Question

使用karma-webdriver-launcher和＆karma-selenium-grid-launcher尝试了Karma，以启动chrome / firefox执行测试，但无法打开浏览器

有人可以分享使用硒网络驱动程序和业力进行e2e测试的工作代码吗，在Google上进行了搜索，但仅在这些代码段中找不到完整的代码。

我的业力配置文件::

 module.exports = function (config) {
var webdriverConfig = {
    hostname: 'localhost',
    port: 4444,
  }


let customLaunchers = {

    firefoxCustom: {
        base: 'WebDriver',
        config: webdriverConfig,
        browserName: 'firefox',
        version:'ANY',
        platform:'ANY'
      },

};

config.set({
  basePath: './',
  frameworks: ["mocha"],
  reporters: ['progress'],

  plugins: [
    'karma-webdriver-launcher',
  'karma-selenium-grid-launcher',
  'karma-mocha',
  'selenium-webdriver'
],


  customLaunchers: customLaunchers,
  browsers: [ 'firefoxCustom'],
  files: [
    "tests/*.spec.js"
  ],
  singleRun: true
});
}

测试文件::

const {Builder, By, until} = require('selenium-webdriver');

(async function example() {
const driver = await new Builder().forBrowser('firefox').build();

try {
    await driver.get('https://www.google.com');
    await driver.findElement(By.name('q')).sendKeys('hello');
    await driver.findElement(By.id('tsf')).submit();
}catch(err)
{
    console.log(err)
} 
finally {
    await driver.quit();
}
})();

package.json

我通过Docker在Selenium和Standalone Chrome上运行。相同的方法也可以在Docker外部运行，但这意味着您自己设置Chrome，Chromedriver和Selenium Hub，这本身就很麻烦。

karma.conf.js

module.exports = function karmaConfig(config) {

    config.set({
        frameworks: ['jasmine'],
        files: [
            // src files
            // spec files
        ],
        exclude: [],
        preprocessors: {},
        reporters: ['dots'],
        port: 9876,
        logLevel: config.LOG_INFO,
        autoWatch: false,
        singleRun: true,

        // RELEVANT BIT
        browsers: ['ChromeWebDriver'],
        customLaunchers: {
            ChromeWebDriver: {
                base: 'WebDriver',
                browserName: 'chrome',
                version: 'ANY',
                platform: 'ANY',
            }
        },
        captureTimeout: 60000,
        // END RELEVANT BIT
    });

};

package.json（可能有点过时）：

"karma": "1.3.0",
"karma-jasmine": "0.1.6",
"karma-webdriver-launcher": "1.0.7",

我在主机网络docker run -d --network=host selenium/standalone-chrome:3上使用Docker运行Selenium，这暴露了http://127.0.0.1:4444/wd/hub。然后，我等到Selenium Hub响应后再启动karma.conf.js。

日志：

> karma start tests/javascript/karma.conf.js

我没有设置customLauncher.ChromeWebDriver.config，因为我匹配了默认的Selenium Hub位置。 This also matches the default in wd，这是karma-webdriver-launcher使用的软件包。

Karma：无法使用karma-webdriver-launcher启动浏览器
