iOS Testing without .ipa file

Is it possible to test the ios application which is already installed on the iPhone, without .ipa file…?
I manage to test this on ANDROID but for iPhone, I don’t have clue how to do it.

Can you help me, please?

Thanks,
Dimitrije

Follow this steps

  1. Remove webDriverAgent and let it reinstall before running the test
  2. Use : capabilities.setCapability(“noReset”, true);
  3. Make sure you are giving correct bundleId of the app already installed.

This is working for me.
