Waterfall Model: It includes all phases of SDLC but the drawback is once requirement made freezed it cannot be changed.
Waterfall Model the tester role will take place only in the test phase
Waterfall madel is a fixed process u can't make any changes in the requirement or in any phase
waterfall model used only the requirements are fixed
V-Model: In this model all phases will be done correspondingly development and testing.
V-Model role will take place in the requirement phase itself
V-Model u can make any changes in the requirements
V-model is the simultaneous process but it is not in case of water fall model
V-model can be used for the any type of requirement(Uncertain requirement)
