10 Which status commonly indicates that a bug has just been reported?

11 What usually happens after a developer marks a bug as fixed?

16 What is a common limitation of manual bug reporting?

17 What can an automated test system do when a test fails?

18 Which item can be attached automatically to a bug report after a test failure?

19 What is Bugzilla primarily used for?

20 What is a Bugzilla bug ID?

21 A tester reports that a checkout button sometimes fails but provides no environment details or reproduction steps. What action would most improve the likelihood that the bug is fixed promptly?

22 A developer closes a report because the stated behavior matches the current requirements. The tester believes the behavior still harms users. What is the most appropriate next step?

23 Which bug summary is most likely to help a development team understand and prioritize a defect quickly?

24 A web page fails only in one browser. Which test best isolates whether the browser is the relevant variable?

25 A test fails after a sequence of ten actions. What is the best technique for finding the smallest sequence that still triggers the failure?

26 A failure occurs intermittently during file uploads. Which information would be most useful for making the bug reproducible?

27 A spelling error appears on the home page, while a separate defect corrupts customer payment records but has a rarely used workaround. Which defect should generally receive the higher severity?

28 A minor visual defect affects a demonstration scheduled for an important customer tomorrow. How should it most reasonably be classified?

29 Which factor is most relevant when assigning the severity of a newly discovered bug?

30 A developer marks a defect as fixed. What should normally happen before the defect is closed?

31 During verification, a tester follows the original reproduction steps and observes the same failure. Which status transition is most appropriate?

32 A newly reported defect describes exactly the same failure and root condition as an existing open report. What is the most appropriate resolution for the new report?

33 A team wants to identify all unresolved critical defects assigned to the payment component for the next release. Which bug-tracking feature best supports this task?

34 Why should a bug-tracking system preserve the history of field and status changes?

35 A small team tracks bugs in a shared spreadsheet. Two testers edit the same row and one tester's update is lost. Which limitation of manual tracking does this demonstrate?

36 When reporting a bug manually by email, which practice best preserves consistent information for later tracking?

37 An automated UI test fails in a continuous-integration pipeline. Which set of attachments would provide the strongest diagnostic value in an automatically created bug report?

38 A flaky automated test creates a new defect after every intermittent failure. What is the best way to reduce duplicate reports while retaining evidence?

39 A Bugzilla user needs to find open defects in the authentication component assigned to a particular developer. Which feature should the user apply?

40 In Bugzilla, a tester wants to be informed when comments or status changes are added to a defect owned by another person. What should the tester typically do?

41 A developer closes a defect as "cannot reproduce" because the original report only states that a page sometimes freezes. Which additional evidence most directly increases the probability that the defect will be fixed?

42 A high-impact defect is reported one day before release, but the workaround is reliable and the fix would require changing a shared authentication component. What is the most defensible next action?

43 A failure occurs only when three feature flags are enabled. Disabling any one of them makes the failure disappear. Which isolation strategy is most useful initially?

44 A test fails intermittently after a timeout change. Re-running the same test produces different results, and timestamps show that a background job sometimes overlaps the assertion. What is the strongest next step?

45 A defect cannot be reproduced on the latest build, but it is reproducible on the customer's deployed version. Which comparison is most important before closing the report?

46 Which defect should generally receive the highest priority when prioritization considers user impact, exploitability, and available mitigation?

47 A defect affects only 0.1% of sessions, but those sessions corrupt financial records and cannot be recovered from backups. Which classification principle best applies?

48 A developer marks a defect as fixed, but the verification test fails on the target release candidate. What is the most accurate state transition?

49 Two reports describe the same underlying defect, but one includes a customer-specific data set and the other contains a broader minimal reproduction. How should the reports normally be managed?

50 A report is moved from resolved to closed immediately after a developer's commit, without verification. What process weakness does this reveal?

51 A team wants to measure whether its backlog is becoming healthier. Which metric is least misleading when interpreted with appropriate segmentation?

52 A tracking system allows any user to edit severity after triage, and reports frequently change from critical to minor without history. Which control most improves auditability?

53 An automated test creates a new issue for every failure, although the same assertion fails across many builds. Which tracking design best reduces duplicate noise while preserving regression visibility?

54 Which manual report is most actionable for a defect involving inconsistent currency totals?

55 A tester reports that a search result is missing but omits the query's whitespace, case, account permissions, and data state. Why is the report weak?

56 A tester discovers that a reported failure depends on confidential customer data. What is the best reporting practice?

57 A continuous integration job reports a failed test, but the failure is caused by an unavailable third-party service. What should an automated reporter include to avoid misclassifying it as a product defect?

58 An automated integration creates duplicate reports when a pipeline retries after a network timeout. Which mechanism most directly addresses this problem?

59 A test suite automatically files defects for transient UI timing failures. The backlog grows rapidly, even though most failures disappear on rerun. Which policy is most appropriate?

60 In Bugzilla, a defect is assigned to the wrong product and therefore does not appear in the responsible team's normal query. Which combination most directly restores routing and visibility?
