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：

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 () {});
