Detailed explanation-1: -All Definition Strategy (AD) the ‘all definitions strategy’ reveals that every definition of every variable be covered by at least one use of that variable; be it the use a computational use or a predicate use.

Detailed explanation-2: -All Uses Startegy (AU):The all uses strategy is that at least one definition clear path from every definition of every variable to every use of that definition be exercised under some test.

Detailed explanation-3: -A definition-clear path with respect to a variable x is a path between two nodes A and B, being x defined in A, with an use in B and there is no other definition of x in the other nodes present in the path between A and B. <

Detailed explanation-4: -Term: “definition-use pair”. A definition-use pair is the association between the definition of a variable and the use of the variable. Uses of variables include operations (such as multiplication) or direction (execution/route) of a path (use of “predicate”).
