Introduction to Quality Assurance: What Every Beginner Should Know

Quality Assurance (QA) is a critical component of software development, ensuring products meet specified requirements and deliver value to users. Whether you're just starting your QA career or transitioning from another field, understanding fundamental concepts is vital. This article provides you with a clear foundation in QA, practical insights, and actionable advice to kickstart your journey.

• Cost Reduction: Early bug detection significantly reduces the overall cost of fixing issues.
• User Satisfaction: Reliable, high-quality products increase customer satisfaction and loyalty.
• Reputation Management: QA helps maintain a company's credibility and market reputation by consistently delivering stable and functional software.

• Customer Focus: Always keep user needs and expectations at the forefront.
• Prevention Over Correction: Proactively identify issues rather than reactively fixing bugs.
• Continuous Improvement: Regularly refine processes and methodologies for better results.
• Clear Communication: Maintain transparent communication with stakeholders, developers, and project managers.

• Manual Testing: Testing software manually to discover bugs and usability issues.
• Automated Testing: Using automation tools and scripts to execute tests efficiently.
• Functional Testing: Validating software features against specified requirements.
• Non-functional Testing: Assessing software performance, usability, security, and reliability.

• Bug/Defect: An error or flaw that causes software to behave unexpectedly.
• Test Case: A set of steps and conditions used to verify specific software functionality.
• Test Plan: A document detailing the objectives, resources, and schedule for intended tests.
