In order to fix that over inside user.test.js, we're going to add a beforeEach call, which we've used in the past. The beforeEach call, as we know, is going to get called before every single test case. It's going to help us initialize some data. Now the data we're going to initialize is going to be defined just above the beforeEach call, in a variable called users:

describe('Users', () => {  var users; beforeEach(() => ...
