我正在为其中一个应用程序在 webdriverio 中编写一些测试。我启动 selenium 服务器并运行以下命令

./node_modules/.bin/wdio wdio.conf.js

当我在旧的 windows 计算机上运行它时,它工作得很好,现在我有了一个新的 mac,它失败了。以下是堆栈跟踪

A service failed in the 'onPrepare' hook

    // Specify Test Files
    // ==================
    // Define which test specs should run. The pattern is relative to the directory
    // from which `wdio` was called. Notice that, if you are calling `wdio` from an
    // NPM script (see https://docs.npmjs.com/cli/run-script) then the current working
    // directory is where your package.json resides, so `wdio` will be called from there.
    //

        './test/specs/*.js'

    exclude: [
        // 'path/to/excluded/files'
    ],
    //
    // ============
    // Capabilities
    // ============
    // Define your capabilities here. WebdriverIO can run multiple capabilities at the same
    // time. Depending on the number of capabilities, WebdriverIO launches several test
    // sessions. Within your capabilities you can overwrite the spec and exclude options in
    // order to group specific specs to a specific capability.
    //
    // First, you can define how many instances should be started at the same time. Let's
    // say you have 3 different capabilities (Chrome, Firefox, and Safari) and you have
    // set maxInstances to 1; wdio will spawn 3 processes. Therefore, if you have 10 spec
    // files and you set maxInstances to 10, all spec files will get tested at the same time
    // and 30 processes will get spawned. The property handles how many capabilities
    // from the same test should run tests.
    //
    maxInstances: 10,
    //
    // If you have trouble getting all important capabilities together, check out the
    // Sauce Labs platform configurator - a great tool to configure your capabilities:
    // https://docs.saucelabs.com/reference/platforms-configurator
    //
    capabilities: [{
        // maxInstances can get overwritten per capability. So if you have an in-house Selenium
        // grid with only 5 firefox instances available you can make sure that not more than
        // 5 instances get started at a time.

我在 wdio.conf.js 文件中尝试了以下方法

方法一:小写手册

 proxy: {
        proxyType: "manual",
        httpProxy: "http://domain:port"
    }

方法2:大写手册

 proxy: {
        proxyType: "MANUAL",
        httpProxy: "http://domain:port"
    }

方法 3:使用 http:// 代理

 proxy: {
        proxyType: "MANUAL",
        httpProxy: "http://domain:port"
    }

方法4:没有http://的代理

 proxy: {
        proxyType: "MANUAL",
        httpProxy: "http://domain:port"
    }

你能告诉我问题是什么吗,我也尝试在终端会话中添加代理,它仍然是一样的

此错误消息...

Could not request headers from https://chromedriver.storage.googleapis.com/2.43/chromedriver_mac64.zip: Error: read ECONNRESET

...意味着ChromeDriver无法启动/生成新的WebBrowser ,即Chrome 浏览器会话。

您的主要问题是您使用的二进制文件版本之间的不兼容,如下所示:

  • 您正在使用chromedriver=2.43
  • chromedriver=2.43的发行说明清楚地提到了以下内容:

支持Chrome v69-71

  • 大概您使用的是最新的chrome= 76.0
  • ChromeDriver v76.0的发行说明清楚地提到了以下内容:

支持Chrome 版本 76

所以ChromeDriver v2.43Chrome Browser v76.0之间存在明显的不匹配


解决方案

确保这件事:

  • ChromeDriver已更新到当前的ChromeDriver v76.0级别。
  • Chrome已更新到当前的Chrome 版本 76.0级别。(根据ChromeDriver v76.0 发行说明
  • 通过IDE清理项目工作区并仅使用所需的依赖项重建项目。
  • 如果您的基本Web 客户端版本太旧,请卸载并安装最新的 GA 和已发布版本的Web 客户端
  • 重新启动系统
  • @Test非 root用户身份执行。
