org.openqa.selenium.NoSuchSessionException：无法在 docker 容器中使用 Behat/Mink 和 Selenium2Driver 找到 ID 错误测试的会话

Man*_*olo 6 selenium symfony behat selenium-chromedriver docker

我正在尝试使用 Behat /Mink和Selenium2Driver测试 Symfony3 Web 应用程序，以便我也可以测试 Javascript 功能。

在码头工人容器中的应用程序运行，所以增加了对硒毂和铬新搬运工容器如所描述的在这里：

并执行测试，200 秒后抛出此错误：

PHP 致命错误：在 null 上调用成员函数 click()

我确定缺少某些东西，但不知道是什么。任何的想法？

最可能的原因是您使用的二进制文件版本之间不兼容。

解决方案

确保这件事：

  • ChromeDriver更新到当前ChromeDriver v84.0级别。
  • Chrome已更新到当前的Chrome 版本 84.0级别。（根据ChromeDriver v84.0 发行说明）
  • 如果您的基本Web 客户端版本太旧，请卸载它并安装最新的 GA 和发布版本的Web 客户端。
  • 进行系统重启。
  • 始终driver.quit()在tearDown(){}方法内调用以优雅地关闭和销毁WebDriver和Web Client实例。
