Software Development Life Cycle

It is a process or procedure to develop a software or you can say it is a kind of methodology a developer is using to build a software. So as a software tester we also have to understand this process.

Different procedures/models are available to develop a software namely:-

  1. Waterfall Model
  2. Spiral Model
  3. V-Model / V & V Model ( Verification & Validation Model)
  4. Prototype Development Model
  5. Derived Model or Customized Model
  6. Hybrid Model
