node.js - mysql2 connection.connect() se queda colgado en prueba de jest con TypeScript en macOS
Estoy intentando crear una conexión mysql2 a una base de datos mysql local en un test de jest en macOS usando TypeScript. Y la llamada a connect() se queda colgada.
Entorno :
- MacOS: High Sierra (10.13.6)
- MySQL: 8.0.18
- Typescript: 3.7.2
- mysql2: 2.0.1
- nodejs: v10.16.3
Estoy usando el envoltorio de promesas. El código se ve así:
import { createConnection, ConnectionOptions, Connection } from 'mysql2/promise'
...
async openConnection(options: ConnectionOptions): Promise<Connection> {
console.log('About to create mysql connection using options ', options);
const connection = await createConnection(options);
console.log('Connection created => about to call connect()');
await connection.connect();
console.log('Connection created => connect() returned'); // this line is never reached!
....
return connection;
}
Ya agregué la opción de depuración y este es el resultado:

RUNS src/tests/mysql/mysql-connection.spec.ts
Cuando ejecuto un show process list en mysql, veo un nuevo proceso con Comando 'Sleep' (el estado está vacío y la información es nula).
¿Alguna idea?

Necesitas asegurarte de que Node esté usando la hora del sistema y no temporizadores falsos. Agrega la siguiente línea inmediatamente después de tus importaciones en el archivo de prueba
jest.useRealTimers();
O mejor aún, puedes configurar temporizadores para ejecutar en tu configuración de jest
"timers":"real"
