For an online shopping application, ensuring accurate item pricing and total cost calculations in the shopping cart is crucial for functionality and user trust. Unit testing focused on verifying these aspects is essential during development.
* A. Verify the data page has the correct item prices: This test ensures that the prices pulled from the external inventory management system into the application via the data page are accurate. Correct item pricing is foundational to calculating the total cost for items in the shopping cart.
* D. Verify the order total cost property is accurately calculated: This test checks whether the application correctly calculates the total cost of all items in the shopping cart, considering both the individual item prices and their quantities. Accurate total cost calculation is crucial for the final order summary and checkout process.
Verifying the data transform copies the correct value (B) is important for data integrity but is a more granular detail compared to the overarching need to ensure accurate pricing and total calculations. Verifying the price fields are displayed in the correct format (C) is also significant but focuses more on UI presentation than on the underlying functional correctness of pricing and total cost calculations.
