Unit testing with Jest and Sequelize - Test passing when it shouldn't - node.js

Question

I'm trying to write some unit tests, and at first they appeared to be working, but then I realized some of them were passing when they definitely shouldn't be, and I've included one such example from my code of a test passing when it shouldn't:
controller.js
const userModel = require('../models').users;
module.exports = {
async getUserByID(req, res) {
try {
var user = await userModel.findOne({
where: { id: req.params.id }
});
res.status(201).send(user);
catch (error) {
res.status(500).send(error)
}
}
}
controller.test.js
const controller = require('../controllers/controller');
const httpMocks = require('node-mocks-http');
//mock for main model that my controller function uses
jest.mock('../models/users', () => {
const SequelizeMock = require('sequelize-mock');
const dbMock = new SequelizeMock();
return dbMock.define('users', {
id: 1,
name: 'Tony',
email: 'test1#gmail.com',
uid: '12345'
})
});
//mock for model that's associated to my users model
jest.mock('../models/user_prefs', () => {
const SequelizeMock = require('sequelize-mock');
const dbMock = new SequelizeMock();
return dbMock.define('user_prefs', {
id: 1,
uid: '12345',
notification_settings: {}
})
});
//the actual test
describe('getUserByID', () => {
it('should get user from mock', () => {
var req = httpMocks.createRequest({
params: {
id: 1
}
});
var res = httpMocks.createResponse();
controller.getUserByID(req, res).then(function(user) {
expect(user.name).toEqual('Steve');
})
});
});
package.json
"scripts": {
"test": "jest --config ./jest.config.js --forceExit --coverage"
}
jest.config.js
module.exports = {
testEnvironment: "node"
}
When I run npm test everything runs just fine, but it tells me that the test passes, even though it obviously shouldn't if it was correctly retrieving the data from the mock, and I can't really figure out why.
