java - 使用 selenium 网络驱动程序加载 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。

步骤如下

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

它打开 chrome 浏览器并抛出以下错误。

Exception in thread "main" 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.

请勿使用浏览互联网时使用的 Chrome 二进制文件。从 Chromedriver website 下载，并在您的代码中指定路径。

此链接更详细地解释了解决方案:http://www.gjdb.nl/?p=214 :

When you want to run Chrome on WebDriver for your Mac, then according to according to the site http://code.google.com/p/selenium/wiki/ChromeDriver you will need to specify the path to the browser to the following location: “/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome”.

So the Java code for creating a ChromeDriver instance will be:

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

When trying to run this I got the following exception.

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
...

This I fixed by using the ChromeDriver. Download your version on http://code.google.com/p/chromedriver/downloads/list, unzip it and use it as followed:

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