How can I test the unit test Legato app on the mangOH Red development board? I know we can upload the app to the mangOH Red and start the app with app start. But how can I fetch the app status is failed or not? ---

Probably you need to understand the program flow and read if there is error message ---

Is there another way to read the app message from the logread? ---
