硒RC“ driver.quit（）”引發錯誤

Question

我正在將selenium selenium-server-standalone-2.52.0.jar與最新的Firefox版本45配合使用，並遇到以下異常。 一切正常運行了一年以上。 Firefox 45什么問題

Answer 1

在堆棧跟蹤的底部，您可以看到以下內容：

Caused by: java.lang.InterruptedException: null
        at java.lang.ProcessImpl.waitFor(ProcessImpl.java:451)

該文檔告訴您原因：

InterruptedException-如果當前線程在等待時被另一個線程中斷，則等待結束，並拋出 InterruptedException。

我能想到的第一件事是TestNG（或您的其他機制）需要定時等待tearDown完成。

編輯：我剛剛看到，您正在將其與Firefox 45 （Beta版）一起使用。 穩定時間為44.0.2。 Selenium的瀏覽器支持聲明它僅支持已經發布的版本。 至少對於我的英語。

因此，很可能您遇到了Selenium中尚未實現的更改。
