Aurelia Unit Testing error due to aurelia.setRoot('shell/shell'); - unit-testing

Question

I'm trying to implement unit test on login method but I'm getting "Cannot read property 'setRoot' of undefined" error.
Here is my Login Method:
import { inject, Aurelia, NewInstance, computedFrom } from 'aurelia-framework';
import { Router } from 'aurelia-router';
import { Server, User } from 'backend/server';
import { ValidationRules, ValidationController, validateTrigger } from 'aurelia-validation';
import { ValidationRenderer } from 'resources/validation-renderer';
#inject(Aurelia, Router, Server, NewInstance.of(ValidationController), NewInstance.of(User))
constructor(aurelia, router, server, validationController, user) {
this.router = router;
this.aurelia = aurelia;
this.validationController = validationController;
this.server = server;
this.user = user;
}
activate() {
this.validationController.validateTrigger = validateTrigger.blur;
this.validationController.addRenderer(new ValidationRenderer());
ValidationRules
.ensure(u => u.email)
.required()
.matches(/^(([^<>()\[\]\\.,;:\s#"]+(\.[^<>()\[\]\\.,;:\s#"]+)*)|(".+"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/)
.ensure('password')
.required()
.on(this.user);
}
logUserIn()
{
let promise = new Promise((resolve, reject) =>
{
this.loggingIn = true;
this.messageColor = 'green';
this.message = 'Authenticating...';
this.loginSuccess = false;
this.validationController.validate().then(errors => {
if (!errors.valid) {
this.loggingIn = false;
return ({error: true});
}
return this.server.authenticate(this.user.email, this.user.password);
}).then(result => {
if (!result.error) {
this.messageColor = 'green';
this.message = 'Login Successful';
this.loginSuccess = true;
this.aurelia.setRoot('shell/shell');
resolve(result);
} else {
this.message = '';
resolve();
}
}).catch(err => {
if(!this.loginSuccess)
{
this.messageColor = 'red';
this.message = err.message;
}
this.loggingIn = false;
resolve(err);
});
});
return promise;
}
My unit test code:
login.spec.js:
describe('Login Unit Test', () => {
var login = new Login();
login.validationController = new ValidationController();
login.server = new Server();
it("shouldn't allow login", (done) => {
console.log(login.messageColor);
login.logUserIn().then((result) => {
console.log(login.messageColor);
console.log(login.message);
expect(login.messageColor).toBe('red');
done();
});
});
it("Should log in", (done) => {
login.user = {email:'a#b.com', password:'abc'};
console.log(login.user.email);
console.log(login.user.password);
login.logUserIn().then((result) => {
console.log(login.messageColor);
console.log(login.message);
expect(login.messageColor).toBe('green');
done();
});
});
});
Here is the error that i'm getting
I would really appreciate any help.
Thanks.

Did you post exactly the Login code?
In this case before the constructor the #inject statement is missing.
Some like:
#inject(Aurelia, Router, Server, ValidationController, User)
constructor(aurelia, router, server, validationController, user)
