Package Exports

chai-equal-jsx

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (chai-equal-jsx) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

chai-equal-jsx

Adds equalJSX and includeJSX methods to chai assertions. Uses Algolia's react-element-to-jsx-string under the hood.

Setup

import React from 'react';
import chai, { expect } from 'chai';
import equalJSX from '../chai-equal-jsx';

chai.use(equalJSX);

Usage

The following tests are all passing:

Expect

class TestComponent extends React.Component {}

// equalJSX
expect(<div />).to.equalJSX(<div />);
expect(<TestComponent />).to.equalJSX(<TestComponent />);

expect(<div />).to.not.equalJSX(<span />);
expect(<TestComponent />).to.not.equalJSX(<span />);

// includeJSX
expect(<div><TestComponent /></div>).to.includeJSX(<TestComponent />);
expect(<div><TestComponent /><span /></div>).to.includeJSX(<span></span>);

expect(<TestComponent />).to.not.includeJSX(<span></span>);
expect(<div><span /><TestComponent /></div>).to.not.includeJSX(<a />);

Should

chai.should();

class TestComponent extends React.Component {}

// equalJSX
(<div />).should.equalJSX(<div />);
(<TestComponent />).should.equalJSX(<TestComponent />);

(<div />).should.not.equalJSX(<span />);
(<TestComponent />).should.not.equalJSX(<span />);

// includeJSX
(<div><TestComponent /></div>).should.includeJSX(<TestComponent />);
(<div><TestComponent /><span /></div>).should.includeJSX(<span></span>);

(<TestComponent />).should.not.includeJSX(<span></span>);
(<div><span /><TestComponent /></div>).should.not.includeJSX(<a />);
