Software testing Models and their usage

Software Testing is an art. And to learn this art, it takes years and expertise plus training. There are a lot of types, methods, that testers and Software Testing leads use. Industry best practices are always useful as there aren’t defined guidelines to have the best results. Once the idea is final the next step is to assess how well it can work. 

Here is a list of methods used for software testing:


As the name suggests, DevOps is a combination of Development and Operations which is a cultural shift to bridge the gap between development teams as well as operations teams. DevOps works like a set of practices that automate the processes between development and testing teams, for the purpose of having good quality software in less time. DevOps is a continuous lifecycle that is good to work in a collaborative environment.


Known to be the first model in processes, Waterfall, as the name suggests, is a method where stages or phases of development or SDLC do not collide. Having a waterfall model works best if there is departmentalization and control. Its development is shifting from the concept to design ideas, coding, testing, and then maintenance. A drawback is that in the waterfall model, as an inherent law, the phases cannot be altered. That is why it is seen as an unviable source now and cannot be used for big projects.


In Agile methodology, the SDLC becomes iterative. The project is divided into small builds and then development and testing teams work on those builds to make small increments. Instead of spending time on huge projects, it is viable to work on small projects and then form a bigger application. Having small builds not only saves time, but also can help with changing requirements from the clients and they have a better understanding of how a project is going to be like.


V-model is the model which lets people easily manage their SDLC. This means that like the Waterfall model, it is something that runs processes in parallel. The development phase and testing phase are run in parallel and the result is a tested phase. For each development phase, there is a parallel testing phase and that is why it is known as the V-model. You can easily test the coding that is created and has the testing completed for it. The left side of the V is known as the verification and the other side as validation.

These are some of the most prominent models and methods that are used in the everyday life of a developer and tester. For the purpose of delivering software better and in a fast manner. Regardless of the need, it is a fact that some people are more inclined to develop software without worry. One can easily choose a model that suits their need. Clients keep changing their requirements and that is one of the main concerns that hinder time-to-market. These models are shaped to better just that fact. Software testing leads often face the problem of keeping track of changes to the code and have to keep using old methods. This is why using new methods with latest tools can be beneficial in the long run. For big projects or small projects choosing the right models is key as software testing leads that are not experienced face this dilemma. A Lot of the pain points are resolved including the ones mentioned before and it can work wonders with client’s requirements as well, and you can read about more here on Software Testing Lead. Being able to have good quality software without a worry is a blessing that can be useful for testers and developer’s careers.
