Selenium is a well renowned automation testing framework used extensively for cross browser testing. The open source testing tool is a smart choice for companies offering software testing services for automation testing of different web applications across browsers such as Internet Explorer, Chrome, Firefox, and Microsoft Edge. Selenium offers extensive competition, compared to different test frameworks like HP Unified Functional …
Once upon a time, when dinosaurs roamed the earth, servers had to be built. A development team requested an environment for their code to run in, and a system administrator or infrastructure engineer plugged in a server and spent hours or days getting it ready to run code. Oh, and by the way, that was only one server of many …
Java agents are a special type of class which, by using the Java Instrumentation API, can intercept applications running on the JVM, modifying their bytecode. Java agents aren’t a new piece of technology. On the contrary, they’ve existed since Java 5. But even after all of this time, many developers still have misconceptions about this feature—and others don’t even know …
The widespread use of automation and the quest for increasingly shorter development cycles can be considered the hallmarks of the current era of software development. Practices such as Continuous Deployment and Continuous Integration, which were unimaginable not that long ago, nowadays are commonplace techniques that most software professionals take for granted. In this scenario, designing and maintaining a functional CI/CD …
You may have heard of aspect-oriented programming, or AOP, before. Or maybe you haven’t heard about it but have come across it through a Google-search rabbit hole. You probably do use Spring, however. So you’re probably curious how to apply this AOP to your Spring application. In this article, I’ll show you what AOP is and break down its key …
As companies evolve from a monolithic architecture to microservice architecture, some common challenges often surface that companies must address during the journey. In this post, we’ll discuss one of these challenges: observability and how to do it in AWS Fargate. A Little History Before Talking AWS Fargate Monitoring Twenty years ago, applications were different from what they are today. They …
When you spend a long time building an app or website just to have users complain about latency issues, it is not fun. You don’t know where the problem lies, nor do you know the environment in which it occurred. So it gets ignored, and performance issues keep lingering, like a haunting memory. This not only wreaks havoc on the …
Many things in programming sound like they should be easy, but are quite hard. Calculating elapsed time in Java is one of those. How hard could that be? As it turns out, it can be tricky. For starters, we have the fact that time itself is a tricky concept. For a quick example, remember that many places around the world …
One challenge for developers beginning a new project is choosing between monolithic and microservice architecture. According to Camunda research, 63% of enterprise level companies have taken steps to apply microservice architecture. Let’s take a closer look at the benefits and implementation of microservice architecture and why enterprise level companies, like Amazon, Netflix, and Uber, are choosing this architecture over traditional …
Today’s post is a detailed guide on how to send custom metrics to AWS CloudWatch monitoring using AWS Lambda. Starting from scratch, we’re going to finish up this post by leaving a serverless project running on Amazon Web Services (AWS). And do you want to hear the best part? Getting started will cost you less than you might spend on a …
People who are new to hosting web apps on IIS (Internet Information Services) sometimes struggle with the concept of application pools. What is an IIS application pool? What purpose does it serve? In this post, we’ll answer these questions—and more. We’ll begin by offering a brief introduction to IIS itself. If you’re already well acquainted with this piece of software, …
As exciting as it can be to write new features in your ASP.Net application, our users inevitably encounter failed requests. Do you know how to troubleshoot IIS or ASP.NET errors on your servers? It can be tempting to bag on your desk and problem your annoyance. However, Windows and ASP.NET provide several different logs where failed requests are logged. This …
.NET Profilers are a developer’s best friend when it comes to optimizing application performance. They are especially critical when doing low level CPU and memory optimizations. But did you know that there are three different types of profilers? Traditional .NET profilers that track process memory usage, time spent per line of code and frequency of method calls. Lightweight profilers or other …
Digitalization is sweeping across many industries, creating a huge need for innovation. This innovation forces companies to be more agile and deliver faster. However, increasing the speed of your development team doesn’t happen by magic. It’s a metric that isn’t easy to change. How can you adjust to this fast-paced digitalization? I want to introduce you to DevOps. DevOps helps …
Have you heard the saying “you can’t manage what you can’t measure?” The phrase is often attributed to management thinker Peter Drucker, and less often to other authors as well. It can also slightly vary in its wording, depending on the source. At the end of the day, the exact wording of the sayer and who said it first doesn’t …
Over the last decade, DevOps has become an important part of software engineering culture, influenced by the wide adoption of microservices, containers and cloud computing. A recent step in the evolution of cloud-based and microservice architecture is the serverless computing – a code execution model where the cloud provider takes total responsibility for the operating system and hardware management. The …
Imagine you’re driving a car, but there’s no windshield. You can’t see in front of you. On top of that, your car is full of friends looking out the side windows and yelling various things to you: “We should turn left!” “No, we should turn right!” “I’m pretty sure the next turn is in two miles.” In this scenario, how …
If you’ve been writing code for any reasonable amount of time, then it’s virtually impossible that you haven’t handled logging in any way, since it’s one of the most essential parts of modern, “real life” app development. If you’re a .NET developer, then you’ve probably used some of the many famous logging frameworks available for use at this platform. Today’s …
The software development life cycle (SDLC) started to become a formalized process for software development in the 1960s. That’s pretty much when software systems started to exist. With its loosely defined development phases, the SDLC has become a software development term that gets a lot of people talking. The SDLC, however, is more of an acronym packed with meaning than …
