使用selenium web驱动程序加载chrome浏览器的问题

Question

我无法在Chrome浏览器中运行我的测试.我正在使用selenium-java 2.33.0和java进行编码.

以下是步骤

System.setProperty("webdriver.chrome.driver", "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome");
WebDriver driver  = new ChromeDriver();
driver.get("http://www.google.com");

它会打开Chrome浏览器并抛出以下错误.

我哪里错了？

谢谢,Manoj

请勿使用您浏览互联网的Chrome二进制文件.从Chromedriver网站下载,并在代码中指定路径.

此链接具有更详细解释的解决方案:http://www.gjdb.nl/？p = 214:

如果您想在适用于Mac的WebDriver上运行Chrome,那么根据网站http://code.google.com/p/selenium/wiki/ChromeDriver,您需要指定浏览器到以下位置的路径:"/ Applications/Google\Chrome.app/Contents/MacOS/Google\Chrome".

因此,用于创建ChromeDriver实例的Java代码将是:

System.setProperty("webdriver.chrome.driver", "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome");
driver = new ChromeDriver();

尝试运行时,我得到以下异常.

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
Build info: version: '2.31.0', revision: '1bd294d185a80fa4206dfeab80ba773c04ac33c0', time: '2013-02-27 13:51:26'
System info: os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '10.8.3', java.version: '1.6.0_45'
Driver info: driver.version: ChromeDriver
...

这是我使用ChromeDriver修复的.在http://code.google.com/p/chromedriver/downloads/list上下载您的版本,解压缩并按如下方式使用:

System.setProperty("webdriver.chrome.driver", "<unzip location>/chromedriver");
driver = new ChromeDriver();
