}

public function additionWithNonNegativeNumbersProvider()
{
    return [
        [0, 1, 1],
        [1, 0, 1],
        [1, 1, 3]

ArgumentCountError : Too few arguments to function controllerTests::testAdd(), 0 passed in phar://C:/xampp/htdocs/2019-1-qa-grupo1/myss/Tests/phpunit-8.1.2.phar/phpunit/Framework/TestCase.php on line 1172 and exactly 3 …
