I've been missing the nice specification report jasmine used to give when running it without karma, so I tried my hand at writing a plugin:
I haven't used nodejs before, and I didn't have time to learn anything in-depth, so this should be considered a quick-and-dirty implementation.
I took the karma-junit-reporter, took out what I didn't need, renamed a few things, and added my stuff. The reporter basically produces a POJO model of the test runs and then uses a mustache template to render to html. The template is an incomplete ripoff of the native jasmine report, however you can make your own template (in mustache) and pass it in to the templatePath config option.
