use PHPUnit\Framework\TestCase;
use PHPUnit\Framework\Attributes\DataProvider;

class SonarTest extends TestCase
{
    public static function provider_testAssertion(): iterable
    {
        return [
            [
                'callback' => function () {
                    // This is not recognized by SonarQube.
                    $this->assertTrue(true);
                },
            ],
        ];
    }

    #[DataProvider('provider_testAssertion')]
    public function testAssertion(callable $callback): void
    {
        $callback->call($this);
    }
}

Hey @decix-msauer ,

thank you for reporting this.

I confirm this is a false-positive and did create an internal ticket to address this.

Best,
Karim.
