Seed db with sequelize seed files before running tests with

Question

How do I do rake style commands in my test file (Jest) with sequelize seeder files?

I'm trying to do the same thing as this, but with sequelize.

describe('routes : movies', () => {

  beforeEach(() => {
    return knex.migrate.rollback()
    .then(() => { return knex.migrate.latest(); })
    .then(() => { return knex.seed.run(); });
  });

  afterEach(() => {
    return knex.migrate.rollback();
  });


});

I think you shouldn't make real DB requests while testing your code. Mock your DB request and return the data set from your mock function if it's needed. Otherwise, it looks like you testing a library, in your case this lib is knex .
