Aurelia custom element tests unable to load view

Question

I'm facing problem while loading view in Aurelia test. Please refer below sample test code..

import {StageComponent} from 'aurelia-testing';
import {bootstrap} from 'aurelia-bootstrapper';

describe('MyComponent', () => {
  let component;

  beforeEach(() => {
    component = StageComponent
      .withResources('src/common/my-component')
      .inView('<my-component first-name.bind="firstName"></my-component>')
      .boundTo({ firstName: 'Bob' });
  });

  it('should render first name', done => {
    component.create(bootstrap).then(() => {
      const nameElement = document.querySelector('.firstName');
      expect(nameElement.innerHTML).toBe('Bob');
      done();
    }).catch(e => { console.log(e.toString()) });
  });

  afterEach(() => {
    component.dispose();
  });
});

I'm using karma for running tests with proxies as -

proxies: {
    '/base/jspm_packages/': '/base/wwwroot/jspm_packages/'
}

after running above test i'm able to load the view-model but it fails to load the view with following error -

LOG: 'Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:9876/base/src/common/my-component.html Error: XHR error (404 Not Found) loading http://localhost:9876/base/src/common/my-component.html Error loading http://localhost:9876/base/src/common/my-component.html!http://localhost:9876/base/jspm_packages/github/systemjs/plugin-text@0.0.8.js Error loading http://localhost:9876/base/src/common/my-component.html!template-registry-entry'

Thank you for you help in advance!

UPDATE --> Karma.conf.js file

module.exports = function(config) {
  config.set({

It might be that this line:

  serveFiles: ['src/**/*.js'],

should actually be this:

  serveFiles: ['src/**/*.js', 'src/**/*.html']

Normally your html would be bundled up with your component's js, but in this case you're serving the html directly.
