硒瀏覽器何時自動死亡？

Question

我們創建了許多使用硒的測試套件。當我們單獨執行它們時，它們都成功運行。但是，當我們嘗試運行整個套件時，瀏覽器隨機死亡，我們收到以下錯誤消息。

據我所知，代碼中沒有錯誤。因此，請讓我知道，在什麼情況下硒網格自動殺死瀏覽器。

Answer 1

Error communicating with the remote browser. It may have died.此錯誤來自某些原因。

1）意外的是瀏覽器在一段時間後會關閉或者你的網格機器也會這樣做。

2）driver.close();在完成執行之前調用。

• 可能是你在課後寫driver.close();。

3）driver.quite();也有同樣的問題，因爲2點

4）請檢查您的驅動程序實例啓動處處完美。
