JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
enzyme-adapter-react-16
Advanced tools
The enzyme-adapter-react-16 package is an adapter that is used with the Enzyme testing utility for React. It is specifically designed to work with React version 16. This adapter configures Enzyme to be compatible with the React 16 version's API and environment. It allows developers to mount React components for testing purposes, simulate events, and inspect the component hierarchy.
Configuration
This code configures Enzyme to use the React 16 adapter, which is necessary to test React components built with React version 16.
const Enzyme = require('enzyme');
const Adapter = require('enzyme-adapter-react-16');
Enzyme.configure({ adapter: new Adapter() });
Shallow Rendering
Shallow rendering is used for testing components in isolation from the children they render. This is useful for unit testing components without worrying about the behavior of child components.
const { shallow } = require('enzyme');
const MyComponent = require('./MyComponent');
const wrapper = shallow(<MyComponent />);
Full DOM Rendering
Full DOM rendering is ideal for use cases where you have components that may interact with DOM APIs or need to test components in an environment that is closer to the browser environment.
const { mount } = require('enzyme');
const MyComponent = require('./MyComponent');
const wrapper = mount(<MyComponent />);
Static Rendering
Static rendering is used to render components to static HTML and analyze the resulting HTML structure. It's useful for generating HTML from your components and for analyzing the structure of the rendered components.
const { render } = require('enzyme');
const MyComponent = require('./MyComponent');
const wrapper = render(<MyComponent />);
React Testing Library is a very popular testing utility that encourages better testing practices by focusing on testing components the way users would use them. Unlike Enzyme, it does not provide shallow rendering and it avoids direct access to the component's internal state.
Jest-Enzyme is an extension to the Jest testing framework that provides additional matchers for Enzyme, making it easier to write tests. It complements Enzyme but does not replace the need for an adapter.
