Sequelize with postgres leaves jest hanging after all tests executed

Hello, I have made a sscee for this issue:

1. clone the following repo: https://github.com/LaurentVB/sequelize-hanging-test
2. npm install
3. setup an empty postgresql DB named ‘test’, accessible by ‘root’ without password
4. npm test

What do you expect to happen?

The test executes and the prompt returns.

What is actually happening?

After all tests pass, the execution of jest hangs until it’s killed with CTRL+C. The same test with an embedded in-memory sqlite DB behaves as expected.

Dialect: postgres Sequelize version: 3.24.6

This is not working anymore. Using latest version of jest and sequelize, jest still hangs after calling sequelize.close()

Hmm yeah, I see that behaviour as well - I’ve never seen it happen in mocha tests, so it must be something jest is doing 😃

Adding

afterAll(function () {
 sequelize.close();
});

works fine though
