Readme

Objection transactional tests
Run tests in Jest or Mocha in Objection.js transactions. This starts a new transaction at the beginning of each tests and does a rollback at the end of it, reverting the database to the state it was in before the test.

Usage

import { transactionPerTest } from "objection-transactional-tests";

describe("examples", () => {
  transactionPerTest();
  it("database interactions", () => {
    // do something that touches database
  });
});

Note that any database changes done in beforeAll won't be cleaned up.
The setup can be added to test setup script to apply it automatically for all tests. This will ensure that no test pollute the test database, but also adds overhead to tests that do not use the database.
