objection-transactional-tests's Issues

Support for Jest 27+

Jest 27 doesn't support dynamically creating before<Each/All> and after<Each/All> hooks so this library no longer works. We get

Cannot add a hook after tests have started running. Hooks must be defined synchronously.

Creating this issue in case anyone else is using this library and wants to upgrade to Jest 27+. You can see my full changes in https://github.com/BlockedTODO/BlockedTODO/pull/667/files but to summarize what I do:

In jest.config.js, add this line

setupFilesAfterEnv: ['./jest.setup.js'],

in jest.setup.js:

import objection from 'objection';
import knex from './src/db/index.js'; // Change src/db/index.js to the path to the file where you export your knex instance

const {transaction, Model} = objection;

global.beforeAll(async () => {
    global.knex = knex;
    global.txn = null;
});

global.beforeEach(async () => {
    global.txn = await transaction.start(knex);
    Model.knex(global.txn);
});

global.afterEach(async () => {
    await global.txn.rollback();
    Model.knex(knex);
});

global.afterAll(async () => {
    global.knex.destroy();
});

Note: this will create a transaction for every single unit test, which may not be desirable in everyone's case.
