How to Run Laravel Database Seeder from PHPUnit Test setUp?

Question

I am trying to recreate the database before each test in some PHPUnit test cases. I am using Laravel 5.3. Here is TestCase:

class CourseTypesTest extends TestCase
{
    public function setUp()
    {
        parent::setUp();
        Artisan::call('migrate');
        Artisan::call('db:seed', ['--class' => 'TestDatabaseSeeder ', '--database' => 'testing']);
    }

    /**
     * A basic functional test example.
     *
     * @return void
     */
    public function test_list_course_types()
    {
        $httpRequest = $this->json('GET', '/api/course-types');
        $httpRequest->assertResponseOk();
        $httpRequest->seeJson();

    }

    public function tearDown()
    {
        Artisan::call('migrate:reset');
        parent::tearDown();
    }
}

Running phpunit fails with error:

$ phpunit PHPUnit 5.7.5 by Sebastian Bergmann and contributors.

The problem is empty space in your --class argument. If you take close look at array '--class' => 'TestDatabaseSeeder ' there is space in the end ... this is the problem. Change it to '--class' => 'TestDatabaseSeeder' and it should work fine.
