How are SDLC and STLC connected?

Question

Accepted Answer

SDLC and STLC are interconnected processes that ensure software quality throughout development and testing phases.

SDLC (Software Development Life Cycle) outlines the phases of software development, including planning, design, implementation, and maintenance.
STLC (Software Testing Life Cycle) focuses on the testing phases, ensuring that software meets quality standards before release.
Both cycles are interconnected; STLC activities are integrated into SDLC phases to ensure quality is maintained from the start.
For example, during the SDLC design phase, test planning in STLC can begin to identify test cases early.
In the implementation phase of SDLC, STLC conducts unit testing to catch defects as soon as code is developed.
