AFAIK, the previous two answers are correct in that you’ll want to run the tests in a browser; click DEBUG and view the output in the console.
Politely contradicting the previous answer, I regularly do this and step-through debug with full variable interaction using Karma.
The proper answer to your question, because what you want is pretty HTML based output, is “no.” However, this plugin for karma may give you the results you desire.
