Software Development Life Cycle (SDLC) is a sequence of different activities performed during the software development process.
Software Testing Life Cycle (STLC) is a sequence of different activities performed during the software testing process.
Difference between SDLC and STLC:
|SDLC is mainly related to software development.||STLC is mainly related to software testing.|
|Besides development other phases like testing is also included.||It focuses only on testing the software.|
|SDLC involves total six phases or steps.||STLC involves only five phases or steps.|
|In SDLC, more number of members (developers) are required for the whole process.||In STLC, less number of members (testers) are needed.|
|In SDLC, development team makes the plans and designs.||In STLC, testing team makes the plans and designs.|
|Goal of SDLC is to complete successful development of software.||Goal of STLC is to complete successful testing of software.|
|It helps in developing good quality software.||It helps in making the software defects free.|
|SDLC phases are completed before the STLC phases.||STLC phases are performed after SDLC phases.|
