Question

我有一个角度组件，它基本上显示了一个数据库对象列表。由于它们可以处于不同的状态，因此它显示为角度的选项卡视图，其中每个选项卡包含处于特定状态的所有对象。每个对象都有来自后端的id与id=1相关联。如果对象的状态发生变化，则对象会从一个选项卡移动到另一个选项卡。

html的结构看起来像this。

这是使用轮询实现的，并且在角度区域（because of this issue）之外运行：

function startPollingObjects() {
    this.ngZone.runOutsideAngular(() =>
        setInterval(() => {
            this.refreshObjects();
        }, this.pollingFrequency)
    );
}

function refreshObjects() {
    // async call to the backend
    api.getNewObjects.then( data =>
        this.ngZone.run(() => {
            // Run inside zone as the inputs are changed here 
            // so change detection is triggered

            // change data accordingly
            this.list = [];
            for (const row of data) {
                if (!this.list[row.objectState]) {
                    this.list[row.objectState] = [];
                }
                this.list[row.objectState].push(row);
            }
        });
    )
}

我现在要测试的是，对象是否会改变其状态并从一个标签移动到另一个标签。

从UI创建对象（初始状态为state1）
导航到列表
遍历state1选项卡以查找id最大的对象（这是最新创建的对象）*
等待对象出现在另一个标签中（state2）**

*

let lastCreatedObjectId = 0;
await element.all(by.xpath(`//div[@id = 'state1']/*`)).then( async elements => {
        for (const object of elements) {
            await object.getAttribute('id').then( objectId => {
                lastCreatedObjectId = objectId > lastCreatedObjectId ? objectId : lastCreatedObjectId;
            });
        }
        return null; // required as I'm getting this error otherwise https://pastebin.com/AasAZrVY
    });

**

import { by, element, ExpectedConditions as until } from 'protractor';

const object = element(by.xpath(`//div[@id = 'state2' and ObjectAngularComponent/@id = '${lastCreatedObjectId}']`));
    // clicks on the tab to select it
    listObjectStatePage.selectTab(ObjectState.State2);
    browser.wait(until.visibilityOf(object), 20 * 1000).then( () => {
        expect(object).toBeTruthy();
        return null; // required as I'm getting this error otherwise https://pastebin.com/AasAZrVY
    });

- 现在事情变得有趣了 -

只要元素出现在列表中，proctractor就会抛出以下错误。

A Jasmine spec timed out. Resetting the WebDriver Control Flow.

修改：return null; // required as I'm getting this error otherwise https://pastebin.com/AasAZrVY

异步轮询上的量角器测试失败（在jasmine.DEFAULT_TIMEOUT_INTERVAL指定的超时内未调用异步回调）
