Use testing
Proper testing is crucial for maintaining the quality and stability of a large React application. This can include writing unit tests for individual components to ensure that they are working correctly, as well as integration tests for larger functionalities to ensure that everything is working together as expected. Testing can help to catch issues early on and prevent regressions as the application evolves, and can also help to ensure that changes to the codebase do not break existing functionality.
Example: Below is the code example
Javascript
import React from 'react';import { shallow } from 'enzyme';import MyComponent from './MyComponent';describe('MyComponent', () => { it('renders the correct text', () => { const wrapper = shallow(<MyComponent />); expect(wrapper.text()).toEqual('Hello World!'); });}); |
