Full rendering is also useful in use cases where the test components are wrapped in higher order components.įor Full rendering, it is required that the full DOM API is available at global scope. Setting Up the Environment for TDDįor this tutorial, we are using the following versions – from 'enzyme' Full Renderingįull rendering, or Full DOM rendering, is best for use cases that require interaction between components and DOM APIs. We need testing frameworks like Jest and Enzyme for implementing our test codes. The most important thing to do first is to set up the environment for writing and running our tests. Setting Up The Environment for Test-Driven Development (TDD) 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. The code gets filled up with a lot of complex conditions due to service calls and change of state.Įvery component of your React application that lacks unit tests becomes a legacy code which is very difficult to maintain. If you have worked with ReactJS, then you probably know that code grows really fast in ReactJS. Why Should You Use Test-Driven Development (TDD) for ReactJS? It enables developers to write small test codes which are easy to debug.You have a clear picture of what you are trying to build before you write the actual code.Using TDD provides the following benefits: Importance of Test-Driven Development (TDD) Repeat the process – Now repeat this process for every new feature you introduce in the application.Refactor your code – Improvise on the code quality.Run the test – Write the minimum code required to pass the test.Write a test – First, you are going to write a test for every possible challenge.Test Driven Development can easily be compiled in four easy steps: It is a cyclic process and each cycle starts by writing a unit test. The primary aim of TDD is to write code which is clear and bug-free.Īs a developer, you need to write tests for every small functionality of the application.
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. There are many tools available for unit testing in ReactJS but we will be going through Enzyme and Jest. Step 1: We are going to render a simple button named Click Me using the following code.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).

Npm install –save-dev enzyme-adapter-react-16įollow these steps to write a test case in your React application. To get started with Enzyme, install it via npm with the following command. It helps render React components in testing mode. EnzymeĮnzyme is a JavaScript testing utility for easily testing React components. When we run the create-react-app command, it will automatically install Jest in our React application. Note: We need to install Jest before writing any test cases. Jest is a JavaScript testing framework written by Facebook. We are going to use the following popular unit testing libraries in our React application: create-react-app my-app -template typescript Step 2: Use the following commands to set up a basic React project. Step 1: Install the create-react-app npm package with the following command in the desired location.

It is used by thousands of developers around the world to create complex and multifaceted applications. In this article, we will discuss unit testing in React and how to implement it using the Jest and Enzyme frameworks. React is an open-source framework for building reusable UI components and apps.
