Question

我正在尝试为新项目设置Protractor。我们的要求包括对大多数流行浏览器（Chrome，Firefox，IE，Safari）的端到端测试。

设置Chrome测试15秒后，我已经卡住了一整天，试图让Firefox驱动程序正常工作。这是我目前的配置：

exports.config = {
  allScriptsTimeout: 11000,
  specs: [
    './e2e/**/*.e2e-spec.ts'
  ],
  multiCapabilities: [
    {
      browserName: 'chrome',
      chromeOptions: {
        args: ['--headless', 'no-sandbox', '--disable-gpu',
          '--window-size=1200x900']
      }
    },
    {
      browserName: 'firefox'
    }
  ],
  directConnect: false,
  chromeDriver: './node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.37',
  firefoxPath: './node_modules/protractor/node_modules/webdriver-manager/selenium/geckodriver-v0.20.0',
  seleniumAddress:
    'http://localhost:4444/wd/hub',
  baseUrl:
    'http://localhost:4200/',
  framework:
    'jasmine',
  jasmineNodeOpts:
    {
      showColors: true,
      defaultTimeoutInterval:
        30000,
      print:
        function () {
        }
    }
  ,
  onPrepare() {
    require('ts-node').register({
      project: 'e2e/tsconfig.e2e.json'
    });
    jasmine.getEnv().addReporter(
      new SpecReporter({spec: {displayStacktrace: true}}));
  }
}

问题是，我收到以下错误：

SessionNotCreatedError: Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line

我已经完成了webdriver-manager update并且所有驱动程序都存在于node_modules中。它们无法被发现或使用。

这是ng e2e的整个输出：

有人有任何提示吗？

Answer 1

原来我没有安装Firefox（浏览器本身）。我错误地确信安装的驱动程序是浏览器的独立版本，但它实际上只是一个包装器。

Answer 2

multiCapabilities: [{ 'browserName': 'chrome' }, { 'browserName': 'firefox' }],

对于chrome，firefox，无需添加驱动程序/ exe文件简化multiCapabilities我们添加浏览器名称。

量角器没有为Firefox找到GeckoDriver
