From start to finish: how to write a successful testing plan

Every stage of the software development lifecycle is equally important. However, if there is one part of development that has the biggest impact on the customer experience, it is probably testing. Missed bugs that turn up in the production environment make the worst impression on end users. And if you miss critical errors, the application can stop working at the most inopportune time which might cost your users, and your own business, a lot of money. Thorough software testing can prevent all this from happening.

What does CUPS mean in networks and what are its benefits

CUPS stands for Control and User Plane Separation. This is an architectural concept which says that for a given network solution, the Control Plane (CP) and User Plane (UP) functions are different entities. To read more on what Management, Control and User Planes (a.k.a Data Plane, or DP) are see Management vs. Control vs. Data Planes in a Network Device. But what does it mean in practice and where is the CUPS model implemented? What benefits does it bring compared to a combined model? The first thing that comes to mind when discussing CUPS is a mobile network or, more precisely, a mobile packet core.

What is cloud-native architecture — everything you need to know

Gone are the days when most IT companies had their own physical data centers. On-premises infrastructure is no longer a prerequisite for running a successful IT business. Cloud data storage and hosting has become so routine you barely even give it a thought. More often than not, customers expect your app to be hosted in the cloud because they associate it with less downtime, speedy work and reliability. However, when considering cloud infrastructure, there is a big difference between cloud-native and cloud-enabled applications.

What is test-driven development? Meaning, tests, and benefits

Do you want to deliver software faster and of better quality? Sure, everyone wants to. We know a methodology that will help you achieve that goal. The method is test-driven development (TDD), focusing on testing the first approach. In this article, you’ll learn what test-driven development is, its process, and also some pros and cons to give you a full understanding of TDD. Test-driven development concentrates on building unit test cases as a first step of coding new feature functions. In this iterative approach, you mix the traditional order of unit tests, refactoring, and programming.

Why is Rust programming language so popular?

Rust was created to ensure high performance similar to that offered by C and C++,but with emphasis on code safety, the lack of which is the Achilles heel of these two languages. However, Rust has more than just memory safety on its side. High performance while processing large amounts of data, support for concurrent programming, and this together with an effective compiler are other reasons why well-known software heavyweights now use this programming language. Firefox, Dropbox, Cloudflare, and many other companies from startups to large corporations use Rust in production.

Git commands with examples. A guide for developers

There are many ways to use Git repositories. You can install a plugin in your IDE, you can use Web UI or you can install a dedicated application only for working with Git. But it is a good idea to become friends with the Git command line tool. It is the most flexible tool that allows you to do all the things you can do with the above-mentioned tools and even more! In this blog post I will show you Git commands that help you to start working with Git command line tools and eventually become best of friends.

7 benefits of DevOps that will impact your business

In the traditional software development life cycle, there were separate teams dedicated to fulfilling specific tasks, like coding, testing, and deploying the final build in the production environment. These teams’ priorities often clashed with each other. Developers wanted to finish writing the code as fast as possible, so that the customers could access new features. However, the IT operations team, responsible for running the production site, was primarily focused on implementing the new changes safely and responsibly, which could be quite time-consuming.

The power of UX benchmarking in design and development

The market success of your software product depends on the user experience. Excellent user experience means higher user satisfaction, higher retention, increased customer loyalty, and steady income. To ensure a good user experience for your product, consider using UX benchmarking as one of your metrics. In this article, we will mostly focus on UX benchmarking and its key issues. UX benchmarking is a process where with the help of key metrics, you can assess your own product or compare it with competitor products.

Top 7 code coverage tools for Java

It is not a secret that writing code can sometimes take less time than making sure it works correctly. Running tests is crucial to guarantee the new build of your software has a successful release. Automating this task can save a lot of time for your developers and reduce time to market. But how can you be sure the tests you run are efficient enough? It is logical to strive to test as much of your code and as thoroughly as possible. That is why, for example, unit testing is used; it allows testing of smaller, logically isolated pieces of code like a property or a function.

We've previously explained how VPP processes packets in vectors as opposed to processing each packet end to end. But how is this processing spread across CPU cores? How exactly is a vector of packets structured?
