POTD 5: Input Domain Model (IDM) — GenericStack

Due 27-May-2026, 11:59pm EST

---

Purpose: Understand Input Domain Model and derive Input Space Partitioning test inputs. Get ready to work on the learning portfolio.

You may make a copy of a worksheet and complete this activity, or simply type your answers in any text editor.

You may work alone or with another student in this course. (work with your team, feel free to make use of any communication channels of your choice).

---

This is from exercise 6.1, #4 (AO textbook). Derive input space partitioning test inputs for the GenericStack class with the following method signatures:

• public GenericStack ();
• public void push (Object X);
• public Object pop ();
• public boolean isEmpty ();

Assume the usual semantics for the GenericStack. Try to keep your partitioning simple and choose a small number of partitions and blocks.

1. List all of the input variables, including the state variables
   
2. Define characteristics of the input variables. Make sure you cover all input variables
   
3. Partition the characteristics into blocks
   
4. Define values for each block
