6.7. Real-World Example

Let’s say the requirement is: REQ-004: "The user shall be able to add up to 5 items to the wishlist." You should have: ● TC-010: Add 1 item → Success ● TC-011: Add 5 items → Success ● TC-012: Add 6th item → Error displayed All mapped to REQ-004 in the RTM.

In this example, we have a specific requirement (REQ-004) that outlines a functionality in the system: users must be able to add a maximum of five items to their wishlist. To verify this requirement, we have created three test cases:

1. TC-010 checks if adding one item is successful.
2. TC-011 verifies that adding five items works as intended.
3. TC-012 tests the scenario where a user tries to add a sixth item, and it should alert them with an error. This mapping between the requirement and its associated test cases is crucial for ensuring thorough testing.

Imagine a shopping cart in a physical store. If the store adopts a policy that customers can only have up to five items in their cart, it needs to have staff check compliance. Staff members would use scenarios to ensure:

• When a customer adds one item, they successfully can take it into the cart (like adding one item to the wishlist).
• When five items are added, everything works as expected (adding five to the wishlist).
• If the customer tries to add a sixth item, the staff need to inform them that it's against the store policy (the error displayed). This mirrors the RTM process, ensuring no requirement goes unchecked.

All mapped to REQ-004 in the RTM.

Mapping all test cases to a specific requirement in the Requirement Traceability Matrix (RTM) provides clarity about how each aspect of the requirement is tested. This relationship ensures that for every requirement outlined, there is a corresponding check in the form of a test case that confirms its functioning correctly. This practice is essential for quality assurance as it guarantees that no requirement is left untested, thereby reducing the risk of errors in the final product.

Think of it like preparing for a big test at school. You have a study guide (the requirement) that outlines the chapters you need to cover. For each chapter, you might have a practice quiz (test case) to review your understanding. By ensuring each chapter has a quiz linked to it, you can confidently say that you are fully prepared to answer any questions on the test. This structured preparation is similar to how an RTM operates.
