There are many development and testing models. choosing the right model for development and testing is very important. The wrong choice of a model could complicate the project, cause delays and sometimes even cancellation. the most popular model is the "Agile Methodology". the most older is the waterfall model.
Waterfall model /Sequential model
In this model, each stage follows on from the previous one.
The transition from stage to stage is done by filling out many templates.
Very slow to perform. From a testing point of view, it is simply too little, too late. The tester begins its work only when the code has been written.

V model
Verification and validation model. It highlights the fact that the testing is just as important as the software development itself. Writing software and testing in parallel.
Each phase completed before the next phase begins. in this model the first, we create a system test plane and only after that we start the process of development.

Agile model
This results in small incremental releases with each release building on previous functionality. each version passed inspection ensure software quality.
There is a number of models that are less popular:
Spiral model
RAD model
Iterative model
Incremental model
Prototype model
