【Laravel】テストデータの登録をTraitで共通化する方法！

<?php

namespace Tests\Traits;

trait SeedTestData
{
    public function seedTestData()
    {
        \DB::table('your_table_name')->insert([
            'hoge' => '1',
        ]);
    }
}

<?php

namespace Tests\Feature;

use Illuminate\Foundation\Testing\RefreshDatabase;
use Tests\TestCase;
use Tests\Traits\SeedTestData;

class SampleTest extends TestCase
{
    use RefreshDatabase, SeedTestData;

    public function testSuccessfulResponse()
    {
        $this->seedTestData();

        $response = $this->get('/api');

        $response->assertOk();
    }
}
