When defining a system testing policy for an interactive system, which of the following should be tested? Select all that apply.

All individual code statements within each function

The database schema independently of all user interface components

All functions where user input is provided, tested with both correct and incorrect inputs

All system functions that are accessed through menus

Combinations of functions accessed through the same menu

Correct Answer

(1) All system functions that are accessed through menus

(2) Combinations of functions accessed through the same menu

(3) All functions where user input is provided, tested with both correct and incorrect inputs

Explanation

The system testing policy for interactive systems specifies: (1) all menu-accessible functions must be tested; (2) combinations of functions from the same menu must be tested (e.g., text formatting combinations); (3) all functions with user input must be tested with both correct and incorrect input. Statement-level coverage is a unit testing concern, not a system testing policy.
