What is the software testing life cycle (STLC)?

STLC (Software Testing Life Cycle) is a sequence of phases performed during software testing to ensure product quality. It is a structured approach that guarantees testing is conducted systematically and effectively.

Main stages of STLC:

• Requirements Analysis: Studying functional and non-functional requirements to understand the testing scope.
• Test Planning: Defining testing strategy, objectives, resources, timelines, and effort estimation.
• Test Case Development: Creating detailed test cases based on analyzed requirements.
• Test Environment Setup: Preparing the necessary environment (hardware, software, data) for testing.
• Test Execution: Running test cases, recording results, and identifying defects.
• Test Cycle Closure: Preparing reports, analyzing results, closing defects, and summarizing.

# Example of testing life cycle stages
stlc_stages = [
    "Requirement Analysis",
    "Test Planning",
    "Test Case Development",
    "Test Environment Setup",
    "Test Execution",
    "Test Cycle Closure"
]

# Output stages

    print(f"- {stage}")

STLC helps ensure that testing is comprehensive and effective, which in turn leads to a higher quality software product.
