After running grunt karma, getting below error, the only change which I made, was upgrading the node packages.
"grunt-contrib-jasmine": "~0.8.2",

"karma-chrome-launcher": "~0.1.12",
"karma-firefox-launcher": "~0.1.6",
"karma-jasmine": "~0.3.5",
"karma-phantomjs-launcher": "^0.2.0",

Hope to get some pointers to resolve the same.
P.S. It's been running fine if I use karma using 'karma start test/karma.conf.js' from the terminal. But I have been trying to kick off karma through grunt-karma task as well and that's where it's failing.
