Question 1

What is the purpose of a Requirements Traceability Matrix (RTM) in QA?

Accepted Answer

To map requirements to corresponding test cases ensuring full coverage

Answer

An RTM maps each business or system requirement to one or more test cases, ensuring every requirement is tested and no coverage gaps exist.

Question 2

Which testing level focuses on verifying individual components or modules in isolation?

Accepted Answer

Unit testing

Answer

Unit testing verifies the smallest testable parts of an application (functions, methods, classes) in isolation from other components.

Question 3

A QA process improvement model that defines five maturity levels for software processes is:

Accepted Answer

Capability Maturity Model Integration (CMMI)

Answer

CMMI defines five process maturity levels—Initial, Managed, Defined, Quantitatively Managed, and Optimizing—to guide process improvement.

Question 4

When a defect is found in production that was not caught during QA, the post-mortem analysis should primarily focus on:

Accepted Answer

Identifying process gaps that allowed the defect to escape

Answer

Post-mortem analysis aims to identify systemic process weaknesses that permitted defect escape, enabling improvements to prevent recurrence.

Question 5

Equivalence partitioning is a black-box testing technique that:

Accepted Answer

Divides input data into valid and invalid partitions to reduce test cases

Answer

Equivalence partitioning groups inputs into partitions where all values in a partition are expected to be treated the same, reducing the number of test cases while maintaining coverage.
