Modern-day applications aim to cover a wide range of users’ needs in a flexible and scalable manner. The software development landscape is moving at a fast pace, and the competition is so fierce that a business simply can’t afford to offer a low-quality product. Thorough testing of both functional and non-functional aspects of a software application has become an essential step in the software development process. It ensures that users get the best version of your product.

One of the common challenges when doing performance testing is the difficulty of correlating the metrics of your application with your testing results. Having available QA, infrastructure, and application metrics together allows engineering teams to better understand the behavior of their systems during the testing, helping to detect and prevent potential issues in their applications.

Many of the multi-faceted applications development teams deploy every day are loosely coupled and every service exists to power another service. Most teams developing fullstack applications know that testing the communication between these services essential. Part of the process is testing HTTP request endpoints, and this tutorial focuses on exactly that. I will lead you through learning how to extend the k6 framework to test our HTTP endpoints.

When your development team is under pressure to keep releasing new functionality in order to stay ahead of the competition, the time spent on quality assurance (QA) activities can feel like one overhead that you could do without. After all, with automated CI/CD pipelines enabling multiple deployments per day, you can get a fix out pretty quickly if something does go wrong – so why invest the time in testing before release? The reality is that scrimping on software testing is a false economy.

Over the last several decades, there has been a shift in the competency of software testing. Currently, testing does not include notifying the developer of any flaws found. It has a broad scope and is a phase that must be completed from the very beginning of a project’s development. The testing life cycle of an application has become more process-oriented and diverse due to agile. Typically, the SDLC is the only thing an organization focuses its attention on.

Hey Perplexed, We’re huge advocates for testing in production, and that includes performing chaos engineering/continuous verification in production. But you’re right to want to be cautious about exactly how you are performing these tests. After all, it’s chaos engineering, not just pure unbridled chaos.

When it comes to the applications, websites, and services we build, the end user ultimately determines whether or not the end product is successful. Even the greatest concepts can fall short if the application does not consistently meet the evolving needs and expectations of the user. Just look at what happened to sites like Myspace or Yahoo.

Development is no longer a linear journey from point A to point B. As more projects shift into a state of organic growth, user feedback and constant experimentation are increasingly becoming the norm, if not the standard for engineering. “In order to support this rapid experimentation, we’re beginning to embrace new working methods and practices,” said Vinodh Ravi, Executive Director of Platform Engineering at JPMorgan Chase.
