The command allows you to launch applications in run time.
|BundleId (iOS) / Application Activity (Android)||string||The app to be launched|
true - instrumented
false - non-instrumented
true - will stop the app if it was already running
Following the install command, you would want to launch the app anytime during the test. Note that the launch command complements the install command but does not rely on it. The launch command lets you launch any application given that you know the BundleId (iOS), or App Package and App Main Activity (Android).
