Testing network configurations with free traffic generators

There are many ways to generate data streams, this article presents some commonly used methods during test automation. The commercial solutions are more expensive. However, there are a lot of cases where we can use non-commercial, free-of-charge solutions and tools to check things like predefined requirements, configurations, etc.

Page Object Model with Playwright and TypeScript

Page Object Model (POM) is a design pattern that plays a crucial role in maintaining a structured and organized approach in automated testing, particularly in the context of web application testing.

Network devices benchmarking methodology — RFC 2544 performance testing

Networking devices are complex and characterizing their performance is not easy. One must not judge performance based only on the number and type of ports. On the other hand, the performance figures that can be found in marketing materials may not be conclusive. Therefore, some while ago, the effort was made to create a unified benchmarking methodology to produce reliable, repeatable and comparable results. In this short article we’ll describe the basic performance metrics of networking devices and the methodology used to measure them.

Network Interface Card (NIC) Testing — the optimal environment setup

As we can see in Ethernet Alliance’s 2023 Roadmap, we can now use link speeds up to 400Gb/s. Speeds 800Gb/s and 1.6Tb/s are “in development” and 3.2Tb/s is marked as a “possible future speed” for the 2030s. Compared to 10Mb/s in the 1980s, now we have devices functioning 40,000 times faster! With such acceleration, Jules Verne’s “Around the World in Eighty Days” would be called “Around the World in 2.88 Minutes”. The goal you need to achieve during test environment preparation is that the tested network interface card (also called a NIC, network interface controller, or network adapter) will be a bottleneck in the hardware configuration.

The importance and benefits of unit testing

Ensuring code quality and reliability is critical in the modern software development world. One of the possible solutions to achieving this goal is unit testing. Unit testing involves breaking down software into smaller components or units and subjecting them to rigorous testing. It helps identify bugs and errors early on and provides benefits that significantly enhance the development process. In this article, we delve into the importance of unit testing and explore its various benefits to developers and businesses.

iPerf testing — overview and basic use case

iPerf is a versatile and powerful tool that has become essential for network administrators and IT professionals alike. Designed to measure the performance and throughput of a network, iPerf provides valuable insights into network bandwidth capacity, latency, and packet loss. By simulating real-world traffic conditions, iPerf enables users to assess network performance, identify bottlenecks, and optimize their infrastructure. In this article, we explore how iPerf works and delve into a practical use case to understand its effectiveness in network diagnostics and optimization.

Best practices for Python code quality — linters

When developing and maintaining software, code quality is of paramount importance. Being confident that code is readable and therefore easier to maintain and more efficient not only makes it easier for developers to work together, but also significantly reduces the likelihood of errors. One effective way to maintain high quality and at the same time ease of use is to use Python linter tools. These tools are helpful in ensuring Python code is clean, consistent and error-free, resulting in a streamlined development process and a better final product.

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.

Manual testing vs. automated testing — main differences

The need for rapid development and competitive time to market means companies are looking for time-saving solutions at every stage of development, including testing. This has resulted in the emergence of new tools that automate the testing process and make it more efficient. But will automated testing ever fully replace manual testing? Let’s take a look at both kinds of tests, when to use them, and their main differences. Let’s start with the original method of testing, the manual one. Before any product reaches the market, it needs to be thoroughly checked - whether it’s safe, functional, and easy to use.
