php - 运行时异常 : Unable to guess the Kernel directory

Question

我正在使用 Symfony 3.4。突然，每当我尝试在/tests 中运行我的测试 (phpunit) 时，我都会收到以下错误:

RuntimeException : Unable to guess the Kernel directory.

我的测试类看起来像:

class PaymentCreditTest extends KernelTestCase
{
    /** @var PaymentRepository */
    public $paymentRepository;

    /**
     * {@inheritDoc}
     */
    protected function setUp()
    {
        $this->paymentRepository = self::bootKernel()->getContainer()->get('chaku.repository.payment');
    }

    public function test_canRetrieveDeadFreightNetAmount()
    {
        /** @var Payment $payment */
        $payment = $this->paymentRepository->findOneBy(['id' => 1000002]);

        // just to see payment object
        dump($payment);
    }
}

这是我的 phpunit.xml.dist 的样子:

<?xml version="1.0" encoding="UTF-8"?>

<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         bootstrap="app/autoload.php">

        <ini name="error_reporting" value="-1" />
        <server name="KERNEL_CLASS" value="AppKernel" />
        <env name="SYMFONY_DEPRECATIONS_HELPER" value="weak"/>
    </php>

    <testsuites>
        <testsuite name="Project Test Suite">
            <directory>tests</directory>
        </testsuite>
    </testsuites>

    <filter>
        <whitelist>
            <directory>src</directory>
            <exclude>
                <directory>src/*Bundle/Resources</directory>
                <directory>src/*/*Bundle/Resources</directory>
                <directory>src/*/Bundle/*Bundle/Resources</directory>
            </exclude>
        </whitelist>
    </filter>
</phpunit>

如有任何帮助，我们将不胜感激。

我想几周前我遇到了完全相同的问题，你能尝试添加 KERNEL_DIR 吗:

<php>
    <ini name="error_reporting" value="-1" />
    <server name="KERNEL_CLASS" value="AppKernel" />
    <server name="KERNEL_DIR" value="app/" />
    <env name="SYMFONY_DEPRECATIONS_HELPER" value="weak"/>
</php>
