(Testing) Answer this question with respect to only the method Push using exactly two characteristics where each characteristic has two blocks in its partition.

2. Derive input space partitioning tests for the GenericStack class with the fol- lowing method signatures: public Genericstack 0; public void Push (0bject x); public object Pop 0; public boolean lsEmt 0; Assume the usual semantics for the stack. Try to keep your partitioning sim- ple, choose a small number of partitions and blocks. (a) Define characteristics of inputs (b) Partition the characteristics into blocks (c) Define values for the blocks
