有時webdriver的運行過程中停止和警告「沒有會話」 /「沒有窗戶目標」和等。的webdriver並不穩定，有時會崩潰時正在運行的
我用的量角器節點。 JS用於我的自動化測試。
錯誤不是Constantine，有時候所有的200個測試用例都可以正常工作，直到運行結束。

請幫我弄清楚爲什麼會發生什麼更好的解決辦法，以避免它..
感謝。
這是僅在Chrome中發生的嗎？你在Firefox嘗試過嗎？你有沒有嘗試升級量角器？謝謝。 – alecxe
嗨@alecxe，實際上IDK，因爲我不能再使用FF了，還有一些最新版本的問題，量角器現在無法在這個瀏覽器上運行..我也應該解決這個問題。 IE在打字時工作緩慢，並延緩了運行。所以，它可能不會發生，只能通過Chrome，但我不確定它。 –
