webdriver-io - WebdriverIO 在尝试运行测试时出错

问题描述

我在运行我的 WebdriverIO 测试时遇到问题，我认为这与我如何处理在公司代理后面运行有关。过去一切正常，但突然它们停止了，在尝试了几个小时后，我已经没有想法了。

http_proxy我的代理详细信息以和的名称保存为 Windows 系统变量https_proxy。我没有改变这些。我用于变量的格式是这样的 - http://myusername:mypassword@myproxyaddress:8080。

通过外部连接连接到互联网时，我也会遇到错误，所以我不是 100% 是它的代理造成的。

我已经尝试更新我的所有包，所以我的包文件现在看起来像这样：

{
  "name": "name",
  "version": "1.0.0",
  "description": "UI Tests",
  "main": "index.js",
  "scripts": {
    "test": "node_modules/.bin/wdio ./wdio.conf.js"
  },

  "license": "ISC",
  "devDependencies": {

    "@wdio/local-runner": "^5.18.6",
    "@wdio/mocha-framework": "^5.18.6",
    "@wdio/selenium-standalone-service": "^5.16.10",
    "@wdio/spec-reporter": "^5.18.6",
    "@wdio/sync": "^5.18.6",
    "chai": "^4.2.0",
    "chai-webdriverio": "^1.0.0",
    "chromedriver": "^79.0.3",
    "local-runner": "^0.1.1-alpha",

    "webdriver": "^5.18.6"
  },
  "dependencies": {
    "@wdio/cli": "^5.18.6"
  }
}

我的 wdio.conf.js 文件在这里（从实际文件中删除了注释）：

exports.config = {

    specs: [
        './test/**/*.js'
    ],
    // Patterns to exclude.
    exclude: [
        // 'path/to/excluded/files'
    ],

    maxInstances: 10,

    capabilities: [{

        maxInstances: 5,

        browserName: 'chrome'

    }],

    logLevel: 'trace',

    bail: 0,

    baseUrl: 'https://apps-dev.bhp.com/moc/',

    waitforTimeout: 15000,

    connectionRetryTimeout: 90000,

    connectionRetryCount: 3,

    services: ['chromedriver','selenium-standalone'],

    framework: 'mocha',

    reporters: ['spec','dot'],

    mochaOpts: {
        ui: 'bdd',
        timeout: 120000
    },


    beforeTest: function (test, context) {
        const chai = require('chai')
        const chaiWebdriver = require('chai-webdriverio').default

        chai.use(chaiWebdriver(browser))

        global.assert = chai.assert
        global.should = chai.should
        global.expect = chai.expect

    },

}

当我运行测试时我的终端：

PS C:\Test Automation\Projects\WebdriveriO\GlobalMoC> npm test -- --spec ./test/login.test.js

> globalmoc@1.0.0 test C:\Test Automation\Projects\WebdriveriO\GlobalMoC
> wdio ./wdio.conf.js "--spec" "./test/login.test.js"

解决方案

由于您尝试在代理后面使用 selenium 独立服务，因此您应该在配置文件中包含以下设置。这对我有用。我已经包含了一些你可以参考的文件。

skipSeleniumInstall: false,
  seleniumInstallArgs: {
    requestOpts: {
      strictSSL: false,
      timeout: 10000,
      proxy: proxyurl,
    },
  },

https://webdriver.io/docs/selenium-standalone-service.html#skipseleniuminstall
