The Software Testing Life Cycle (STLC) involves requirement analysis, test planning, test case development, test environment setup, test execution, and test closure to ensure software quality and functionality.
STLC focuses on testing phases: requirement analysis, test planning, test case development, test environment setup, test execution, and test cycle closure. SDLC encompasses the entire development process: requirement analysis, planning, design, implementation, testing, deployment, and maintenance.
Software testing ensures that software meets quality standards, identifies defects early, reduces risks, enhances user satisfaction, and ensures functionality, security, and compliance with requirements and standards.
STLC focuses on testing activities to ensure software quality, while SDLC covers the entire development process, including planning, designing, coding, testing, deployment, and maintenance.
