8. You are testing a simplified apartment search form which has only two search criteria:

• floor (with three possible options: ground floor; first floor; second or higher floor)
• garden type (with three possible options: no garden; small garden; large garden)

14. You are testing a web application that allows users to SEARCH for products, VIEW product details, ADD products to a shopping cart, and place an ORDER.
You have prepared the following five test cases, which you want to execute according to their priorities:

TC1: SEARCH product A Priority: medium

TC2: VIEW product A details Priority: low

TC3: ADD product B to a shopping cart Priority: medium

TC4: ADD product C to a shopping cart Priority: high

TC5: place an ORDER Priority: high

You also identified the following logical dependencies between test cases:

• SEARCH functionality must be tested before VIEW functionality can be tested, as product details rely on search functionality.
• VIEW functionality must be tested before ADD functionality, as adding products relies on the availability of accurate product details.
• ADD functionality must be tested before ORDER functionality, as placing an order relies on the availability of accurate shopping cart information.
