option1: separate test project for Android
option2: "Project inside the project", folder "tests"
option2
should provide better eclipse speed, visibility and less maintenance,
promoted by google in the documentation
BUT currently has the ADT wizard support function.
I am currently considering option1 as a valid de facto standard,
and he has good ADT support.
Keep your eyes open because ADT versions are almost released monthly
therefore option 2 may soon become actual.
