Which QA activity is best described as a structured walkthrough led by the author of a work product?

Question 3

What does the 'shift-left' approach in QA primarily advocate?

Accepted Answer

Moving testing activities earlier in the development lifecycle

Answer

Shift-left means introducing testing and quality activities earlier in the SDLC to detect defects sooner and reduce cost.

Question 4

Which metric measures the percentage of requirements that have at least one corresponding test case?

Accepted Answer

Requirements traceability coverage

Answer

Requirements traceability coverage tracks how many requirements are linked to test cases, ensuring all requirements are tested.

Question 5

A QA team notices the same defect type recurring across multiple releases. What is the MOST appropriate next step?

Perform a process improvement analysis to address the root cause

Answer

Recurring defects indicate a systemic process issue that requires root cause analysis and process improvement, not just more testing.
