Mocha Chai vue testing a vue component : this.$notify is not a function - unit-testing

Question

I'm using this component : https://github.com/euvl/vue-notification
Since then, all of my Mocha chai test units are failing .
this.$notify is not a function
This is my login spec :
// Importing The testing library
import { expect } from "chai";
import { mount } from '#vue/test-utils'
// Importing The component I need to test
import Login from "#/components/Login.vue";
// Mounting the component as in real life
const wrapper = mount(Login);
describe("Login test", () => {
it("getAuth() to be a function", () => {
expect(wrapper.vm.getAuth).to.be.a("function");
});
});
I've tried out mount, shallowMount, render with no luck .
Any workaround ?
I'm calling vue-notification in main.js like this :
import Notifications from "vue-notification";
Vue.use(Notifications);
Thank you !
EDIT :
Ive tried to add
const $notify = require('vue-notification')
To my Login.vue component with no luck
EDIT 2 : Tried to call the function like this with no luck :
this.$root.$notify({
group: 'foo',
title: 'Hello ',
text: 'Cool'
});
[Vue warn]: Error in mounted hook: "TypeError: this.$root.$notify is not a function"

*EDIT : ***** Resolved by me ****** *
I was badly importing vue . Please see my working login.spec.js testing file there :
// THE ASSERTION LIBRARY
import { expect } from "chai";
// THE TESTING LIBRARY
import { mount } from "#vue/test-utils";
// THE COMPONENT THAT I WANT TO TEST
import Login from "#/components/Login.vue";
// THE EXTERNAL COMPONENTS LINKED TO MY LOGIN COMPONENT THAT I NEED TO JOIN
import Vue from 'vue';
import Vuelidate from 'vuelidate'
Vue.use(Vuelidate)
import {
required,
minLength,
between
} from "vuelidate/lib/validators";
import Notifications from "vue-notification";
import velocity from 'velocity-animate'
Vue.use(Notifications, { velocity });
// THE WRAPPER CONTAIN MY LOGIN MOUNTED COMPONENT, JUST LIKE IN THE REAL LIFE
const wrapper = mount(Login)
describe("Login test", () => {
it("getAuth() to be a function", () => {
expect(wrapper.vm.getAuth).to.be.a("function");
});
});
