如何在PHPUnit中解决这个问题,它要求我在PHPUnit中设置KERNEL\u DIR。xml?

这是我的护照。xml文件

<?xml version="1.0" encoding="UTF-8"?>
<phpunit
        colors="true"
        convertErrorsToExceptions="true"
        convertNoticesToExceptions="true"
        convertWarningsToExceptions="true"
        stopOnFailure="true"
        strict="true"
        bootstrap="./vendor/autoload.php">
    <testsuites>
        <php>
            <server name="KERNEL_DIR" value="app" />
            <ini name="display_errors" value="true"/>
        </php>
        <testsuite name="Functional Tests">
            <directory>./tests/src/myApp/AppBundle/functional</directory>
        </testsuite>
    </testsuites>

    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./src/</directory>
        </whitelist>
    </filter>
</phpunit>

这是考试课

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class MyTest extends WebTestCase
{
    private $client;

    public function setUp()
    {
        $this->client = static::createClient();
    }

运行测试时,我在设置中的行中得到:

在phpunit中设置KERNEL\u DIR。xml依据 https://symfony.com/doc/current/book/testing.html#your-first-functional-test 或者重写WebTestCase::createKernel()方法
