刚开始使用 Jasmine 并按照 the Jasmine website 上的说明进行操作对于异步测试，我注意到从未调用过 beforeEach 函数。
知道为什么不吗？我在网络上的任何地方都找不到任何相关的提示。谢谢。
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:

最佳答案
beforeEach block 不应位于 it block 内。
beforeEach 的想法是，它内部的代码在以下每个it block 之前运行。示例:
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 () {});
关于javascript - Jasmine beforeEach 未调用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30657626/
