使用--detectOpenHandles参数运行测试后,出现以下错误
Jest has detected the following 1 open handle potentially keeping Jest from exiting:
● PROMISE
18 |
19 | mongoose.Promise = global.Promise;
> 20 | mongoose.connect(config.database.link, config.database.options);
| ^
21 |
22 |
23 | app.use(cors());
但是我的测试包括mongoose.deisconnect()
afterAll(() => {
return new Promise(res => mongoose.disconnect(() => {
res();
}));
});
我试图将afteAll函数更改为类似的内容
afterAll(async () => {
await mongoose.disconnect();
await mongoose.connection.close();
});
我也尝试在afterAll()内部调用con.disconnect
app.con = mongoose.connect(config.database.link, config.database.options);
// inside of afterAll
app.con.disconnect()
但是我仍然看到此错误
该如何解决?
