随后从GroovyConsole对Geb Spock Test的调用以UnreachableBrowserException失败

Question

我正在GroovyConsole.exe中运行下面的脚本(GebreportingSpec测试用例）。第一次启动GroovyConsole时，它可以正常运行。它打开FF，运行场景，然后在退出浏览器时关闭FF。

但是，当我再次从相同的GroovyConsole运行相同的脚本时，我会得到unreachableBrowserException。它首先调用setupspec()方法，然后在调用测试用例中的go方法时，调用cleanupspec()······

Answer 1

Geb有一个驱动程序缓存的概念，因此只打开和重用一个浏览器窗口，在groovy控制台中使用它会遇到问题。Geb为您管理驱动程序/浏览器实例，并且缓存在虚拟机的整个生命周期中处于活动状态。之所以出现错误，是因为您正在手动退出驱动程序（如果启用了驱动程序缓存，就不应该这样做），并且VM尚未关闭（groovy控制台仍在两次执行之间运行），这意味着从缓存中检索到的驱动程序管理的浏览器已经关闭。

你有两个选择，第二个在我看来更好：

• 不要退出驱动程序-将打开一个浏览器窗口，并在测试的后续执行中重用
• 使用构建系统，例如Gradle（这里有一个使用Gradle构建的示例Geb项目）-这将在执行测试后关闭VM，并自动关闭浏览器
