Laravel 5 Reseeding the Database for Unit Testing Between Tests - database

Question

I start with a seeded database and am trying to reseed the database between unit tests in Laravel 5. In Laravel 4 I understand you could simply use Illuminate\Support\Facades\Artisan and run the commands
Artisan::call('migrate');
Artisan::call('db:seed');
or you supposedly could do:
$this->seed('DatabaseSeeder');
before every test. In Laravel 5 this appears to have been replaced by
use DatabaseMigrations;
or
use DatabaseTransactions;
I have tried using these and have managed to get the tests to migrate the database; however, it doesn't actually reseed the data in the tables. I have read through several forums complaining about this and have tried several different approaches calling these from the TestCase and inside every Test...adding the
$this->beforeApplicationDestroyed(function () {
Artisan::call('migrate');
Artisan::call('migrate:reset');
Artisan::call('db:seed');
DB::disconnect();
});
to the TestCase.php tearDown()...
I have also tried adding
$this->createApplication();
to a method called in every test from TestCase.php
Sometimes it just wipes my tables out completely. Nothing I am finding on Laravel's site or in blogs seems to work. Part of it is probably because I'm probably trying Laravel 4 methods in Laravel 5. Is there any way to do this in Laravel 5?
My code for the testcase.php looks like:
<?php
use Illuminate\Support\Facades\Artisan as Artisan;
class TestCase extends Illuminate\Foundation\Testing\TestCase{
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;
protected $baseUrl = 'http://localhost';
public function initializeTests(){
$this->createApplication();
Artisan::call('migrate');
$this->artisan('migrate');
Artisan::call('db:seed');
$this->artisan('db:seed');
$this->seed('DatabaseSeeder');
$this->session(['test' => 'session']);
$this->seed('DatabaseSeeder');
}
public function tearDown()
{
Mockery::close();
Artisan::call('migrate:reset');
$this->artisan('migrate:reset');
Artisan::call('migrate:rollback');
$this->artisan('migrate:rollback');
Artisan::call('migrate');
$this->artisan('migrate');
Artisan::call('db:seed');
$this->artisan('db:seed');
$this->seed('DatabaseSeeder');
DB::disconnect();
foreach (\DB::getConnections() as $connection) {
$connection->disconnect();
}
$this->beforeApplicationDestroyed(function () {
Artisan::call('migrate:reset');
$this->artisan('migrate:reset');
Artisan::call('migrate:rollback');
$this->artisan('migrate:rollback');
Artisan::call('migrate');
$this->artisan('migrate');
Artisan::call('db:seed');
$this->artisan('db:seed');
$this->seed('DatabaseSeeder');
DB::disconnect();
foreach (\DB::getConnections() as $connection) {
$connection->disconnect();
}
});
$this->flushSession();
parent::tearDown();
}
public function getConnection()
{
$Connection = mysqli_connect($GLOBALS['DB_DSN'], $GLOBALS['DB_USERNAME'], $GLOBALS['DB_PASSWORD'], $GLOBALS['DB_DATABASE']);
$this->createDefaultDBConnection();
return $this->Connection;
}
public function createApplication()
{
$app = require __DIR__.'/../bootstrap/app.php';
$app->make(Illuminate\Contracts\Console\Kernel::class)->bootstrap();
return $app;
}
/**
* Magic helper method to make running requests simpler.
*
* #param $method
* #param $args
* #return \Illuminate\Http\Response
*/
public function __call($method, $args)
{
if (in_array($method, ['get', 'post', 'put', 'patch', 'delete']))
{
return $this->call($method, $args[0]);
}
throw new BadMethodCallException;
}
/**
* Create a mock of a class as well as an instance.
*
* #param $class
* #return \Mockery\MockInterface
*/
public function mock($class)
{
$mock = Mockery::mock($class);
$this->app->instance($class, $mock);
return $mock;
}
}
My Test looks something like
<?php
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;
use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\Artisan;
class CustomerRegistrationControllerTest extends TestCase
{
use DatabaseMigrations;
protected static $db_inited = false;
protected static function initDB()
{
echo "\n---Customer Registration Controller Tests---\n"; // proof it only runs once per test TestCase class
Artisan::call('migrate');
Artisan::call('db:seed');
}
public function setUp()
{
parent::setUp();
if (!static::$db_inited) {
static::$db_inited = true;
static::initDB();
}
// $this->app->refreshApplication();
$this->artisan('migrate:refresh');
$this->seed();
$this->seed('DatabaseSeeder');
$this->initializeTests();
);
}
public function testSomething()
{
$this->Mock
->shouldReceive('destroy')
->with('1')
->andReturn();
$this->RegistrationController->postRegistration();
// $this->assertResponseStatus(200);
}
}

Answer 1

Just run this:
$this->artisan('migrate:refresh', [
'--seed' => '1'
]);
To avoid changes to the database persisting between tests add use DatabaseTransactions to your tests that hit the database.

Answer 2

Why not create your own command like db:reset.
This command either truncate all your tables or drop/create schema and then migrate.
In your test you then use: $this->call('db:reset') in between your tests
