Accessing the webcam during testing

[carpiediem]

I'm developing a library that activates a user's webcam and analyzes the captured images. I'd like to test that portion of my code in mocha, but I'm not sure how. I don't imagine it will be possible in the command line (npm test). The browser-based test runner (npm run test-browser) seems plausible, except that it loads with the file:// protocol, instead of localhost. That means the browser prevents the code from accessing the webcam.

Any reccomendations on modifying this boilerplate to run the test runner at http://localhost/test/runner.html (or similar) instead of file:///path/to/project/test/runner.html? Thanks.

I've tried integrating karma, as a replacement, but so far I'm not able to get tests run by karma to inject the <script> element I need.
