ITPEC FE Morning October 2020 Question 49
ITPEC FE Morning October 2020 — Question 49 of 80
Bug Curve Analysis — interpret a cumulative bug count graph.
The graph shows cumulative bugs reaching the target value at test item X, but the curve is still rising steeply (no plateau).
What this means:
- The curve has not flattened → bugs are still being found at a high rate
- Reaching the target number does NOT mean testing is complete
- A large number of bugs likely remain undiscovered internally
Why not others:
- (b) Desk-checking/simulation done well — not supported; a well-prepared product would show fewer early bugs
- (c) Low probability of bugs after shipping — opposite is true; the steep curve means many bugs remain
- (d) Testing completed successfully — the curve shape shows testing should continue
Key rule: A healthy bug curve forms an S-shape (plateau = diminishing returns). A curve still rising steeply at the target means the product likely has many hidden defects.
