In software development, defects are flaws or issues that can affect the performance of an application. These defects can include functional, performance, usability, and compatibility issues. Identifying, classifying, and managing defects is crucial for ensuring software quality and enhancing the user experience. Key concepts in defect management include:

• Defects can impact the performance of a software application.
• Common types of defects are functional, performance, usability, and compatibility issues.
• Effective defect reporting and tracking are essential for maintaining quality and communication in the development process.

Defect reporting involves documenting issues found during testing, while defect tracking is the process of managing and resolving reported defects. Best practices in defect reporting and tracking include clear descriptions, defect prioritization, and continuous tracking until resolution, improving QA efficiency. Key lesson concepts include:

• Documenting issues found during testing is part of defect reporting.
• Defect tracking entails monitoring, managing, and resolving reported defects.
• Best practices include providing clear descriptions, prioritizing based on severity, and tracking until resolution.

Another vital part of software testing is defect resolution, involving the identification and fixing of defects to enhance software quality. The defect resolution process includes steps like defect identification, logging, prioritization, fixing, retesting, and closure, with an emphasis on effective communication. Following this structured approach can enhance the testing process and deliver a high-quality product. Key points in the defect resolution process are:

• Accurate identification and logging of defects.
• Assigning priority levels based on impact.
• Clear communication among team members.
• Prompt defect fixing and software retesting.
• Closure of defects after verification and validation.
