Cоnsider this ShоppingCаrt descriptiоn аnd code (shortened): /** * ShoppingCаrt: maintains list of item prices and a running total. * * - addItem(price): adds a price to the cart and updates the total. * - applyDiscount(): If total > 100.0 apply 10% discount (mutates total) and return new total, otherwise just return current total. * (Implementation not shown; treat applyDiscount as black-box behavior.) * - getTotal(): returns the current total. */ public class ShoppingCart { private List prices = new ArrayList(); private double total = 0.0; public void addItem(double price) { prices.add(price); total += price; } // applyDiscount implementation intentionally omitted — treat as black-box public double applyDiscount(); public double getTotal() { return total; } } Part A (1.5 pts): Identify one primary problematic behavior in the implementation and explain briefly why it is problematic. Part B (2 pts): Identify the main equivalence partitions and boundary values you would consider when testing applyDiscount(). Briefly explain why they matter. Part C (2.5 pts): Design 4 test cases for applyDiscount(). For each test specify: initial state (e.g., items added), operations performed, expected result and resulting total. Keep them concise (no code). Part D (1 pt): White-box unit test — write a single JUnit-style pseudocode test for addItem behavior (show test body / assertion), and briefly explain why you chose that test case. Keep answers short and concrete.
