Question

我在运行Selenium无头时出现间歇性故障服务器使用xvfb。它大部分时间都可以工作，但是大约10％的运行失败并显示此消息：

[06:35:05] I/direct - Using FirefoxDriver directly...

我正在运行Selenium Webdriver 2.53.0

我的配置（使用Mozilla Firefox 46.0.1）：

exports.config = {
    framework: 'jasmine2',
    directConnect: true,
    specs: ['specs/*.js'],
    capabilities: {
        browserName: 'firefox'
    },
    jasmineNodeOpts: {
        defaultTimeoutInterval: 40000,
        showColors: false
    }
};

测试只是打开一个浏览器：

describe('Home page flow test', function() {
    it('should load home page', function() {
        browser.get('https://www.google.com');
    });
});

我正在使用此命令运行Protractor：

xvfb-run --server-args="-screen 0 1024x768x24" protractor --verbose

谢谢！
