STLC (Software Testing Life Cycle) Diagram Overview

This **STLC (Software Testing Life Cycle) Diagram** offers a clear and structured visual of the end-to-end testing process used in software development. The life cycle is divided into six critical phases: Requirement Analysis, Test Planning, Test Case Development, Test Environment Setup, Test Execution, and Test Closure. These phases guide QA teams in planning, designing, running, and finalizing test activities to ensure that software meets quality expectations. Moreover, the circular flow of the diagram emphasizes continuity and iteration, making it suitable for both Agile and Waterfall projects. Each stage plays a vital role in reducing defects, improving reliability, and validating that the product functions as intended. Therefore, understanding and applying the STLC process is essential for every tester, QA analyst, and software quality professional.

Key Features of the STLC Diagram

• Requirement Analysis: Understand what needs to be tested by reviewing documentation.
• Test Planning: Define strategy, scope, resources, and schedule for testing activities.
• Test Case Development: Write test cases and prepare test data.
• Test Environment Setup: Configure the software and hardware for testing.
• Test Execution: Run test cases and log defects.
• Test Closure: Finalize reporting, clean environments, and assess quality metrics.

What’s Included with the STLC Diagram

• Color-coded circular chart showing all six STLC phases in logical sequence.
• Concise labeling for easy reference in meetings, training, or documentation.
