Explain the difference between an SDLC and STLC?

  • STLC (Software testing Life cycle ) is part of SDLC (Software development life cycle).
  • STLC deals with validation and verification of the software, where as SDLC deals with development/coding of the software
  • STLC is limited to the testing phase where quality of software or product ensures. SDLC has vast and vital role in complete development of a software or product.
  • However, STLC is a very important phase of SDLC and the final product or the software cannot be released without passing through the STLC process.
  • STLC is also a part of the post-release/ update cycle, the maintenance phase of SDLC where known defects get fixed or a new functionality is added to the software.
