Selenium is an open-source automation framework initially introduced in 2004. Using this framework, we can validate web applications across different browsers and platforms. Java, C#, Python are mostly used for developing test scripts. Testing performed using Selenium are generally referred to as Selenium testing. The initial version released is just a single tool, but the latest version is now not only a tool — it’s a software suite with a pack of IDE, RC, and WebDriver.

While the term reactive architecture has been around for a long time, only relatively recently has it been recognized by the industry and hit mainstream adoption. And the goal of this article is to analyze what reactive really is and why to adopt it. Its core meaning has been formalized with the creation of the Reactive Manifesto2 in 2013, when Jonas Bonér collected some of the brightest minds in the distributed and high-performance computing industry – Dave Farley, Roland Kuhn, and Marti

There has been quite a bit of talk lately about how companies are moving to remote work. Some people even go so far to say that all companies should be remote. Having an office is just clinging to the past. The office is obsolete and remote work is the future we should have. I can’t disagree more. As far as software development is concerned, I think the most efficient teams in the future will be in the office.

Java comes with a built-in multi-threading model based on shared data and locks. To use this model, you decide what data will be shared by multiple threads and mark as “synchronized” sections of the code that access the shared data. It also provides a locking mechanism to ensure that only one thread can access the shared data at a time. Lock operations remove possibilities for race conditions but simultaneously add possibilities for deadlocks.

Our digital world is evolving and advancing at an unimaginable pace – and so are the expectations of end users. Momentum is everything in today’s united world, and having a poor performing website or application will likely result in the confidence of your products and services.
