How to get better test reports in the console?

Fixed by installing the karma-spec-reporter

npm install karma-spec-reporter --save-dev

and adding this my karma.config.js

reporters: ['spec'],

According to karma documentation

By default, Karma loads all NPM modules that are siblings to it and their name matches karma-*.

but some users have had to add the following to their config

plugins: ['karma-spec-reporter']
