const domino = require('domino'); const fs = require('fs'); const path = require('path'); // Use the browser index.html as a template for the mock window const template = fs .readFileSync(path.join(join(process.cwd(), 'dist/yourprojectname/browser'), 'index.html')) .toString(); // Shim for the global window and document objects. const window = domino.createWindow(template); global['window'] = window; global['document'] = window.document;
