node.js - mysql2 connection.connect() გაჩერებულია typescript jest ტესტში macOS-ზე
ვცდილობ, შევქმნა mysql2 კავშირი ადგილობრივ mysql მონაცემთა ბაზასთან jest ტესტში macOS-ზე,
გარემო :
- MacOS: ჰაი სიერა (10.13.6)
- MySQL: 8.0.18
- TypeScript: 3.7.2
- mysql2: 2.0.1
- nodejs: v10.16.3
მე ვიყენებ promise-Wrapper-ს. კოდი გამოიყურება ასე:
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;
}
მე უკვე დავამატე დებაგირების ოპცია და ეს არის შედეგი:

როცა mysql-ში ვატარებ show process list, ვხედავ ახალ პროცესს Command 'Sleep'-ით (სტატუსი ცარიელია და ინფორმაცია ნულია).
არაფერია?

თქვენ უნდა უზრუნველყოთ, რომ node იყენებს სისტემურ დროს და არა ყალბ ტაიმერებს. დაამატეთ ქვემოთ მოცემული სტრიქონი იმპორტების შემდეგ ტესტის ფაილში
jest.useRealTimers();
ან უკეთესი, თქვენ შეგიძლიათ დაადო ტაიმერები რეალურზე თქვენს jest კონფიგურაციაში
"timers":"real"
