Question

我正在尝试在OS X上使用chrome运行selenium测试。它可以与firefox一起使用，但Chrome驱动程序似乎与浏览器无法通信。

这是我的代码：

import junit.framework.TestCase;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class DriverTest extends TestCase {

    public void testFirefox(){
        FirefoxDriver driver = new FirefoxDriver();
        driver.get("http://www.google.com");
        driver.close();
    }

    public void testChrome(){
        ChromeDriver driver = new ChromeDriver();
        driver.get("http://www.google.com");
        driver.close();
    }    
}

当我运行它时，firefox启动正常，但对于chrome我得到这个错误：

Answer 1

您需要指定指向Chromedriver位置的系统属性，例如：

System.setProperty("webdriver.chrome.driver", "applications/chrome/chromedriver");

第二个参数应设置为保存chromedriver的路径。

Answer 2

尝试为ChromeDriver设置DesiredCapabilities.chrome（）。

ChromeDriver driver = new ChromeDriver(DesiredCapabilities.chrome());

这应该有用。

ChromeDriver无法与OS X上的浏览器通信
