TS Test Execution & Data Collection 4

Question 1

Which of the following best describes 'confirmation testing' (re-testing)?

Accepted Answer

Executing tests that previously failed after a defect fix

Answer

Confirmation testing (re-testing) reruns tests that previously failed to confirm that a specific defect has been successfully fixed.

Question 2

A tester collects data on the number of defects found per phase (requirements, design, coding, testing). This is used to calculate which metric?

Accepted Answer

Defect removal efficiency (DRE)

Answer

Defect Removal Efficiency (DRE) measures the percentage of defects found before release versus all defects (pre-release + post-release), using phase-based defect data.

Question 3

During test execution, a critical defect is found that blocks all further testing. What is the correct classification?

Accepted Answer

Blocker defect

Answer

A blocker (or showstopper) defect prevents all or significant test execution from continuing until it is resolved.

Question 4

Which of the following is a primary benefit of automated test execution over manual test execution?

Accepted Answer

Automated tests can be run repeatedly without increased effort

Answer

Automated tests can be re-executed as many times as needed with consistent effort, making them ideal for regression testing.

Question 5

A test team tracks 'defect leakage' after a release. What does defect leakage specifically measure?

Accepted Answer

Defects found in production that were not caught during testing

Answer

Defect leakage measures the number of defects that escaped testing and were found by users in production.
