V model - means the testing involvement starts from the design state itself & continues till system test.Phase             Testing Requirements - review design - reviewTR - TUTthen testing phases starts. So, like this testing makes a perfect V. so we call it V model.

"V" Model is one of the SDLC Methodologies.In this methodology Development and Testing takes place at the same time with the same kind of information in their hands.Typical "V" shows Development Phases on the Left hand side and Testing Phases on the Right hand side.Development Team follow "Do-Procedure" to achive the goals of the company and Testing Team follow "check-Procedure" to verify them.

Testing should do along with development process. That is what Spiral SDLC is talking about. In V model, testing and development phases are performing parallel. In that aspect Testing fits in V modelKavita Kharayat

Hi V-Model is a Testing Life Cycle Model which is entirely different from Software Development Life Cycle.V-Model is used for tester's where as SDLC we have developers and testers.SDLC models are 1. Waterfall model2.Prototype Model3. Spiral ModelTLC Models are1. Fish Model and2. V-ModelIn V-Model the strategy goes like this Gathering phase                                                            User Acceptance Testing.         Analysing phase                                     System Testing                  Design Phase             (HLD and LLD)                           Integration Testing                     Coding phase              Unit Testing                                            buildHere unit testing is done related to CodingIntegration testing is based on Design phaseSystem Testing is done related to Requirements (Analysing phase)User acceptance is done based on Gathering phase.ThankssameerQA Test Lead( Certified Tester)

The level of test is the primary focus of a system and derives from the way a software system is designed and built up. Conventionally this is known as the "V" model, which maps the types of test to each stage of development.

V model is a process model that helps in improving the quality of the software product by combining SDLC & STLC. In this model both SDLC & STLC works parallel. The left hand side of the V model contains SDLC in down-hill direction & the right hand side of the V Model contains STLC in up-hill direction.

V Model is a process where development & testing can do parallel. For every development phase there is a testing phase. Development phases are called as verifications & testing phases are called as validations. Here the verification means the software implements correctly or not & the validation means the software that has been built is traceable to customer requirements or not.

I think there are two ways to review this one is that as each set of deliverable is produced there is a validation process that goes with it

Therefore the Requirements deliverables are validated and the outcome should be an acceptance test plan and the finished application should be accepted based on those requirements.

As the design and development deliverables are finalized an integration of system test plan should be developed as an outcome of the validation of those deliverables and the application is accepted and validated based on the information from that level of deliverable
at a lower level program and module specifications are used as the basis for program or module level tests (white box) and unit level test plans are the result of those validation activities.

The validation activities that create the test plans occur shortly after the deliverable is created in an effort to catch defects or issues in the deliverable to take advantage of the cost of changes curve metric. The plans are executed in reverse order of their creations Program or unit tests executed first created last, integration plans created second and executed second, acceptance plans created first and executed last.

In all instances the plans should include test case definitions and details as the design and UI definitions become available.

V model : As the letter "V" says, left line of the "V" contains the developing phases while right line of the "V" contains all the testing phases.
For each level of a development phase there is an associated testing phase.
