As I find StartApplication that uses location of the .apk/.ipa, can we use the package and/or application name instead? If we can, how to structure it? Especially if the apps are developed in the past/by third party. ---

Currently it is not possible to do in Katalon Studio. You need to have your application file to be used. ---

Is it possible to test that an application such as the generic iOS Mail application has opened? (I am using my application to send an email and want to use Katalon to test that the mail client has, in fact, opened). Thanks!
