Question 1

Which element is the most important part of a good bug report?

Accepted Answer

Clear steps to reproduce, with expected vs actual result. Good bug report = title, environment, steps to reproduce, expected result, actual result, evidence (screenshot/video/logs), severity.

Question 2

What is the difference between severity and priority?

Accepted Answer

Severity = technical impact of the bug; priority = how urgently the business wants it fixed. Classic example to give in interviews: company logo misspelled on the homepage, trivial severity, very high priority.

Question 3

What is a smoke test?

Accepted Answer

A small, fast set of checks that verify the critical paths work before deeper testing. Smoke = shallow and wide, run first on every build. Regression = deeper re-testing of existing behavior after changes.

Question 4

A field accepts ages 18 to 65. Which set of test values applies boundary value analysis correctly?

Accepted Answer

17, 18, 65, 66. Boundary value analysis: test the minimum, the maximum, and one step outside each. Combine with equivalence partitioning (one value per class).

Question 5

What is exploratory testing?

Accepted Answer

Structured, simultaneous learning and testing of the app without pre-written step-by-step cases. Strong answer format: exploratory testing = charter ('explore checkout with invalid cards') + time box + notes on what was tried and found.

Question 6

The requirement says 'the report exports as PDF'. Verification vs validation, what is the difference?

Accepted Answer

Verification: did we build it as specified? Validation: does it actually serve the user's need?. Verification = against the spec. Validation = against the real need. Interviewers want the one-line version: build the thing right vs build the right thing.
