Laravel DB class not found

Question

I am just trying to config my Laravel new project, I am working on xampp localhost. When I tried to run my first db insert this error appears "Fatal error: Class 'DB' not found in C:\\xampp\\htdocs\\boh\\index.php on line 48"

here is my database.php

    'mysql' => [
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'boh',
    'username'  => 'root',
    'password'  => '',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
    'strict'    => false,
],

and here the short script:

 <?php
    DB::select('INSERT INTO `boh` VALUES name="John"');
    ?>

Here is an example of how you to set up a basic controller, route and your SQL query.

app/HTTP/Controllers/TestController.php

<?php namespace App\Http\Controllers;

use DB;

class TestController extends Controller {

    public function getInsert()
    {
        DB::table('boh')->insert(
            ['name' => 'john']
        );
    }
}

app/HTTP/routes.php

<?php

Route::get('insert-test', 'TestController@getInsert');

Navigate to yourdomain.com/insert-test
