In this guide, we’ll walk you through the steps to create a self-signed SSL certificate for your React JS application using mkcert . Step 1: Install Chocolatey Cho...

Creating Unit Test Cases in React JS with Jest and React Testing Library Creating Unit Test Cases in React JS with Jest and React Testing Library In this article, you will get an understanding of how we can create a basic unit test case in React JS. Creating automated test cases for a React application involves using testing libraries and frameworks like Jest and React Testing Library. For testing a LoginForm component, you would want to cover different scenarios like valid and invalid inputs, form submission, error handling, and more. Below, I'll provide an example of how to create test cases using Jest and React Testing Library. LoginForm Component Let's assume your LoginForm component looks something like this: import React, { useState } from 'react'; const LoginForm = ({ onLogin }) => { const [email, setEmail] = useState(''); const [password, setPassword] = u...
