Understanding the Defect Life Cycle in Software Testing

Every software application has bugs, but how a development team handles them determines the success of the project. Understanding how a defect travels from discovery to resolution is a foundational skill for any aspiring software tester, QA analyst, or developer. This text-based course guides you through the entire defect life cycle, equipping you with the terminology and processes used by professional engineering teams. You will learn how to identify, document, and track bugs systematically, ensuring clear communication across your team. What you'll learn: Understand the core terminology and foundational phases of the defect life cycle; Document clear, actionable bug reports that developers can easily reproduce; Classify defects accurately using industry-standard severity and priority levels; Track bugs through states like New, Assigned, Resolved, and Closed; Integrate bug tracking into modern Agile workflows and collaborative team environments; Practice identifying common pitfalls in defect communication through written scenarios. You will start with the basic definitions of errors, defects, and failures before exploring each stage of the life cycle step-by-step. The material then covers practical reporting techniques and how defect tracking fits into modern software development workflows. This course is designed for absolute beginners in software testing, quality assurance, or project management, with no prior technical experience required.
