*我正在使用Python中的Selenium Webdriver進行WebPage的測試用例自動化。
*我需要驗證在網頁上生成的警報消息。
*使用Webdriver當我嘗試處理警報時,它表示沒有發現警報。即使我沒有處理警報,它也不會給出任何錯誤消息(如生成的未接警報)。
*請建議,爲什麼Webdriver沒有檢測到警報。Python Selenium webdriver:未檢測到生成的警報,也沒有提供錯誤

你可以發佈你正在使用的代碼。您是使用隱式等待函數還是使用更可靠的預期條件等待函數? – duhaime

請給出一些建議...我已經添加了測試用例代碼。 – John

Webdriver按預期工作。 NoAlertPresentException在對未提示的警報窗口執行操作時引發。切換到未出現的警報窗口時不會引發此問題。

所以你的是功能代碼需要對應該警惕的動作:

def is_alert_present(self): 
    try: 
     alert = self.driver.switch_to_alert() # this doesn't raise Exception 
     alert.text # this DOES RISE Exception if there isn't an alert 
     return True 

    except NoAlertPresentException: 
     return False
