As indicated in this stackoverflow answer, it looks like Karma will serve JSON fixtures. However, I\'ve spent too many hours trying to get it to work in my environment. Re
Your problem is that 'false'
has to be a boolean, not a string.
There is already an issue to validate the config better and fix such a mistakes.
Also, you might write a simple "json" preprocessor (similar to karma-html2js) that would make it valid JS and put the JSON into some global namespace so that you can keep the tests synchronous...
