IKM - International Knowledge Measurement Software Quality Assurance Methodologies Questions and Answers

Question 1

A QA team receives a new build with a critical bug fix. Before proceeding with extensive regression testing, the team decides to run a quick set of high-level tests to ensure the fix works and that the build's core functionalities are stable. What is this type of testing called?

Accepted Answer

Smoke Testing

Answer

Smoke testing is a preliminary, non-exhaustive set of tests to ascertain that the most crucial functions of a program work, ensuring the build is stable enough for more rigorous testing. It covers the core functionalities end-to-end at a high level.

Question 2

Which of the following best describes the primary goal of regression testing in a software quality assurance process?

Accepted Answer

To ensure that recent code changes or bug fixes have not adversely affected existing features.

Answer

Regression testing is specifically designed to uncover new bugs in existing functionality after a change, such as a bug fix or feature addition. Its purpose is to ensure that the existing, previously tested software still performs correctly.

Question 3

In the V-Model of software development, which testing level is designed to directly validate the Architectural Design phase?

Accepted Answer

Integration Testing

Answer

The V-Model demonstrates the relationships between each development phase and its corresponding testing phase. Integration Testing, which verifies that different modules can communicate and work together, directly corresponds to the Architectural Design (or High-Level Design) phase.

Question 4

A development team follows a practice where they first write an automated test case that fails. They then write the minimum amount of application code required to make that test pass, and finally refactor the new code for quality. Which SQA methodology is being described?

Accepted Answer

Test-Driven Development (TDD)

Answer

This scenario describes the classic 'Red-Green-Refactor' cycle of Test-Driven Development (TDD). A failing test is written (Red), minimal code is written to pass the test (Green), and then the code is cleaned up (Refactor).

Question 5

A QA engineer is tasked with evaluating a system's ability to handle an increasing number of concurrent users up to and beyond its specified limits, with the specific goal of identifying the system's breaking point. What is this type of non-functional testing called?

Accepted Answer

Stress Testing

Answer

Stress testing is designed to determine the stability of a system by testing it beyond its normal operational capacity. The goal is to observe at what point the system fails and how it recovers. In contrast, load testing measures performance under expected normal and peak loads.
