A single report for all browsers.

Great, thanks for opening this. Please let me know if I can help at all.

Yeah, I'm interested in this as well, though my interest is a little different.

I'd like to see combination of the coverage report across unit tests + E2E tests for instance. That would necessitate some sort of task outside of Karma to munge the JSON together.

So if / when this gets built, it might be useful to have the lcov merging in a separate lib.

I'm also interested to see that coming.

For now I'm using a dumb shell script + lcov to merge reports : https://gist.github.com/xseignard/5420661 so then I can use Sonar to have a clean quality dashboard for my node,angular and plain js projects. See: https://github.com/xseignard/sonar-js as a simple demo

I have done some experiment with https://github.com/mweibel/lcov-result-merger it works pretty well.
