tests/DiagramModel.test.ts

import { DiagramModel, NodeModelGenerics } from '@projectstorm/react-diagrams'

test('importing react diagrams', () => {
	// Uncomment this to make test fail!
    // DiagramModel
});

Throws

 ReferenceError: self is not defined

Fixed with this jest.config.js:

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'jsdom',
};
