We used Istanbul to generate code coverage reports in Popups. It's barely maintained now and broken.
The proposal is to switch to https://github.com/istanbuljs/nyc but it's not clear how to migrate that and whether it will work with our setup.
your mission if you chose to accept it - take some time to investigate whether this is feasible and what the challenges are for doing so
Right now, Joaquin is the only one who understands this so we need to knowledge share so he's not a single point of failure.
* Are there any challenges or changes needed with node-qunit
* Migration plan OR Gerrit patch showing the necessary changes
