As it is common now, the correct architecture should contain decoupled layers. Inter-layer communication between them is done by streams, or in our case, flows, in Android. To make our solutions foolproof, we should create tests around every component, and the ViewModel is no exception. The more cha...

Those traits are what the author calls “the four pillars of a good unit test”. And the interesting part is that we cannot maximize all of them. Some types of tests provide the best protection against regression and resistance to refactoring but with very slow feedback (like UI testing). ...
