Web performance is a broad topic, and you will find no lack of performance testing tips and tutorials all around the net. Before beginning tuning your site or application, you have to first figure out which metrics matter to your own users and establish a few achievable benchmarks. What is performance testing?  In the context of web development, performance testing entails using software tools to simulate the way the application runs under particular conditions. After the word"performance" is heard, most people instantly think of the rate. Fast load times and response times are absolutely necessary these days, but you have to consider the larger picture, which requires more than simply clicking through all your links to be certain they work. Just because everything works flawlessly during production testing does not mean that will be the situation as soon as your site is flooded with traffic. What are the advantages of performance testing?  Testing the operation of your site ...

The disagreement over whether to write a unit test or an end-to-end evaluation for an element of a software system is something I have encountered a number of times. It mostly appears as a philosophical conversation along the lines when we can only write one test for this feature, should we write a unit test or an end-to-end test? Basically, time and resources are limited, so what type of test would be most effective? In this article, I'll provide my view on this question. I must be aware that my experience has been in building software infrastructure for industrial applications -- streaming data system for near-real-time data. For someone who has worked in another domain, where calculating and analysing the whole software process is simpler, or at which the functional environment is more forgiving of mistake, I could understand the way their experience might be different. I've worked on hosted solutions in addition to infrastructure that's installed on-premises and operate...

Learning to build code, if through self-study or a computer science degree, isn't the same as learning how to construct applications, especially in a changing company setting. Your research may have instructed you what code has to be composed to construct a better piece of software, however, they probably did not teach you the way a team of engineers should think about writing that code. How does the work get divvied up? What does the development cycle look like? How can quality management work? Over the past 60 decades, many methodologies have tried to define exactly how teams can maximise their software development, however, the one which reigns supreme--at least over the past twenty years--is the agile methodology. Emphasising speed, adaptability, and user-centric layout, the agile technique is the backbone of contemporary software development. Most of the popular project management tools you've likely used (like Trello and Jira) are based entirely on their features. If you...
