The issue I see with this is that the HTML5 spec isn't close to finalized, so we might be jumping the gun. That being said even if it was finalized this wouldn't solve the spec as it allows HTML, JS, and CSS. Yours would only take into consideration the HTML side, not the JS side of things. I would suggest adding in JS and test with that as well so it covers what's part of the current spec (as written today).

Spec:

This patch intends to address the problem of including HTML in karma tests which is impossible today without using html2js. There are already standard mechanisms to include CSS and JS that karma can continue using.

@morethanreal Thanks!

If html2js or ng-html2js preprocessor is used, the served path is changed to *.html.js, so this change does not affect that case.
