
                callback(); // notify jasmine
            })
            .error(function() { callback(); });
        };

        // Call ajax
        beforeEach(function(done) { 
            console.log('beforeEach');
            queryFcn(done); });

        // Evaluate response
        expect(asyncResult).toBe("a can of coke");
    });
});

HTML同样简单：

<html>
<head>
<link rel="shortcut icon" type="image/png" href="../fe_com/js/lib/jasmine-standalone-2.3.4/lib/jasmine-2.3.4/jasmine_favicon.png">
<link rel="stylesheet" type="text/css" href="../fe_com/js/lib/jasmine-standalone-2.3.4/lib/jasmine-2.3.4/jasmine.css">

<script type="text/javascript" src="../fe_com/js/lib/jquery-2.0.0.min.js"></script>
<script type="text/javascript" src="../fe_com/js/lib/jasmine-standalone-2.3.4/lib/jasmine-2.3.4/jasmine.js"></script>
<script type="text/javascript" src="../fe_com/js/lib/jasmine-standalone-2.3.4/lib/jasmine-2.3.4/jasmine-html.js"></script>
<script type="text/javascript" src="../fe_com/js/lib/jasmine-standalone-2.3.4/lib/jasmine-2.3.4/boot.js"></script>

<!--   FILES -->
<script type="text/javascript" src="testSpec.js"></script>
</head>

<body>
    <h2>Unit Tests</h2>
</body>
</html>

beforeEach块不应位于it块内。

beforeEach的想法是，其中的代码在以下每个it块之前运行。例如：

beforeEach(function () { // code in here will run 3 times }); it('does first thing', function () {}); it('does a second thing', function () {}); it('does a third thing', function () {});

Jasmine beforeEach not called
