The role of the V-model in software testing
The V-model is a modern version of the traditional waterfall model. It plays an important role when it comes to software testing. In this article, we raise the importance of the V-model and will take a closer look at it. Indeed, a good knowledge of software testing methods - of which the V-model is obviously one, is very important if you are a software tester. It will enable you to plan and execute tests properly and effectively to improve the quality of your software.
What is the V-model?
The V-model, an acronym for Verification and Validation Model, is an important software development model that is itself a more modern version of the waterfall model. The model was developed to overcome the shortcomings of the traditional waterfall model.
Linear testing and development
The V-model is in itself a linear process but differs from the waterfall process where the V-model has a concurrent testing procedure for each corresponding development phase. In itself, this means that there is a test phase for each development phase that is performed after the completion of each step of the development.
The V-model is designed to support the process of understanding, designing and coding software using a well-planned and tailored test procedure. The V-model therefore allows you to notice, identify and correct any defects or errors very early on. That way, you can easily and quickly increase the quality and reliability of your final product.
Characteristics of the V-model
Now that we know what the V-model is, we will also briefly list the characteristics of the V-model for you.
Phase-specific testing
A first characteristic of the V-model is that each development phase is immediately followed by a test phase. Indeed, this approach ensures that the testing process is very thorough. This way, not a single error is overlooked.
Early error detection
A second feature and immediately a big advantage of the V-model is that you can detect errors very early in the development process. You carry out development and testing activities almost at the same time, which means you can always easily jump back to the development phase after a failed test. This way of working not only increases your productivity but will also greatly enhance the quality of the software.
Clear structure
In addition, the V-model offers a very clear and, above all, logical structure. This therefore helps you plan and execute your software testing projects efficiently.
Improved communication
In conclusion, the V-model can also provide improved communication between developers and testers. This, in turn, can enhance understanding and especially collaboration within cross-functional teams. This is because there is a clear link between the phases and because developers can easily and quickly switch between the testing phase and the corresponding development phase.
Why is it important for software testers to understand the V-model?
As a software tester, it is of course of enormous importance that you know and understand the different testing models. That way, you can successfully carry out tests and make the necessary adjustments efficiently. Here, the V-model enables you to structure testing and gives you a systematic approach to testing that runs parallel to development.
Mastery of different software tests
If you have a good knowledge of a large number of different tests such as unit tests, integration tests, functional tests and end-to-end tests, you can work flexibly. This is because you can run these tests with ease on small, individual parts of the software - think unit testing, for example, or even testing the entire application as in end-to-end testing. By having a good knowledge of these types of tests, you will know perfectly which tests to apply to your project when and how.
