        $resultData = SQL::fetchAll($sql, 'BACKOFFICE', Config::get('BKDB', 'SQL'));

然后我通过命令行运行测试：

-$./vendor/bin/phpunit /home/administrador/Documentos/api-es-front-01/tests/_helpers/TestTaxInformationRepository_class.php

然后我得到以下结果：
PHPUnit 9.6.7由塞巴斯蒂安Bergmann和贡献者编写。
W 1 / 1（100%）

有1个警告：
1.警告在类“App\Tests\TestTaxInformationRepository_class”中未找到测试。
警告！

为什么找不到测试？我期待着这样的东西：
