Laravel,Graghql,phpunitでテストする。

/tests/TestCase.phpに下記を追加

tests/TestCase.php

<?php

namespace Tests;

use Nuwave\Lighthouse\Testing\MakesGraphQLRequests; // 追加
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;
    use MakesGraphQLRequests; // 追加
}

phpunit.xmlに下記を追加

phpunit.xml

    <testsuites>
        <testsuite name="Unit">
            <directory suffix="Test.php">./tests/Unit</directory>
        </testsuite>
        <testsuite name="Feature">
            <directory suffix="Test.php">./tests/Feature</directory>
        </testsuite>

       <!--  下記の三行を追加 -->
        <testsuite name="Graghql">
            <directory suffix="Test.php">./tests/Graghql</directory>
        </testsuite>
    </testsuites>

上記でtests/Graghqlの中を見るようになります。

tests/Graghql/UserTest.php

    <?php

namespace Tests\Unit;

use Tests\TestCase;
use App\Models\User;

class UserTest extends TestCase
{
    /**
     * A basic unit test example.
     *
     * @return void
     */
    public function test_loginUser()
    {
        $res = $this->graphQL(/** @lang GraphQL */ '
            query(
                $user_name: String!
                $password: String!
                ){
                loginUser(
                    user_name: $user_name
                    password: $password
                ) {
                    result
                }
            }
          ', [
                'user_name' => 'テストユーザー',
                'password' => 'testpassword'
              ]
          );
        $res->assertStatus(200);
    }
}
