Jest : testing simple class with Store dependency - reactjs

Question

I having a hard time understanding why my mocked method isnt returning the value I specified with mockReturnValue. I am testing a simple method that checks a helper on a store to see if a user is authenticated before proceeding. See connectIfAuth below.
'use strict';
var AuthStore = require('../stores/AuthStore');
console.log('top ' + AuthStore.isAuthenticated());
var TestClass = {
connect() {
//...use a mock
},
connectIfAuth() {
console.log('in connect if: ' + AuthStore.isAuthenticated());
if (AuthStore.isAuthenticated()) {
this.connect();
}
}
};
module.exports = TestClass;
In my test, I want to make the mocked method from the store return true/false and test that the connect() method is called/not-called but the method returns undefined within the method I am testing.
'use strict';
jest.dontMock('../TestClass.js');
var AuthStore = require('../../stores/AuthStore');
describe('TestClass', function() {
var TestClass;
var connectMock;
beforeEach(function() {
//the store should return true
AuthStore.isAuthenticated = jest.genMockFunction().mockReturnValue(true);
//do I have to require this after I mock out the method(s) in AuthStore?
TestClass = require('../TestClass');
connectMock = jest.genMockFunction();
TestClass.connect = connectMock;
});
it('should return the mocked value', function(){
TestClass.connectIfAuth();
expect(connectMock.mock.calls.length).toBe(1); //is 0
});
});
My test output is:
FAIL src/scripts/api/tests/TestClass-tests.js (0.121s)
top undefined
in connect if: undefined
● TestClass › it should return the mocked value
Expected: 0 toBe: 1

In case anyone comes across this same problem - I solved this by putting all of my requires statements outside of the describe/it blocks. Similar to this question, but I also ended up require-ing the module I was testing at the top of the file. I assume I'll have to closely manage the beforeEach and afterEach methods to clean up the mocks I use within my tests.
