Currently facing a test challenge:
import { convertHeicToPng } from './heicUtils';
class Employee {
url: string;
onmessage: (m?: any) => void;
constructor(stringUrl: string) {
this.url = stringUrl;
this.onmessage = () => {};
}
postMessage(msg: any) {
this.onmessage(msg);
}
}
(window.Employee as any) = Employee;
describe('testing heicUtils', () => {
test('HEIC to PNG conversion should be successful', async () => {
const file = new File([''], 'test.heic', { type: 'image/heic' });
const base64 = await convertHeicToPng(file);
expect(base64).toContain('data:image/png;base64');
});
});
In the heicUtils module, integration with heic2any is established, utilizing WebWorkers. How can I effectively simulate a Worker for Jest testing?
