Verification and validation has existed for a while now, this is good for us because people have created many tools to make our jobs way easier. Testing nowadays is much easier and less exhausting than before and I will tell you of some of the most popular tools used for verification and validation. These tools each have their purpose and beware, they are not the only options out there, I will simply talk about the ones I’m most familiar with.
First, I would like to talk about git. Git a tool used for version control. If you are unfamiliar with this term, version control is a system used to record changes to a file or set of files over time. Git is probably the most popular tool used in V&V because of its usefulness when doing any kind of project. If you ever need to go back to some specific version of your files, you can. Let’s say you accidentally mess up something in your code by accident, with git you can simply go back to the last version where your code worked and not lose all your progress. It also allows people to work simultaneously on one project, letting you put everything together once the separate tasks are done. And if any conflicts are detected, it helps you fix them to ensure that the project works properly. There are other tools that can be used for version control but I would be lying if I said I’ve used them. Some of the most popular ones I found where Mercurial, CVS, and SVN, among others. From my experience, this is an essential tool and taking the time to learn how to use it properly is extremely worth the time, as it will make your life easier and your projects, in a way, quicker to manage.
From what I understand, it is harder to talk about only one testing tool since there are many out there used for very different purposes. We have test management tools, test execution tools, test data preparation tools, and the list goes on. In your projects, you will be required to use several different tools depending on what you want to accomplish. In most cases you are responsible for creating the test cases, these tools are meant to help you have a controlled place with all your tests on a particular part of the project and they can also help you automatize your tests. This is especially useful, it saves you time and once the test are done you know your code will properly do its job, that is if the tests were written correctly of course. Some testing tools can also be used while you are writing your code, rather than when you’re done. A very popular tool and one that I’ve used before is Postman. Postman helps you test your API to make sure that your endpoints are working properly. As I stated before, you must identify the parts of your project that need to be tested before you can decide which tools are required. Fortunately for us, there are tools for any kind of process imaginable when developing software, so it should only be a matter of investigating which appeals the most to your needs.
The last kind of tools I wanted to talk about were tools for process administration of V&V. The only problem is that I’ve never really had much experience with any tools of this sort, at least not that I’m aware of. What I know is that these tools, unlike the other tools that focus on a specific part of your projects functionality, are meant to help you in the process of validating and verifying your project.
Whatever your project may be and its purpose, you will always benefit from using tools to help you verify and validate its functionality. No matter which technologies you use, you should always look for a way in which you can prove that what you did is working as intended, otherwise there might be more problems in the future. Releasing code that you know works, even if it takes more time, is always better than releasing something that you didn’t fully test and having to fix it later.
