java - org.openqa.selenium.WebDriverException : chrome not reachable

Question

尝试进行一些 Java Selenium 训练测试，但我在运行 Web 驱动程序时遇到问题... 我的代码非常简单，但它不起作用。 我正在使用 macOS Sierra 版本 10.12.3。

我的代码是:

import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.junit.Assert;

/**
 * Created by wizzz-mac on 08/02/2017.
 */
public class FirstTest {

    @Test
    public void startWebDriver(){
        System.setProperty("webdriver.chrome.driver", "/Users/wizzz-mac/Downloads/chromedriver");
        WebDriver wd = new ChromeDriver();
        System.out.println(wd.getTitle());
        wd.close();
        wd.quit();
    }
}

这是 pom.xml :

这是我得到的错误:

我认为问题在于以下部分:

Answer 1

其他答案没有解决问题 - 我的解决方案非常简单:我只是重新安装了 Chrome(不是 chromedriver)并且 - 它有效。
