There’s no doubt which programming language is winning the battle for global supremacy right now. JavaScript has powered past the 12 million developers mark, and 5 million of its loyal fans (some 40%) have come aboard within the last three years. Initially thought of as merely a Java spin-out, it is now used to power everything from machine learning libraries to space exploration robots. But to truly maximize the potential of JavaScript, developers have to implement an effective testing regime.

Every Rails app has a breaking point; a level of activity that it simply cannot handle. Your braking point depends on big architectural decisions, yes — and also on the tiniest changes committed by your most junior developer. That's why it's vital to regularly test your application's performance under load. In this article, Milap Neupane gives us a Rails-centric introduction to load testing with a powerful open-source tool called JMeter.

Teams have been testing software for as long as software has existed. With the increased adoption of continuous integration and delivery, automated tests are becoming essential. Behaviour-driven development (BDD) is a modern approach to developing software that grew out of Agile and test-driven development. Most teams/organisations can benefit from test management and BDD, but BDD adoption is much more than simply managing tests – automated or manual.

Since the beginning of the internet era, browsers and websites have lived co-dependently. Starting from the internet explorer, then to the Mozilla project and now to at least six major browsers in the market, we have evolved quite well. But browsers and web development technologies do not seem to be in a happy relationship. To ease out the web development, developers think of new ways to have a dedicated and organised system of sustainable websites such as subgrids. Result?

Cross browser testing can be a real headache for a software tester. You may have tested your application on the latest versions of Chrome, Firefox, and Edge, but more often than not, some browsers such as Internet Explorer, Opera Mini, UC Browser get missed out. As a result of this, a portion of your users will not be able to view your product properly. Thanks to the cross-browser testing tools available in the market, now the cross-browser testing efforts can be significantly reduced.

Cross Browser Testing is adopted by developers in order to ensure that an application works as intended across all combinations of devices and browsers. This will help developers to reveal issues that might have been left ignored or uncovered otherwise. Each browser comes with an exceptional blend of web support but also has certain drawbacks.
