How to test a unhandledRejection / uncaughtException handler with jest

Question

I have handlers for unhandledRejections and uncaughtExceptions:

bin.js

[\'unhandledRejection\', \'uncaughtExce         


        

Answer 1

putting it inside try catch will help:

const error = new Error('mock error');

try {

await Promise.reject(error);

} catch(error){

   expect(logger.error).toHaveBeenCalledWith(error);

}
