UI testing
UI (User Interface) testing, also known as GUI (Graphical User Interface) testing, involves testing the graphical elements of a software application to ensure that the user interface functions correctly and provides a positive user experience. It verifies that all elements on the interface are displayed correctly, respond appropriately to user interactions, and navigate between screens or pages seamlessly. UI testing may involve manual testing by human testers or automated testing using tools that simulate user interactions.
import React from 'react';
import { shallow } from 'enzyme';
import CustomUserList from './UserList'; // Changed the import name
test('renders custom user list correctly', () => {
const users = [{ name: 'Tom', age: 30 }, { name: 'GfG', age: 25 }];
const wrapper = shallow(<CustomUserList users={users} />);
expect(wrapper.find('li')).toHaveLength(2);
expect(wrapper.find('li').at(0).text()).toEqual('Gfg1 (30 years old)');
expect(wrapper.find('li').at(1).text()).toEqual('GfG (25 years old)');
});
Introduction to Testing in MERN
Testing in MERN (MongoDB, ExpressJS, React, NodeJS) applications is important for ensuring the reliability, functionality, and stability of your software. Testing helps identify bugs early in the development process, maintain code quality, and build confidence in your application’s behavior.
In this article, you will be walking through the basics of testing in MERN.
