Java WebDriverException:未知错误:Runtime.executionContextCreated具有无效的';上下文';:初始化Chrome浏览器时,java,selenium,selenium-webdriver,selenium-chromedriver,Java,Selenium,Selenium Webdriver,Selenium Chromedriver,我正在尝试开始使用selenium,并下载了一个chrome驱动程序并将其放入我的类路径中。我现在只是想得到这个头衔,看看我能不能让它发挥作用。当前代码如下所示: import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class Flows { public static void main(String[] args) { Syste

我正在尝试开始使用selenium,并下载了一个chrome驱动程序并将其放入我的类路径中。我现在只是想得到这个头衔,看看我能不能让它发挥作用。当前代码如下所示:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Flows {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "/Users/mn/Desktop/project/turv/src/main/chromedriver");
        WebDriver driver = new ChromeDriver();
        String baseUrl = "http://google.dk/";
        driver.get(baseUrl);
        System.out.println(driver.getTitle());
        driver.close();
    }
}
我希望我的输出是类似于“谷歌”的东西,但我得到了这个错误:

我真的搞不懂错误是想告诉我什么。是不是因为我在网站完全加载之前就要求标题?是否需要在
getTitle()
之前添加某种
waitforit
命令?

此错误消息

…意味着ChromeDriver无法启动/生成新的网络浏览器,即Chrome浏览器会话

您的主要问题是所使用的二进制文件之间的版本兼容性,如下所示:

  • 您使用的是chromedriver=2.8,这非常古老
  • 您使用的是chrome=66.0
  • 的发行说明明确提到以下内容:
支持Chrome v65-67

因此ChromeDriver版本(v2.8)和Chrome浏览器版本(v66.0)之间存在明显的不匹配

解决方案
  • 将ChromeDriver升级到当前级别
  • 将Chrome版本保持在Chrome v66.x的级别。()
  • 通过IDE清理项目工作区,并仅使用所需的依赖项重建项目
  • 在执行测试套件之前和之后,使用该工具清除所有操作系统杂务
  • 如果您的基本Web客户端版本太旧,请通过卸载它并安装最新的GA和Web客户端发布版本
  • 重新启动系统
  • 执行
    @测试
  • 始终在
    tearDown(){}
    方法中调用
    driver.quit()
    ,以优雅地关闭和销毁Web驱动程序和Web客户端实例

与代码中的任何内容都不一样。您可能需要同时更新chrome和chromedriver。可能是的副本
