如何从 PHPUnit 测试设置运行 Laravel Database Seeder？

Question

我试图在一些 PHPUnit 测试用例中的每次测试之前重新创建数据库。我正在使用 Laravel 5.3。这是测试用例：

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();
    }
}

运行

phpunit

失败并出现错误：

$ phpunit PHPUnit 5.7.5 由 Sebastian Bergmann 和贡献者提供。
