Question

我正在尝试测试以下代码：

<div name="userElem" *ngFor="let user of users ; let i=index">
    <div class="list-group-item" id="user-{{i}}" (click)='selectUser(user)' [style.backgroundColor]="user?._id==selectedUser?._id ? '#F0F0EE' : 'white'">
        <div *ngIf="user?._id==selectedUser?._id">      
            <div class="pull-right">        
                <a  id="delete-user-{{i}}" (click)="deleteUser(user._id)">  
                    <i class="fa fa-trash fa-fw"></i>
                </a>
                <a  (click)="editUser(user._id)">
                   <i class="fa fa-pencil fa-fw"></i>
                </a>
                <a [routerLink]="['/edit',user._id]" name="userLink-{{i}}">
                    <i class="fa fa-eye fa-fw"></i>
                 </a>
             </div>
          </div>
        </div>
    </div>

使用低于E2E测试用例：

it('should delete a user', () => {
    page.navigateToUserComponent();  
    let selectUserElem = element(by.id('user-0')).click();   //this event is fired as I can see user getting selected.    
    let deleteUserElem = element(by.id('delete-user-0'));    
    browser.wait(function() {
        return browser.isElementPresent(by.id('delete-user-0'));
    }, 5000);
    expect(deleteUserElem.isPresent()).toBeTruthy();  // if element is present I want to click that element .i.e. delete the first user in array
  });

但到目前为止没有取得任何成功。

我尝试了多个方法，如以下链接所述：

但无法使其发挥作用。有什么帮助吗？

Answer 1

使用ExpectedConditions和browser.wait()使您的脚本等待某些条件：

var EC = protractor.ExpectedConditions;
var elm = element(by.id('delete-user-0'));

browser.wait(EC.presenceOf(elm), 5000);

Answer 2

如果要识别第一个delete_user元素，可以使用以下xpath。

let deleteUserElem = element.all(by.xpath(".//a[contains(@id, 'delete-user-')]")).first();

然后你可以将它与量角器预期条件联合起来，等到所需的web元素出现。

EC = protractor.ExpectedConditions;
browser.wait(EC.presenceOf(deleteUserElem),20000, 'element is not visible within the time specified');

Answer 3

您使用的是socket.io吗？如果您在应用中使用socket.io，似乎存在量角器不起作用的错误：https://github.com/angular/angular/issues/11853。
