如何从PHPUnit Test setUp运行Laravel数据库播种机？

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();
    }
}

运行phpunit失败并显示错误:

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

E 1/1(100%)

时间:2.19秒,内存:12.00MB

有1个错误:

1)CourseTypesTest :: test_list_course_types ReflectionException:类TestDatabaseSeeder不存在

错误!测试:1,断言:0,错误:1.

但是这个类存在:

Answer 1

从 5.8 版开始，您可以执行以下操作：

// Run the DatabaseSeeder...
$this->seed();

// Run a single seeder...
$this->seed(OrderStatusesTableSeeder::class);

看一下文档

Answer 2

该DatabaseSeeder可自行实例化,其call方法是公共的.

在CourseTypesTest课堂上你需要做的就是

(new DatabaseSeeder())->call(TestDatabaseSeeder::class);

或者您可以使用Laravel的app助手,如下所示

app(DatabaseSeeder::class)->call(TestDatabaseSeeder::class);

Answer 3

问题是--class参数中的空格.如果仔细看看数组,最后'--class' => 'TestDatabaseSeeder '会有空间......这就是问题所在.改变它'--class' => 'TestDatabaseSeeder',它应该工作正常.
