Any idea what could cause this error? This is an angular 2 application built with angular cli directly inside maven, using frontend-maven-plugin inside a spring boot app. But the angular 2 application could be also built separately using only node, npm and ng.

You have not provided your karma.conf.js in question description. Please check it must include:-

 frameworks: ['jasmine', 'requirejs']

in config set section.
