Question

我正在尝试加载Firefox以使用selenium测试我的Web应用程序。我在SessionNotCreatedError: Unable to create new service: GeckoDriverService中指定firefox时出现capabilities错误。这是它的样子：

var config = {
 sauceUser: process.env.SAUCE_USERNAME,
 sauceKey: process.env.SAUCE_ACCESS_KEY,
 framework: 'jasmine2',
 capabilities: {
  browserName: 'firefox',
  version: '57.0', 
  'screenResolution': '1920x1440'
 },
 specs: [
  '*.spec.js'
 ],
  jasmineNodeOpts: {
   showColors: true,
   defaultTimeoutInterval: 300000,
   print: function() {}
 },
  params: {
     defaultTimeout: 15000
 }
};

以下是我的环境的详细信息：

OS: Ubuntu 16.04 LTS 64bit
Firefox: Quantum 57 64 bit
Selenium: 3.7.1
webdriver-manager: 12.0.6
gecko driver: 0.19.1
Protractor: 5.2.0

当我运行我的量角器端到端测试用例时，它会抛出此错误：

我尝试使用 selenium 和 gecko驱动程序的更新版本，但这也无济于事。

我添加了marionette: true，但仍然遇到了同样的错误。我也试过"javascriptEnabled": true, "acceptSslCerts": true但没有成功。

Answer 1

使用geckodriver@1.10.0和Firefox 57.0（64位）时，它对我有用。

Answer 2

请尝试以下解决方案：

DesiredCapabilities caps = DesiredCapabilities.firefox();
caps.setcapabilities("platform","Windows 7"); // you can modify as per your system

caps.setcapabilities("version","57.0"); //modify it to your desired version
caps.setcapabilities("marionette","true");

driver = new RemoteWebDriver(new URL(url), caps); // replace url to your saucelab url

我希望这会有所帮助

Firefox 57在端到端测试期间不会在Selenium中加载geckoservice
