The Software Testing Life Cycle (STLC) is a systematic approach to testing software applications. It comprises distinct phases, including requirement analysis, test planning, test case development, test environment setup, test execution, and test cycle closure. STLC ensures thorough testing, defect identification, and delivery of high-quality software products.

1. SOFTWARE TESTING
LIFE CYCLE (STLC)
The Software Development Life Cycle (SDLC) involves
phases such as requirement analysis, design,
implementation, testing, deployment, and maintenance,
ensuring structured development and delivery of high-
quality software. Various methodologies like Waterfall,
Agile, Scrum, and DevOps are employed to manage and
iterate through these phases efficiently.

2. 1. Quality Assurance
• STLC ensures thorough testing coverage, defect identification, and enhanced
user satisfaction by systematically executing test cases.
2. Risk Mitigation
• STLC facilitates early risk identification, improved decision making, and
reduced business impact by providing insights into software quality and
stability.
3. Cost and Time Efficiency
• Integrating STLC into the development process optimizes the lifecycle,
accelerates time-to-market, and optimizes resource utilization, leading to
cost savings and improved project efficiency.

BEST PRACTICES FOR STLC

7. Software Testing Life Cycle (STLC) plays a pivotal role in ensuring the quality,
reliability, and success of software applications. By embracing STLC,
development teams can unlock a multitude of benefits, including enhanced
product quality, reduced risks, and improved resource efficiency. Embracing
STLC not only fosters a culture of quality assurance but also empowers teams
to deliver high-performing software that meets and exceeds user
expectations. As the landscape of software development continues to evolve,
exploring and adopting STLC methodologies can serve as a catalyst for
innovation, growth, and competitive advantage in today's dynamic market.
