使用Selenium Ruby Webdriver运行脚本时，浏览器关闭然后在完全关闭之前打开几次

我在运行Selenium Ruby Webdriver脚本时遇到问题，如下所示：

Selenium完成运行我的脚本后，浏览器将关闭（这是预期的行为）。然而，紧接着，浏览器重新打开，什么也不做，然后关闭，连续地，浏览器重新打开，然后关闭。在浏览器（FF16或IE9或Chrome）完全关闭之前，此操作会重复大约4次

每次打开和关闭浏览器时，都会显示以下日志消息 关闭请注意，我正在使用@driver.quit关闭浏览器。 请帮助我做一些我需要做的事情来克服这个问题 不方便的情况。非常感谢

发生此问题的原因是我在脚本中使用“test_3;”前缀命名了一些函数。只需从这些函数的名称中删除“test_”前缀，问题就解决了
