Two. More usage of the Android unit test Mockito

A. The simple use of the Android unit test Mockito
Three. Android unit test Powermock assign values to private variables
Four. Android unit test Powermock mock static method

In contrast to the previous article, this article introduces more Mockito usage, and controls Meetingpresenterimp.java and Meetingpresenterimptest.java to see how the Android unit test case is written.
