Question 1

Which software testing technique derives test cases by identifying equivalence classes of input data that the program treats the same way?

Accepted Answer

Equivalence partitioning

Answer

Equivalence partitioning divides input data into classes where the program behaves identically, reducing the number of test cases needed while maintaining coverage.

Question 2

In software quality management, what is the primary purpose of a Software Quality Assurance (SQA) audit?

Accepted Answer

To verify that software development processes comply with defined plans and standards

Answer

SQA audits verify process compliance against defined plans, standards, and procedures rather than evaluating the product itself.

Question 3

Which metric measures the number of defects found after software release compared to those found during testing?

Accepted Answer

Defect removal efficiency (DRE)

Answer

Defect Removal Efficiency (DRE) = defects found before release / (defects before release + defects after release), measuring how effectively testing caught defects.

Question 4

According to IEEE standards, what distinguishes a 'fault' from a 'failure' in software quality terminology?

Accepted Answer

A fault is a defect in the code; a failure is the manifestation of that defect during execution

Answer

IEEE defines a fault as a static defect in the code, while a failure is the externally observable incorrect behavior that results when a fault is executed.

Question 5

What is the main goal of software configuration management (SCM)?

Accepted Answer

To identify, control, and track changes to software work products throughout their lifecycle

Answer

SCM establishes and maintains the integrity of products by identifying configuration items, controlling changes, recording status, and auditing configurations.
