Writing Easily Testable Code with Stateless Components in React.js

Writing Easily Testable Code with Stateless Components in #React.JS  #javascript #testing

  • By relying on pure components, developers end up writing reusable code that’s extremely easy to test, which leads to better application architecture.
  • Personally, I like the term “pure component” because it’s indicative of what the code really is — a pure function sprinkled with some JSX.
  • In addition to these benefits, pure components also make it extremely easy to test code with any crazy props that you wish.
  • Like a pure function, pure components will always map the same input to the same output, therefore, if we can think of the scenario, we can test how our component will react.
  • As we just saw, the code for functional components provides us awesome intel for everything we need to know in order to write effective tests.

Functional Stateless Components provides clean syntax that allows us to
write more declarative code. We will look at stateless components and finish up with some unit tests in this article.

React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
