RAD (Rapid Application Development) STLC

 RAD (Rapid Application Development) and STLC (Software Testing Life Cycle) are two distinct concepts in the software development process. Let me provide you with an overview of both:

1. Rapid Application Development (RAD):

   • Definition: RAD is a software development methodology that prioritizes quick development and iteration. It focuses on rapid prototyping and feedback over strict planning and testing.
   • Key Characteristics:
     • Iterative Development: RAD involves iterative development cycles, where a prototype is quickly built, reviewed, and refined.
     • User Feedback: User feedback is crucial throughout the development process to ensure that the system meets the users' needs.
     • Incremental Changes: The system is built incrementally, and changes can be made easily based on user feedback and evolving requirements.
     • Time-Boxed: RAD projects are time-boxed, with fixed deadlines for each iteration.

2. Software Testing Life Cycle (STLC):

   • Definition: STLC is a set of processes or phases that guide the testing team to test the software. It encompasses activities from test planning to test closure.
   • Key Phases:
     • Requirement Analysis: Understanding and analyzing the requirements to create a comprehensive test plan.
     • Test Planning: Creating a detailed test plan that outlines the testing approach, resources, schedule, and deliverables.
     • Test Design: Designing test cases and test scripts based on the requirements and design specifications.
     • Test Environment Setup: Preparing the testing environment with the necessary hardware, software, and test data.
     • Test Execution: Executing the test cases and reporting defects if any are found.
     • Defect Reporting and Tracking: Documenting and tracking defects, communicating with the development team for resolution.
     • Test Closure: Assessing the testing process, creating a test summary report, and closing the testing phase.

While RAD and STLC serve different purposes, they can be integrated. In RAD, testing activities might be conducted iteratively after each prototype is developed, allowing for rapid feedback and refinement.
