        // This ensures that the tests get run under the correct environment, using the correct database, and
        // that they work as expected. Trying to run tests with no ENV set will throw an error to do with `client`.

        //
        // Ghost's GitHub repository contains the un-built source code for Ghost. If you're looking for the already
        // built release zips, you can get these from the [release page](https://github.com/TryGhost/Ghost/releases) on
        // GitHub or from https://ghost.org/download. These zip files are created using the [grunt release](#release)
        // task.
        //
        // If you want to work on Ghost core, or you want to use the source files from GitHub, then you have to build
        // the Ghost assets in order to make them work.
        //
        // There are a number of grunt tasks available to help with this. Firstly after fetching an updated version of
        // the Ghost codebase, after running `npm install`, you will need to run [grunt init](#init%20assets).
        //
        // For production blogs you will need to run [grunt prod](#production%20assets).
        //
        // For updating assets during development, the tasks [grunt](#default%20asset%20build) and
        // [grunt dev](#live%20reload) are available.

        // ### Init assets
        // `grunt init` - will run an initial asset build for you
        //
        // Grunt init runs `npm install && bower install` inside `core/client` as well as the standard asset build
        // tasks which occur when you run just `grunt`. This fetches the latest client-side dependencies.
        //
        // This task is very important, and should always be run when fetching down an updated code base just after
        // running `npm install`.
        //
        // `bower` does have some quirks, such as not running as root. If you have problems please try running

        // This works hand-in-hand with the [livereload](http://livereload.com/) chrome extension.
        //
        // `grunt dev` manages starting an express server and restarting the server whenever core files change (which
        // require a server restart for the changes to take effect) and also manage reloading the browser whenever
