Software Testing & Quality Assurance Exam Q&A (100+ Questions) | Agile, Black-Box, Metrics, Performance Testing | Software Engineering

This document provides 100+ comprehensive exam questions and answers for the course Software Testing and Quality Assurance, structured around the 2025/2026 academic year. It covers theoretical principles and practical techniques from lectures, making it a complete and reliable revision tool for both exams and certifications in the software quality field. The content begins by distinguishing quality assurance from quality control, then progresses into key frameworks like Total Quality Management (TQM) and the costs of quality (prevention, appraisal, failure). Students will benefit from detailed insights into defect classification, the journey from mistake to failure, and the phases where major defects are introduced (requirements, design, implementation, testing, and maintenance). The document explores static vs dynamic operations for defect detection, the structure and costs of inspections, walkthroughs, and reviews. It categorizes defects by type (e.g., data, functionality, human factors), class (missing, extra, wrong), and severity (major, minor). Black-box testing techniques are explained in depth, including: Equivalence Partitioning Boundary Value Analysis Decision Table Testing State Transition Testing Syntax and Cause-Effect Testing White-box testing concepts are also covered, focusing on: Control Flow Graphs Path, Statement, and Decision Coverage Condition and Path Testing Mutation Testing Additional sections cover: Regression vs Re-Testing Types of performance testing (load, stress, spike, endurance, configuration) SCRUM principles and the cost of defects over the development lifecycle Software metrics and the GQM paradigm (Goal-Question-Metric) Testing levels: Unit, Integration, System, Acceptance, and Installation Configuration Management fundamentals including change control, audits, versioning, and centralized vs distributed models This exam guide is ideal for: Undergraduate and postgraduate students in Software Engineering, Computer Science, and Information Technology Candidates preparing for ISTQB, CSTE, or other SQA/testing certifications Instructors and teaching assistants in need of ready-to-use Q&A for exam prep QA analysts and developers aiming to strengthen testing methodology knowledge Keywords: software testing, quality assurance, quality control, defect classification, walkthrough, inspection, reviews, TQM, cost of quality, equivalence partitioning, boundary value analysis, black-box testing, white-box testing, state transition, mutation testing, performance testing, regression testing, re-testing, SCRUM, software metrics, GQM, configuration management, unit testing, system testing, acceptance testing, integration testing, control flow graph, decision coverage, path testing, defect prevention, agile testing
