ITPEC FE Subject A October 2024 — Question 38 of 60

Stub vs Driver in testing — driver calls the module under test; stub is called by it.

  • Driver — passes arguments and calls the module being tested (used in bottom-up testing)
  • Stub — replaces a lower-level module that the tested module depends on (used in top-down testing)

Why not others:
- (a) Reversed — describes a stub, not a driver

- (c) Reversed — a stub does not call the module under test; it is called by it

- (d) A stub simulates dependent module behavior, not display/print results

Key rule: Driver drives from above (calls down), Stub stands in from below (fakes a dependency).
