Module: Price Calculation
TC_ID_PRICE_01
Title: Verify total price is calculated correctly for valid inputs
Preconditions: Product/service available
Steps:
Enter quantity and unit price
Calculate total
Test Data: Quantity = 2, Unit Price = 100
Expected Result: Total = 200
TC_ID_PRICE_02
Title: Verify calculation with decimal unit price
Preconditions: Decimal pricing allowed
Steps:
Enter quantity and decimal price
Test Data: Quantity = 3, Unit Price = 99.99
