I couldn’t find an acceptable Vim errorformat for when running Jasmine tests with quickfix (specifically using Jasmine’s ConsoleReporter), so I made my own.
If any of that made sense this may be of some use to you 
set errorformat=%E\ \ %.%#Error:%m,%-G%.%#/jasmine.js:%.%#,%C\ %#at\ %.%#\ (%f:%l:%c)
