        // ## Testing

        // Ghost has an extensive set of test suites. The following section documents the various types of tests
        // and how to run them.
        //
        // TLDR; run `grunt validate`

        // #### Set Test Env *(Utility Task)*
        // Set the NODE_ENV to 'testing' unless the environment is already set to TRAVIS.
        // 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`.
        grunt.registerTask('setTestEnv',
            'Use "testing" Ghost config; unless we are running on travis (then show queries for debugging)',

                cfg.express.test.options.node_env = process.env.NODE_ENV;
            });

        // #### Load Config *(Utility Task)*
        // Make sure that we have a `config.js` file when running tests
        // Ghost requires a `config.js` file to specify the database settings etc. Ghost comes with an example file:
        // `config.example.js` which is copied and renamed to `config.js` by the bootstrap process
        grunt.registerTask('loadConfig', function () {
            var done = this.async();
            bootstrap().then(function () {

        // ### Validate
        // **Main testing task**
        //
        // `grunt validate` will lint and test your local Ghost codebase.
        //
        // `grunt validate` is one of the most important and useful grunt tasks that we have available to use. It
        // manages the setup and running of jshint as well as the 4 test suites. See the individual sub tasks below
        // for details of each of the test suites.

        // `grunt test-unit` will run just the unit tests
        //
        // Provided you already have a `config.js` file, you can run individual sections from
        // [mochacli](#grunt-mocha-cli) by running:
        //
        // `NODE_ENV=testing grunt mochacli:section`
        //
        // If you need to run an individual unit test file, you can do so, providing you have mocha installed globally by
        // using a command in the form:
        //
        // `NODE_ENV=testing mocha --timeout=15000 --ui=bdd --reporter=spec core/test/unit/config_spec.js`
        //
        // Unit tests are run with [mocha](http://visionmedia.github.io/mocha/) using
        // [should](https://github.com/visionmedia/should.js) to describe the tests in a highly readable style.
        // Unit tests do **not** touch the database.
        // A coverage report can be generated for these tests using the `grunt test-coverage` task.

        // ### Integration tests *(sub task)*
        // `grunt test-integration` will run just the integration tests
        //
        // Provided you already have a `config.js` file, you can run just the model integration tests by running:
        //
        // `NODE_ENV=testing grunt mochacli:model`
        //
        // Or just the api integration tests by running:
        //
        // `NODE_ENV=testing grunt mochacli:api`
        //
        // Integration tests are run with [mocha](http://visionmedia.github.io/mocha/) using
        // [should](https://github.com/visionmedia/should.js) to describe the tests in a highly readable style.
        // Integration tests are different to the unit tests because they make requests to the database.
        //
        // Their purpose is to test that both the api and models behave as expected when the database layer is involved.
        // These tests are run against sqlite3, mysql and pg on travis and ensure that differences between the databases
        // don't cause bugs. At present, pg often fails and is not officially supported.
        //
        // A coverage report can be generated for these tests using the `grunt test-coverage` task.

        // ### Route tests *(sub task)*
        // `grunt test-routes` will run just the route tests
        //
        // If you need to run an individual route test file, you can do so, providing you have a `config.js` file and
        // mocha installed globally by using a command in the form:
        //
        // `NODE_ENV=testing mocha --timeout=15000 --ui=bdd --reporter=spec core/test/functional/routes/admin_test.js`
        //
        // Route tests are run with [mocha](http://visionmedia.github.io/mocha/) using
        // [should](https://github.com/visionmedia/should.js) and [supertest](https://github.com/visionmedia/supertest)
        // to describe and create the tests.
        //
        // Supertest enables us to describe requests that we want to make, and also describe the response we expect to
        // receive back. It works directly with express, so we don't have to run a server to run the tests.
        //
        // The purpose of the route tests is to ensure that all of the routes (pages, and API requests) in Ghost
        // are working as expected, including checking the headers and status codes received. It is very easy and
        // quick to test many permutations of routes / urls in the system.
        grunt.registerTask('test-routes', 'Run functional route tests (mocha)',

        // ### Functional tests *(sub task)*
        // `grunt test-functional` will run just the functional tests
        //
        // You can use the `--target` argument to run any individual test file, or the admin or frontend tests:
        //
        // `grunt test-functional --target=admin/editor_test.js` - run just the editor tests
        //
        // `grunt test-functional --target=admin/` - run all of the tests in the admin directory
        //
        // Functional tests are run with [phantom.js](http://phantomjs.org/) and defined using the testing api from
        // [casper.js](http://docs.casperjs.org/en/latest/testing.html).
        //
        // An express server is started with the testing environment set, and then a headless phantom.js browser is
        // used to make requests to that server. The Casper.js API then allows us to describe the elements and
        // interactions we expect to appear on the page.
        //
        // The purpose of the functional tests is to ensure that Ghost is working as is expected from a user perspective
        // including buttons and other important interactions in the admin UI.
        grunt.registerTask('test-functional', 'Run functional interface tests (CasperJS)',
            ['clean:test', 'setTestEnv', 'loadConfig', 'copy:dev', 'express:test', 'spawnCasperJS', 'express:test:stop']
        );

        // ### Coverage
        // `grunt test-coverage` will generate a report for the Unit and Integration Tests.
        //
        // This is not currently done as part of CI or any build, but is a tool we have available to keep an eye on how
        // well the unit and integration tests are covering the code base.
        // Ghost does not have a minimum coverage level - we're more interested in ensuring important and useful areas
        // of the codebase are covered, than that the whole codebase is covered to a particular level.
        //
        // Key areas for coverage are: helpers and theme elements, apps / GDK, the api and model layers.

        // ## Building assets
        //
        // 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.
        //

        // #### Master Warning *(Utility Task)*
        // Warns git users not ot use the `master` branch in production.
        // `master` is an unstable branch and shouldn't be used in production as you run the risk of ending up with a
        // database in an unrecoverable state. Instead there is a branch called `stable` which is the equivalent of the
        // release zip for git users.

        // ### Init assets
        // `grunt init` - will run an initial asset build for you
        //
        // Grunt init runs `bower install` as well as the standard asset build tasks which occur when you run just
        // `grunt`. This fetches the latest client side dependencies, and moves them into their proper homes.
        //
        // This task is very important, and should always be run and 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
        // frontend code changes.
