According to Michael Feathers – “Any code that has no tests is a legacy code”. So as a developer it is your duty to avoid creating legacy code by using test-driven development (TDD) . There are many tools available for unit testing in ReactJS but we will be going through Enzyme and Jest . What is Test-Driven Development (TDD)? Test-Driven Development (TDD) is a programming practice which enables developers to write code only if an automated test has failed thereby avoiding duplication of the code. The primary aim of TDD is to write code which is clearer and bug-free. As a developer, you need to write tests for every small functionality of the application. It is a cyclic process and each cycle starts by writing a unit test. Test-Driven Development can easily be compiled in 4 easy steps – 1. Write a test – First, you are going to write a test for every possible challenge. 2. Run the test – Write the minimum code required to pass the test. 3. Re...

Today, I will be discussing with you the future of Operating System – Fuchsia OS. I will be discussing everything, right from the point, it started to the current stage it has reached right now. The blog will act as a complete guide to Fuchsia OS , and I will keep updating it with all the future updates happening around Fuchsia. So without further ado, let’s get started. Why did Google decide to go for Fuchsia OS? Kernels act as the core of any operating system that provides the primary mechanism around which the complete OS can be built. A lot of problems posted by Android comes from the fact that it is based on the Linux kernel which was never intended for phones. Even the Android OS was initially built for digital cameras. The next biggest downside of Android is fragmentation. Fragmentation is the only reason why a lot of these smartphones don’t perform to the level of their hardware capabilities. The reason fragmentation exists is because Android is a huge mess. A...
