Test function points

• Click on the main interface MainActivity button Button to jump to another interfaceOtherActivity

Test method

• Use Instrumentation , perform a Click button action, determine whether the activity of the interface after the jump is expected activity
• Use ActivityMonitor , this class is used to monitor a single activity in an application, monitoring some specified intent.
• Once the instance is created, ActivityMonitor the instance is added by calling the Instrumentation.addMonitor method, and when the target activity starts, the system matches the list of Activitymonitor instances in the instrumentation, and if it matches, it accumulates the counter
