Spiral STLC

 

1. Spiral Model:

   • The Spiral Model is a software development methodology that combines the iterative development process model with elements of the waterfall model.
   • It is particularly well-suited for large, complex projects with changing requirements.
   • The development process in the Spiral Model consists of a series of iterations called spirals, each representing a phase in the development process.

   The typical phases in a Spiral Model include:

   • Planning: Define the objectives, alternatives, and constraints of the project.
   • Risk Analysis: Evaluate potential risks and develop strategies to manage them.
   • Engineering: Develop, test, and verify the product based on the information gathered in the planning and risk analysis phases.
   • Evaluation: Review the results of the iteration and plan the next iteration.

2. Software Testing Life Cycle (STLC):

   • STLC is a sequence of activities carried out by the testing team to ensure the quality of the software or application.
   • It involves a systematic and planned approach to performing testing activities at each phase of the software development life cycle (SDLC).
   • The STLC process typically includes phases such as requirements analysis, test planning, test design, test execution, defect reporting, and test closure.

   The general phases in STLC may include:

   • Requirement Analysis: Understand and analyze the requirements to identify testable elements.
   • Test Planning: Plan the testing activities, including scope, resources, schedule, and test strategy.
   • Test Design: Create test cases and test scripts based on the requirements and design specifications.
   • Test Execution: Execute the test cases and report defects.
   • Defect Reporting: Log and track defects found during testing.
   • Test Closure: Evaluate the testing process, summarize results, and prepare closure reports.
