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 clear 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 four easy steps: Importance of Test-Driven Development (TDD) Using TDD provides the following benefits: Why Should You Use Test-Driven Development (TDD) for ReactJS? If you have worked with ReactJS, then you probably know that code grows really fast in ReactJS. The code gets filled up with a lot of complex conditions due to service calls and change of state. Every component of your React application that lacks unit tests becomes a legacy code which is very difficult to maintain. Although we can add unit tests after we create the production code, it will be very risky as some scenarios can get overlooked which will cause the issue at the production stage. Setting Up The Environment for Test-Driven Development (TDD) The most important thing to do first is to set up the environment for writing...
We have heard from many people that there is so much work happening with React Native, it can be tough to keep track of what’s going on. To help communicate what work is in progress, we are now publishing a roadmap for React Native. At a high level, this work can be broken down into three priorities: If you have suggestions for features that you think would be valuable on the roadmap, check out Canny, where you can suggest new features and discuss existing proposals. What’s new in React Native Version 0.37 of React Native, released today, introduces a new core component to make it really easy to add a touchable Button to any app. We’re also introducing support for the new Yarn package manager, which should speed up the whole process of updating your app’s dependencies. Introducing Button Today we’re introducing a basic <Button /> component that looks great on every platform. This addresses one of the most common pieces of feedback we get: React Native is one of the only mobile development toolkits without a button ready to use out of the box. Experienced React Native developers know how to make a button: use TouchableOpacity for the default look on iOS, TouchableNativeFeedback for the ripple effect on Android, then apply a few styles. Custom buttons aren’t particularly hard to build or install, but we aim to make React Native radically easy to learn. With the addition of a basic button into core, newcomers will be able to develop something awesome in their first day, rather than spending that time formatting a Button and learning about Touchable nuances....
Cross-platform mobile app development – one of the most sought-after terms in the mobile app industry. Everyone likes to code and customize the mobile app. But keeping the same time and definitely the same code. Yes, write once and run everywhere is becoming not just the trend but the demand indeed and in need of today’s world. The cross-platform mobile apps are the all-new form of mobility. Technology means there should not be the barriers resisting the mobility and power of making codes flexible as much as possible. Here are the top five imperative tools to consider for Cross-Platform Mobile App Development: Xamarin: Xamarin is the most called platform for native mobile applications. The latest and advanced. Mainly used for easy access to data and building apps for almost every mobile platforms such as iOS, Android and Windows. Xamarin uses C# as the base language. The one who enjoys coding with C sharp can surely mingle up with this platform as a developer. Also, the Swift language is fine to use with this platform for programming for cross-platform apps. The platform allows using an integrated development environment and APIs directly into the Xamarin Studio. The mobile apps built with this platform are highly seamless and device friendly for many different devices. So we can consider Xamarin as playing the most vital role in defining the cross-platform apps. PhoneGap: PhoneGap is one of the open source platforms and it is completely free for developing cross-platform apps. It builds a single app that works with several platforms and easy to handle the programming part. Because of its library functions and easy...

Building your mobile application could be as easy as opening up the IDE, throwing a few things together, doing a fast round of testing, and submitting it to an App Store, all done in half day’s work. Or you can make it an extremely involved process involving rigorous up-front design, QA testing on a whole lot of devices, usability testing, a full beta lifecycle, and then deployment some different ways. The path you choose will give shape to your vision. With that said, here’s a look at the app development lifecycle and the objectives and challenges along the way. 1. The Research All apps start with an idea, even if yours is just to have a mobile app presence. Refine that idea into a solid basis for an application. Make sure your initial analysis includes actual demographics, motivations, behavior patterns and goals of your buyer persona. During each stage of the process, keep the end user in mind. Now, try to think of your customer’s lifecycle, once...
