ITPEC FE Morning October 2023 — Question 52 of 80
Bug Convergence Curve — identify the graph showing quality stabilization during testing.
A cumulative bug curve that flattens into a plateau (S-shape) indicates quality is becoming stable:
- •Early phase: few bugs found (testers ramping up)
- •Middle phase: bugs discovered at high rate
- •Late phase: curve flattens — most bugs already found
Why not others:
- (a) — curve decreases, which is impossible for a cumulative count
- (b) — exponential growth means bugs keep accelerating — no stabilization
- (c) — linear growth means constant bug discovery rate — testing not converging
Key rule: A flattening cumulative bug curve (S-curve) = quality stabilization. If the curve never flattens, testing is not complete.
