Question
Which SDLC model integrates testing at every phase of
development, ensuring defects are identified early?Solution
The V-Model, also known as the Verification and Validation model, integrates testing at every phase of development. For each development stage, a corresponding testing phase is planned, ensuring defects are detected early. This parallel approach minimizes rework and enhances product quality. The V-Model is especially useful for projects with well-defined requirements, where early detection of issues is critical. Each testing phase, such as unit testing, integration testing, and system testing, corresponds to a specific development stage, creating a "V" shape in the development timeline. Why Other Options Are Incorrect: 1. Waterfall Model: Testing is conducted after the development phase, delaying defect detection. 2. Agile Model: Incorporates iterative testing but does not align testing with each development stage. 3. Spiral Model: Focuses on iterative development with risk assessment but not integrated testing. 4. Incremental Model: Adds functionality incrementally but does not align testing phases with development.
