    ### Test Configuration
    
    We don't need much configuration to run unit tests. 
    We don't need the loaders and plugins that we declared for our development and production builds.
    We probably don't need to load and process `css` files for unit tests and doing so would slow us down;
    we'll use the `null` loader for all CSS.
    
    We could merge our test configuration into the `webpack.common` configuration and override the parts we don't want or need.
    But it might be simpler to start over with a completely fresh configuration.

    Here's our karma configuration:

    We're telling Karma to use webpack to run the tests. 
    
    We don't precompile our TypeScript; Webpack transpiles our Typescript files on the fly, in memory, and feeds the emitted JS directly to Karma.
    There are no temporary files on disk.
    
    The `karma-test-shim` tells Karma what files to pre-load and 
    primes the Angular test framework with test versions of the providers that every app expects to be pre-loaded.

negative.code:   We've learned just enough Webpack to configurate development, test and production builds 
    for a small Angular application.
    
    Nous venons juste d'apprendre de Webpack comment configurer les builds de développement, de test et de production.
