加载角度SPA时的org.openqa.selenium.TimeoutException

Question

我正在使用chimp.js,它通过一些光纤魔法来增强webdriver.io,以便可以以同步方式定义代码.这是代码:

var c = require('./config');

module.exports = function () {
    this.When(/^I try to login with wrong credentials$/, function () {
        browser.setValue(userNameField, wrongUser);
        browser.setValue(passwordField, wrongPassword);
        browser.click('button[value="Login"]');
    });
    this.When(/^I try to login with the correct credentials$/, function () {
        browser.setValue(userNameField, c.userName);
        browser.setValue(passwordField, c.password);
        console.log('before pressig the button');
        browser.click('button[value="Login"]');
        console.log('logged in');
    });
};

第一个When执行得很好.第二个When也有效,我只是没有看到

登录

在控制台上.两者都在同一个网站上运行,并且都点击了同一个按钮.在第二种情况下,登录成功后,浏览器将重定向到角度SPA.这里的一切都正确加载,但就是这样.回调永远不会发生.

用--debug --log=command我运行测试看到这是最后一行(在超时之前)

[1;30m[01:30:18]: [0m [0;35mCOMMAND [0mPOST      "/wd/hub/session/7c334efe-2417-4184-b43c-082ba4441291/element/11/click"

将日志级别切换为详细,并等待〜5min我收到以下错误:

对于要加载的SPA的第一页,要初始化的数据,...(铬停止显示页面正在加载)平均需要3-7秒.超时设置为10秒,所以我想增加它,通过

module.exports = function () {
    this.BeforeScenario(function () {
        browser.timeout('script', 60 * 1000);
        browser.timeout('page load', 60 * 1000);
    });
};

但这也没有帮助.知道我能做什么/尝试？

只是为了再次澄清 - 登录页面是一个简单的静态服务器端呈现HTML.用户登录后,会将其重定向到SPA,该SPA基于Angular 1.4.按下具有错误凭据的登录按钮可能会起作用,因为我没有被重定向到SPA,而是返回到登录页面.

所有测试都在Chrome OS中运行,在Mac OS X El Capitan上运行

更新:

现在它工作了一次.之后我注意到,当我重新加载网站时,脚本会继续运行,以防它被卡住.

这里的页面以这种方式工作:

• / 访问页面并初始化角度
• ui-router路由到 #/defaultroute
• 控制器初始化并下载一些初始数据
• 新控制器在内部初始化ng-repeat并下载更多数据

所以是的,它有相当多的数据下载并等待整个页面显示出来.也许这会给chimp.js或webdriver.io带来麻烦？

当然,从切换browser.click(...);到browser.key(['Enter']);也不起作用.卡住和重新加载浏览器的相同问题修复了它.似乎silenium可能没有得到页面实际完成加载.这就是重新加载页面的原因.知道怎么解决这个问题吗？

顺便说一句,我也提出了一个问题:https://github.com/xolvio/chimp/issues/165

更新2:

在Firefox和PhantomJS中它起作用,Safari根本不运行.

也许在这一点上我只想知道错误在哪里,如果它是一个已知的bug,......

Answer 1

我会做什么来缩小问题范围：

1. 单独运行单个失败测试（以确保其他测试不会以某种方式产生影响）

2. 直接访问失败的测试最终（重定向）URL，而不是通过单击按钮。例如（类似browser.get('#/defaultroute')）；

3. 检查angular页面是否不执行polling（连续 setTimeout、间隔），这可能被视为页面未加载/同步（怀疑它，因为它在刷新时起作用）
