Safari无法启动新会话。可能的原因是远程服务器地址无效或浏览器启动失败

Question

我正在尝试在Safari上运行我的Selenium测试。我可以在FireFox和IE上运行我的测试，它运行良好，但在Safari上不行。所以可能有人遇到了同样的问题，可以告诉我为什么它不起作用，是的，我已经将WebDriver添加到SafariExtencions：http://prntscr.com/809miw

我有这个错误：

以下是我选择浏览器的方式：

switch(this.type)
        {
            case IE:
                File file = new File(this.config().getParam(ConfigFacade.IEDriverPath_Key));
                System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
                //System.setProperty("webdriver.ie.logfile, ""); // TODO: here somehow redirect log to stream.
                this.driver = new InternetExplorerDriver();
                break;
            case Chrome:
                File chromeFile = new File(this.config().getParam(ConfigFacade.ChromeDriverPath_Key));
                System.setProperty("webdriver.chrome.driver", chromeFile.getAbsolutePath());
                this.driver = new ChromeDriver();
                break;
            case FireFox:
                this.driver = new FirefoxDriver();
                break;
            case Safari:
                this.driver = new SafariDriver();
                break;
            default:
                throw new TestException(String.format("Browser (%1s) is not implemented yet", this.type.toString()));
        }

SafariDriver仅适用于OS X。从您的日志中可以看出，您正在尝试在Windows 7上执行它。您可以在此处查看支持的操作系统和浏览器：http://docs.seleniumhq.org/about/platforms.jsp
