selenium-webdriver - session 未在 Protractor 中为 chrome 创建异常

Question

尝试针对 chrome 运行 Protractor 测试时出现以下错误。

我的conf.ts

import {Config} from 'protractor'

export let config: Config = {
    framework: 'jasmine',
    // capabilities: { browserName: 'chrome'},
    multiCapabilities: [
        // {browserName: 'firefox'},
        {
            browserName: 'chrome',
            chromeOptions: {
                args: ['--start-maximized']
            },

        }],

    seleniumAddress: 'http://127.0.0.1:4444/wd/hub',
    seleniumPort: null,
    seleniumArgs: [],
    specs: [
        './Protractor/Login/*.spec.js',

错误:

conf.ts

multiCapabilities: [

        {
            browserName: 'chrome',
            chromeOptions: {
                args: ['--start-maximized']
            },

        }],

网络上的大部分讨论都是围绕版本展开的。我目前使用的是最新版本

有什么线索吗？

干杯

Answer 1

您可以通过更改 Protractor 的 config.json 文件来更改 webdriver-manager 下载的 chromedriver 的版本...

1. 编辑 Protractor 的配置文件:node_modules/protractor/config.json
2. 将 Chrome 驱动程序版本更改为您需要的任何版本。例如。 “chromedriver”:“2.24”。
3. 运行 webdriver-manager 更新。

根据您发布的错误，protractor 未使用最新的 chrome 驱动程序版本。在堆栈跟踪中，它显示 chrome 驱动程序版本为 2.21。
