  - gradle npm_test      # or ./npm test
  + npm test
   
   NOTE: The default Facebook library for testing React applications is Jest, but
   Jest is slow and classes under test had strange issues like array pushes
  
positive.code: 
  To test for blacklisted modules (listed in package.json):
  
   gradle npm_run_check-blacklisted
  
  To test for latest versions of build packages (listed in package.json):
  
   gradle npm_outdated
  
  [[build]]
  === Build
  
  http://gulpjs.com/[Gulp] is the build system used for the frontend. It can also
  be accessed via the gradle build.
  
  To create a minified and compiled version of all assets (including CSS
  preprocessors such as less and sass, and compilation of typescript files), run:
  
   gradle gulp_build --release
  
  Or to produce non-minified CSS and JS files in the build:
  
   gradle gulp_build
  
  To deploy documentation to GitHub pages (use `--production` or `--staging` as
  necessary, see the build file):
  
   gradle gulp_deploy   # or, `gulp deploy --production`
  
  Specific gulp tasks can be executed e.g.:
  
   gradle gulp_lint
  
  To watch source files for changes and automatically update the compiled build
  (to see changes immediately in Play, for example), leave the gulp serve task
  running:
  
   gradle gulp_serve
  
  Gulp can also be executed directly instead of via gradle, which has the
  advantage of colored output, as well as :
  
   node_modules/.bin/gulp ...      # Or ./gulp
  
  When running gulp directly, specify the task before other arguments: e.g.
  
    ./gulp build --verbose

negative.code: 
  To execute:
  
   npm run-script testb
  
  (testb stands for "test in browser")
  
  ==== Browser Sync
  
  Running the application via `gulp sync` will run a
  http://www.browsersync.io/[BrowserSync] session. This provides live reload
  functionality in the browser when changes are made to server-side code. It will
  also synchronize multiple browsers (clicks, scrolling, and so forth), which is
  useful for multi-browser verification.
  
  WARNING: Current BrowserSync does not support websocket connections. Therefore
  `gulp sync` is not yet useful.
