Exploring the capabilities of a Vue.js component

I am currently facing some challenges while trying to test a Vue.js component. My main issue lies in setting a property for the component and verifying that it has been set correctly. For context, the module has been loaded with exports and the JavaScript is being output through Webpack.

// sample-component
exports = module.exports = {};

module.exports = {
  data: function () {
    return {
      isActive: false
    };
  },
  methods: {
    'toggleActiveState': function () {
       console.log(this.isActive); // -> true
       this.isActive = !this.isActive;
       console.log(this.isActive); // -> false
    }
  }
};

// test-case
var myComponent = require('../../resources/src/js/components/_sample-component.js');
var assert = require('assert');

describe('toggleActiveState()', function () {
  beforeEach(function () {
    myComponent.data.isActive = true;
  });
  it('should toggle the active state of the component', function () {
    console.log(myComponent.data.isActive); // -> true
    myComponent.methods.toggleActiveState();
    console.log(myComponent.data.isActive); // -> false
    assert.equal(myComponent.data.isActive, false);
  });
});

If you're looking for a clue on how to properly test loading vue components, consider the following example;

const myComponent = require('../../resources/src/js/components/_component.js');
const assert = require('assert');         

 //load the component using a Vue instance
vm = new Vue({
    template: '<div><test v-ref:test-component></test></div>',
    components: {
        'test': myComponent
    }
}).$mount();

const componentInstance = vm.$refs.testComponent;

describe('close()', function () {
    beforeEach(function () {
        componentInstance.active = true;
    });

    it('should set the component to inactive', function () {
        console.log(componentInstance.active); // -> true
        componentInstance.close();
        console.log(componentInstance.active); // -> false
        assert.equal(componentInstance.active, false);
    });
});
