[Laravel] Bootstrap file for (re)creating database before running tests

testing.php

<?php

/**
 * Bootstrap file for (re)creating database before running tests
 *
 * You only need to put this file in "bootstrap" directory of the project
 * and change "bootstrap" phpunit parameter within "phpunit.xml"
 * from "bootstrap/autoload.php" to "bootstap/testing.php"
 */

$testEnvironment = 'testing';

$config = require("app/config/{$testEnvironment}/database.php");

extract($config['connections'][$config['default']]);

$connection = new PDO("{$driver}:host={$host}", $username, $password);
$connection->query("DROP DATABASE IF EXISTS ".$database);
$connection->query("CREATE DATABASE ".$database);

require_once('app/libraries/helpers.php');

// run migrations for packages
foreach(glob('vendor/*/*', GLOB_ONLYDIR) as $package) {
    $packageName = substr($package, 7); // drop "vendor" prefix
    passthru("./artisan migrate --package={$packageName} --env={$testEnvironment}");
}
passthru('./artisan migrate --env='.$testEnvironment);

require('autoload.php'); // run laravel's original bootstap file

not working @mpyw solution, simplier same solution in setUp function call same thing Artisan::call('migrate:fresh') and it shouldn't work also
because initial solution creates database instead of modifying existing db
I created command, thats can create database by passed db name (if not exists). And then call this command every time in setUp method .

more simpler using this piece of code in setUp method

// Get the default connection name, and the database name for that connection from laravel config.
$connectionName = config('database.default');
$databaseName = config("database.connections.{$connectionName}.database");

// Set the database name to null so DB commands connect to raw mysql, not a database.
config(["database.connections.{$connectionName}.database" => null]);

// Create the db if it doesn't exist.
DB::statement("CREATE DATABASE IF NOT EXISTS " . $databaseName);

// Reset database name and purge database-less connection from cache.
config(["database.connections.{$connectionName}.database" => $databaseName ]);
DB::purge();

You can't use RefreshDatabase trait in first initial test. Because this trait (and some others) should use database that could be not exists
