Answer: This turned to be a completely different problem. Vague karma/chai error messages led me in the wrong direction. The actual problem (if someone bumps into this issue again, which I believe they will..) is the bind method. Turned out the phantomjs```` The headless browser we are running the tests with, Doesn't supportbind``` (as some other es5 methods, not all). Running the same tests with chrome/firefox works perfectly. Once I understood this was the problem, then solving was easy, just added an ES5-shim lib (that included bind) to the karma.conf.js configuration as an included file (or the way you add helpers in any other framework) and everything works perfectlly
