Test execution errrors on PHP 8.5 when data provider provides `INF` or `NAN` as value

[bkdotcom]

Q	A
PHPUnit version	9.6.29
PHP version	8.5.1-dev
Installation Method	Composer

Summary

if a @dataProvider contains INF:
execution halts with the error: "The float INF is not representable as an int, cast occurred"

if a @dataProvider contains NAN
execution halts with the error: "unexpected NAN value was coerced to string"

class InfTest extends TestCaseBase
{
    /**
     * @dataProvider dataProvider
     */
    public function testStuff($value)
    {
        self::assertTrue(true);
    }

    public function dataProvider()
    {
        return [
            'inf' => [INF],
            'nan' => [NAN],
        ];
    }
}

I cannot reproduce this with PHPUnit 8.5, PHPUnit 9.6, PHPUnit 10.5, PHPUnit 11.5, PHPUnit 12.4, PHPUnit 12.5, or PHPUnit 13.0.

Are you sure that you use PHPUnit 9.6.29 with up-to-date dependencies? You need the latest version of sebastian/exporter, for example.

fresh composer install

vendor/bin/phpunit -> results in the error
vendor/bin/phpunit tests/BrokenTest.php -> no error

still trying to track down where the error is thrown

Please share the output of composer info.

The error is via:
vendor/sebastian/exporter/src/Exporter.php(245)

        if (is_float($value)) {
            $precisionBackup = ini_get('precision');

            ini_set('precision', '-1');

            try {
                $valueStr = @(string) $value;               //      <!--  THE CULPRIT LINE (FOR NAN)

                if ((string) @(int) $value === $valueStr) {    //         <!--  THE CULPRIT LINE (FOR INF)
                    return $valueStr . '.0';
                }

                return $valueStr;
            } finally {
                ini_set('precision', $precisionBackup);
            }
        }

It appears master has the same logic
