Methodologies in Software testing

The field of software testing is ever expanding and with the advent of modern technology and increasing usage of IoT, software testing for various applications has become an absolute necessity. It should be noted that a typical software development life cycle (SDLC) comprises different software development processes.

It is important to select a proper model or methodology, depending on the type of software that is being tested. Here is a list of software testing methods:

Waterfall model: It is one of the commonest methodologies used for software testing. Owing to its success rate, it is also very popular among testers. It is a sequential process that flows downwards, in phases, just like a waterfall. This waterfall model is further separated into the following phases:

  • Requirement gathering and analysis phase
  • Software design
  • Implementation and testing
  • Maintenance

This model has to be operated flawlessly since one phase depends on the previous one. Therefore, it is important to first chalk out a list of objectives before embarking on the waterfall process.

V model: It is considered a best practice to introduce testing in the early phase of SDLC to get rid of initial loopholes. Before the actual software testing begins, the testing team has to make a detailed plan for preparing the testing scenario. This includes Test Strategy, Test Planning, Creation of Test cases and Test Scripts. These stages need to be executed parallel with the development activity that helps to get the test deliverables on time.

Agile Model: It is also a type of incremental model where the software is developed in incremental, rapid cycles. This results in small incremental releases with each release building on the previous operation. This testing is done from a customer perspective. The testing starts as early as the coding stage. This is done by using automated acceptance testing to minimize the amount of manual labor. In this process, the entire team is involved. Both the developers and the testers engage themselves in testing at the earliest possible stage to avoid any issues down the lane.

Spiral Model: This testing methodology is a combination of the waterfall model and iterative model. Each phase in the spiral model begins with a design goal and ends up with the client reviewing the progress. In this process, the development team in Spiral-SDLC model starts with a small set of requirement and goes through each development phase for those set of requirements. Functionality is added by the software engineering team for any additional requirement in every increasing spiral until the application is ready for the production phase. 

Rapid Application Development (RAD): The RAD model allows clients to try a particular application before buying. The idea behind developing this model is the fact that end users can be the best critiques rather than following documented protocols. In fact, RAD-models have resulted in a lower level of rejection when the application is placed in the production line.

Rational Unified Process (RUP): This is an object-oriented and web-enabled program development methodology. This methodology also provides guidelines, templates and examples for all aspects and stages of program development. RUP is also known to combine various processes of development within a unifying framework.
