承诺后运行规范已经解决 [英] Running spec after promise has been resolved

问题描述

我遇到了运行规范的问题，该规范应在承诺解决后执行。请参阅下面注释的简化示例。

I came across an issue with running a spec that should be executed after a promise has been resolved. See the commented simplified example below.

我尝试使用IIFE或在规范中调用 done（）函数但没有其中似乎有效。

I tried using IIFE or calling done() function in the spec but none of these seemed to work.

// getIds() is a simple promise which returns an array of ids
getIds().then(function (ids) {
    console.log('IDS: ' + ids); // all good so far

    // This test is never run
    it('dummy test', function () { 
        console.log('TEST HAS BEEN RUN');
    });
});

推荐答案

您可以使用浏览器。 wait（）等待你的承诺完成。或者您可以将测试放在then块中：

You can use browser.wait() to wait until your promise is complete. Or you can put your test inside the then block:

it('should test', function() {
  getIds().then(function (ids) {
    // some action.
    expect()...
  });
});

此外，您可以将承诺放在beforeEach或beforeAll（jasmine 2）中。将id分配给describe中声明的变量。该值应该可供您的测试使用。

Also, you can put the promise in a beforeEach or a beforeAll (jasmine 2). Assign the ids to a variable declared inside a describe. The value should be available for your test to use.
