Unit test SparseArray using JUnit (using JVM)

Question

I have an implementation which is using a Integer as key in HashMap. It is already unit tested using JUnit. But I want to change it to SparseArray which is more optimised version from Android. I am not sure how will it be unit tested using JUnit. Does anyone have a better way to do this?

Answer 1

There's an equivalent implementation of SparseArray in Support Library called SparseArrayCompat that can be used in JVM Unit Tests. Also it has more features than the native one, so you're better off using that.
