问题描述

最近发布的Jasmine 2.0删除了等待功能和Async Jasmine 1.3中的 run()

The recently released Jasmine 2.0 removes the waits functions and the runs() from the Async Jasmine 1.3.

我有旧的1.3测试我想转换到新的样式。

I have old 1.3 tests I'd like to transition to the new style.

等待,在大多数情况下,似乎你可以写出 beforeEach() afterEach(),以获得相同的效果。

For the waits, in most cases it seems like you can write beforeEach() and afterEach() carefully for the same effect.

重现 runs()的最佳方法是什么,它只是顺序执行包含的函数?

What is the best way to reproduce the runs() which simply executes the contained functions sequentially?

我的第一次尝试:

runs(function() {
  expect(true).toBe(true);
}

变为

(function() {
  expect(true).toBe(true);
})()


推荐答案

可以在它中使用setTimeout()阻止。

It is possible to use a setTimeout in your it() block.

it("is asynchronous", function(done) {
  var isItDone = false;
  $.ajax('/some/url').success(function() { isItDone = true; });

  setTimeout(function(){
    expect(isItDone).toBeTrue();
    done(); // call this to finish off the it block
  }, 500);

});

然而,我发现这大大减慢了我的测试套件,所以我创建了自己的扩展,重新创建了waitsFor提供的轮询功能。

However, I found that that slowed down my test suite dramatically so I created my own extension which recreates the polling functionality that waitsFor provided.
