Difference between SDLC and STLC

Question

Accepted Answer

SDLC is the overall process of software development, while STLC is specifically focused on testing within that process.

SDLC (Software Development Life Cycle) includes all the phases of software development from planning to deployment.
STLC (Software Testing Life Cycle) is a subset of SDLC and focuses on testing activities like test planning, design, execution, and closure.
SDLC is more comprehensive and involves development activities like requirements gathering, design, coding, and maintenance.
STLC is more specific to testing and ensures that the software meets quality standards and requirements.
Example: In SDLC, developers write code based on requirements, while in STLC, testers verify that the code meets those requirements through testing.
