A test team is using a shared test environment. A critical defect requires an urgent fix that involves changing a configuration file used by multiple test suites. The change is small but could affect other tests. The test lead must decide how to proceed. What is the best approach?

Ask the developer to make the change directly in the production environment instead.

Perform a quick impact analysis, obtain approval from the test lead, apply the change, and inform all affected teams.

Reject the change because it could affect other tests.

Make the change immediately and document it after the fact to avoid delaying the fix.

What is defect removal efficiency (DRE) used to measure?

The percentage of defects removed before release compared to the total defects

The speed at which defects are fixed

The number of defects that are rejected as invalid

The number of defects found per test case

A test manager is analyzing defect metrics and finds that the average time to fix a defect is increasing, while the defect detection rate is stable. What is the most likely implication of this trend?

The testing process is becoming more effective at finding defects.

The software quality is improving.

The defect management process is working efficiently.

The defects being found are becoming more complex or the team's capacity to fix them is decreasing.

A project has a defect density of 5 defects per 1000 lines of code in module A and 2 defects per 1000 lines of code in module B. What can be inferred from this data?

Module A is likely to have more defects relative to its size than module B.

Module B has more total defects than module A.

Module A is more thoroughly tested than module B.

Module B is more complex than module A.
