I love how well it’s integrated, especially also with code coverage. So I hope someone has found a way to use it directly in WebStorm. Running tests just for those files that were changed (via --watch option) automatically or deciding to run specific tests is very easy in WebStorm.
Please note that my tests are running in WebStorm, following the Meteor guide, creating a configuration for it. But the output isn’t as pretty as I want it and using the IDE has more features (as mentioned above).
