【问题标题】：Protractor Error first time - Jasmine spec timed out. Resseting WebDriver Control Flow第一次量角器错误 - Jasmine 规范超时。重置 WebDriver 控制流
【发布时间】：2018-02-07 17:51:32
【问题描述】：

今天我醒来并尝试像往常一样使用量角器运行E2E 测试并显示错误消息：

'茉莉花规格超时。正在重置 WebDriver 控制流'。

我想指出，在使用与往常相同的规格之前从未发生过这种情况。这对我来说没有任何意义。有什么想法吗？让我分享我的配置：

var HtmlReporter = require('protractor-html-screenshot-reporter');

var today = new Date(),
timeStamp = today.getMonth() + 1 + '-' + today.getDate() + '-' + today.getFullYear() + '-' + today.getHours() + 'h-' + today.getMinutes() + 'm';

var reporter = new HtmlReporter({
baseDirectory: '../test_out/e2e',
docTitle: 'Protractor Reporter',
docName: 'protractor-tests-report-' + timeStamp + '.html',
takeScreenShotsOnlyForFailedSpecs: false
});

【问题讨论】：

尝试增加你的 jasmine defaultTimeoutInterval: 2*60*1000，开发端可能会有所改变。当它阻塞需要时间来执行并且超出定义的时间（在您的情况下为 60 秒）时，就会出现此错误。

标签： selenium jasmine protractor

【解决方案1】：

allScriptsTimeout 设置为 15 秒，jasmine defaultTimeoutInterval 设置为 60 秒。这意味着如果某个异步调用花费的时间超过 15 秒，或者如果“it”语句运行时间超过 60 秒，jasmine 将终止测试并抛出此错误消息Jasmine spec timed out。

您的应用程序发生了变化，以至于您的测试运行速度比以前慢（增加超时间隔以使测试再次通过，或解决应用程序的性能问题），或者测试挂在某个地方并卡住了.

【解决方案2】：

当我们遇到测试突然停止工作的问题时，通常是 chrome 版本和 chromedriver 不匹配。 Chrome 会自动更新，默认情况下它的 webdriver 不会。

检查驱动版本

您可以通过找到您的 chromedriver 可执行文件并打开它来检查，这应该会显示一个版本。
查看Chrome driver version

现在请务必检查here，如果您当前版本的 chromedriver 与您的 chrome 版本兼容。如果没有：

更新 chromedriver

您可以简单地用正确的版本覆盖 chromedriver 可执行文件。

如果您使用 webdriver manager，chromedriver 可以保持自动更新。

This NPM package will auto update the needed drivers
