PhantomJSDriver和FirefoxDriver之间的区别

Question

我正在尝试编写需要在HTTPS中执行GET请求的集成测试，测试将在远程服务器中运行。哪个驱动程序会更好，我怎么能设置它？当我做driver.get时，它会永远卡在那里。

capabilities = new DesiredCapabilities();
capabilities.setJavascriptEnabled(true);
capabilities.setCapability("takeScreenshot", true);
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
capabilities.setCapability("phantomjs.page.settings.userAgent",
            "Mozilla/5.0 (Unknown; Linux i686) AppleWebKit/534.34 (KHTML, like Gecko) Safari/534.34");
driver = new PhantomJSDriver(capabilities);
