This is a syntax highlighting plugin for the Jasmine JavaScript testing framework. I extracted most of this from thomd's VIM-Jasmine plugin which is wonderful, but overkill for what I was looking for. I made a few modifications to suit my preferences.

This plugin contributes to vim-polyglot language pack.

Add:

Bundle 'glanotte/vim-jasmine'

To your .vimrc and run BundleInstall from within vim or vim +BundleInstall +qall from the command line

cd ~/.vim/bundle
git clone https://github.com/glanotte/vim-jasmine.git

By default this syntax is used with all *_spec.js and *Spec.js files. If you don't follow this norm use something like:

autocmd BufReadPost,BufNewFile *_foo.js set filetype=jasmine.javascript syntax=jasmine

In your ~/.vimrc

This assumes that you are using some other javascript plugin for syntax highlighting and it attaches itself onto the JavaScriptAll cluster.
