In my application, if session of one user already exists, and the same user tries to create new session via new browser window then a Javascript alert is displayed to warn the user. Now, this alert is displayed only if the session already exists, so I have to accept it and continue login. Is there any method available in karate core to handle this scenario? I am aware of dialog(true) method to handle such alerts but, here I need to check explicitly if alert is present and then handle it. Is there any way to do that?
