    grunt.loadNpmTasks('grunt-contrib-jasmine');
    grunt.loadNpmTasks('grunt-contrib-watch');

    grunt.registerTask('test', ['jasmine:all']);
    grunt.registerTask('coverage', ['jasmine:istanbul']);
    grunt.registerTask('default', ['watch']);

};

awesome!

how to mention these files are not to test... Suggest some idea.
