Netbeans не запускает тесты PHPUnit

Я использую PHP7.1 в последней версии Netbeans и пытаюсь запустить вместе с ним PHPUnit 6.5. Когда я запускаю тесты в Netbeans, они не выполняются, и в окне вывода отображается следующая трассировка стека:

"C:\bin\phpunit.bat" "--colors" "--log-junit" "C:\Users\rwinkler\AppData\Local\Temp\nb-phpunit-log.xml" "C:\bin\phpunit.phar"

Fatal error: Uncaught PHPUnit\Runner\Exception: Class 'C:\bin\phpunit' could not be found in 'C:\bin\phpunit.phar'. in phar://C:/bin/phpunit.phar/phpunit/Runner/StandardTestSuiteLoader.php:102

Done.

Мой тест - это образец теста, который я взял из учебника:

<?php
require_once 'PHPUnit/Autoload.php';
declare(strict_types=1);

use PHPUnit\Framework\TestCase;

final class EmailTest extends TestCase
{
    public function testCanBeCreatedFromValidEmailAddress(): void
    {
        $this->assertInstanceOf(
            Email::class,
            Email::fromString('[email protected]')
        );
    }

    public function testCannotBeCreatedFromInvalidEmailAddress(): void
    {
        $this->expectException(InvalidArgumentException::class);

        Email::fromString('invalid');
    }

    public function testCanBeUsedAsString(): void
    {
        $this->assertEquals(
            '[email protected]',
            Email::fromString('[email protected]')
        );
    }
}
