Espresso - How to check if one of the view is displayed

Question

In my test, after one action, there are two possible views which can appear and both of them are correct. How can I check if one of the view is displayed. For a single view I ca

Answer 1

When I face this situation I generally split into multiple tests. One test sets the conditions for view #1 to be displayed and the other test sets the conditions for view #2 to be displayed.

But let's say that you can't really control the conditions. For example, what if it depends on a random number or it depends on a third-party resource such as a calculation on a server? In that case, I usually solve the problem mocking. That way I can control the conditions so I know exactly which view to expect. I use Dependency Injection to set the mock I need for each test.
