Best Testing and Software QA Methodologies + Checklist
2 min readJul 24, 2020
Software Testing Methodology is defined as strategies and testing types used to certify that the application under test meets client expectations. Test Methodologies include functional and non-functional testing to validate the AUT. Each testing methodology has a defined test objective, test strategy, and deliverables.
Testing models in SDLC:
- Waterfall Model. Waterfall model is the basic life cycle model. This model represents multiple stages or processes in a sequential manner that flows progressively downward.This approach is useful when requirements are well known, technology is understood and the resources with required expertise are available.
- V Model. V Model is an extension of Waterfall Model where the process execution takes place in a sequential style in V-Shape and is also known as Verification and Validation Model. In this approach, there exists a directly associated testing phase in every single phase of the development cycle. It has been proven beneficial and cost-efficient than the waterfall model as the testing is performed at each development phase rather than at the end of the development cycle.
- Agile Model. Agile Model shows an iterative and incremental approach. This approach breaks the product into small incremental units to provide iterations. Then each iteration involves steps like Planning, Requirement Analysis, Design, Coding, Unit Testing, Acceptance Testing etc.This approach also allows continuous interaction with the customer for their feedback and corrections in the requirements at regular intervals.
- Spiral Model. The spiral model incorporates iterative development approach along with the systematic approach of the waterfall model. It is similar to the incremental model and emphasis on Risk Analysis.
- RAD Model. Rapid Application Development(RAD) is a type of incremental model. In this approach, components are developed in parallel.This is a rapid approach and it can give a fast product to the customer to provide feedback.
