if I have multiple streams I reduce into 1, producing some sort of a FooStateObject which is a tuple of x values
data class FooStateObject(showA: boolean, showB: boolean, showC: boolean) etc
how do you test this without combinatorial explosion, when each of the propeties depends on different values?
for example
imagine showA is

val showSomeOverlay = callState is Active && callMediaState is Video.Activated

a concrete example (edited)
so testing when showSomeOverlay is true is obviously easy
but should one test for the false as well? I think so, in order for it to be complete,i.e. someone might ad a new && branch etc.

so true = 2 combinations, but false = many combinations, as there are many more values in those two enums...
