Target Function: e-Commerce Discount Logic

Line 1: def calculate_discount(cart_total, is_vip):
Line 2:     discount = 0.0
Line 3:     if cart_total >= 100:       # Decision 1
Line 4:         discount = 0.10
Line 5:     if is_vip:                  # Decision 2
Line 6:         discount += 0.05
Line 7:     return discount

Total Executable Statements: 6 | Total Decision Outcomes (Branches): 4 (Decision 1: True/False, Decision 2: True/False)

Select Test Cases to Execute:
Test 1 (TC1)
cart = 120, vip = True
D1:T, D2:T
Test 2 (TC2)
cart = 50, vip = False
D1:F, D2:F
Test 3 (TC3)
cart = 150, vip = False
D1:T, D2:F
Test 4 (TC4)
cart = 40, vip = True
D1:F, D2:T
Statement Coverage: 100% (6/6)
Branch Coverage: 50% (2/4)
Subsumption Rule: TC1 alone achieves 100% Statement Coverage, but ONLY 50% Branch Coverage!
