> Hi all, Guys need your help. Anyone has the experience working with custom capabilities for appium server? For e.g. For tests that should be tested on test environment I need to set the custom capability for the appium server that starts the app pointing on test environment, for production - to production. I heard that in iOS app it possible to build the project if the url comes with for ex. test environment, API switches to the test environment, if other value - to other API. Thanks a lot…
