如何等待量角器/茉莉花測試的承諾？

我正在學習量角器（以及擴展名爲茉莉花的量角器使用），並且由於某種原因，我需要等待Promise繼續測試。但是，我不知道該怎麼做。如何等待量角器/茉莉花測試的承諾？

讓我們從量角器教程中的代碼，並添加一些代碼，並讓我們添加一個簡單的承諾（在ES6風格）是不會做任何事情

describe('angularjs homepage todo list', function() { 
    it('should add a todo', function() { 
    browser.get('https://angularjs.org'); 

    element(by.model('todoList.todoText')).sendKeys('write first protractor test'); 
    element(by.css('[value="add"]')).click(); 

    var todoList = element.all(by.repeater('todo in todoList.todos')); 

    Promise.resolve().then(() => { 
     expect(todoList.count()).toEqual(3); 
     expect(todoList.get(2).getText()).toEqual('write first protractor test'); 

     // You wrote your first test, cross it off the list 
     todoList.get(2).element(by.css('input')).click(); 
     var completedAmount = element.all(by.css('.done-true')); 
     expect(completedAmount.count()).toEqual(2); 
    }); 
    }); 
});

這是不行的，因爲這是回答

$ protractor conf.js 
Using the selenium server at http://localhost:4444/wd/hub 
[launcher] Running 1 instances of WebDriver 
F 

Failures: 

    1) angularjs homepage todo list should add a todo 
    Message: 
    Error while waiting for Protractor to sync with the page: "angular could not be found on the window" 
    Stacktrace: 
    undefined 

Finished in 0.212 seconds 
1 test, 1 assertion, 1 failure 

[launcher] 0 instance(s) of WebDriver still running 
[launcher] chrome #1 failed 1 test(s) 
[launcher] overall: 1 failed spec(s) 
[launcher] Process exited with error code 1

我應該怎麼做才能使它工作？

我解決它以下列方式：

第一，使用jasmine2作爲框架，而不是jasemine通過以創作

framework: 'jasmine2'

到conf.js

編輯像這樣的文件

var flow = browser.flow() 

describe('angularjs homepage todo list', function() { 
    it('should add a todo', function() { 
    browser.get('https://angularjs.org'); 

    element(by.model('todoList.todoText')).sendKeys('write first protractor test'); 
    element(by.css('[value="add"]')).click(); 

    var todoList = element.all(by.repeater('todo in todoList.todos')); 

    flow.execute(function(){Promise.resolve()}); 
    // or, more ES6-y version 
    // flow.execute(() => Promise.resolve()); 

    expect(todoList.count()).toEqual(3); 
    expect(todoList.get(2).getText()).toEqual('write first protractor test'); 

    // You wrote your first test, cross it off the list 
    todoList.get(2).element(by.css('input')).click(); 
    var completedAmount = element.all(by.css('.done-true')); 
    expect(completedAmount.count()).toEqual(2); 

    }); 
});

茉莉花實際上是「鏈接」中的承諾，期待一起本身，它方便地解決我的問題。
