Software Testing Stages/Phases in SDLC

Software Testing Stages

 In general large scale companies are following fish model/Agile Model
To develop a quality software

But small and medium scale organisations are following V model to develop quality software

Testing Stages are common in all SDLC Models like Fish model, V model and Agile Model


§  Documents testing : In this stage business analyst can review BRS    In general BRS having “Customer Requirements”  so this document is called CRS/URS



§  When BRS was reviewed by BA corresponding SA can prepare SRS having Software Requirement with respect to  BRS 




From the above example BRS specifies
“What to develop?”
“SRS” specifies “How to develop?”
Corresponding SA can review SRS from completeness and correctness

When SRS document was base lined (reviewed)
Technical Architect can start design High level and low level


·       High level Design can define overall architecture of complete  software due to this reason ,HLD is also called as
Archeticterural design/system design











·       Low level Design is defining internal architecture of specific module
So one software consists of one high level design and multiple low level designs
