linux - 错误未知错误 : missing or invalid 'entry.level' while executing Nigthwatch. js

Question

您好，我正在尝试对我的 stagin 环境运行基本测试。相同的通用测试适用于谷歌，但不适用于我的暂存环境。这是测试:

browser.url('https://google.com')
.execute(function () {

    alert('this works');

});

当我在我的个人环境中运行这个测试时，我得到这个错误:

我怀疑它是 cors 或 ssl 问题，但无法确认。

感谢任何线索。如果我找到答案，我会张贴在这里。

错误说明了一切:

INFO Response 200 POST /wd/hub/session/104d0fe3600f4da9b8deddf0adc06b42/url (3064ms) { sessionId: '104d0fe3600f4da9b8deddf0adc06b42',
  status: 13,
  value: { message: 'unknown error: cannot determine loading status\nfrom unknown error: missing or invalid \'entry.level\'\n  (Session info: chrome=64.0.3282.186)\n  (Driver info: chromedriver=2.29.461571 (8a88bbe0775e2a23afda0ceaf2ef7ee74e822cc5),platform=Linux 4.13.0-36-generic x86_64)' } }

从您的错误堆栈跟踪中可以清楚地看出 Chrome 浏览器 session 未初始化。

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

• 您正在使用 chromedriver=2.29
• chromedriver=2.29 的发行说明明确提到以下内容:

Supports Chrome v56-58

• 您正在使用 chrome=64.0
• chromedriver=2.35 的发行说明明确提到以下内容:

Supports Chrome v62-64

因此 ChromeDriver v2.29 和 Chrome 浏览器 v64.0 之间明显不匹配

解决方案

• 将 ChromeDriver 升级到最新级别 chromedriver=2.36 .
• 将 ChromeBrowser 升级到最新级别 chrome=65.x。
• 清理您的项目工作区，通过您的IDE 并重建您的项目，仅使用所需的依赖项。
• 使用CCleaner用于在执行您的测试套件之前和之后清除所有操作系统杂务的工具。
• 如果您的 ChromeBrowser 基础版本太旧，请通过 Revo Uninstaller 卸载它。并安装最新的 GA 和发布版本的 ChromeBrowser。
• 执行你的@Test。
