Symfony ApiPlatform ApiTestCase not working - symfony

Question

I'would like to have some functionnal tests inside my ApiPlatform. When I'm inserting a User with postman, I have no probleme. But when I'am using test case I have this error message :
Uncaught PHP Exception Doctrine\ORM\ORMInvalidArgumentException: "A new entity was found through the relationship 'App\Entity\User#profile' that was not configured to cascade persist operations for entity: App\Entity\Profile#000000004079006a00000000554e4576. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example #ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'App\Entity\Profile#__toString()' to get a clue."
Here my testing code :
<?php
namespace App\Tests;
use ApiPlatform\Core\Bridge\Symfony\Bundle\Test\ApiTestCase;
use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use App\Entity\User;
class UsersTest extends ApiTestCase
{
public function testCreateBook(): void
{
$response = static::createClient()->request('POST', '/api/users', ['json' => [
'email' => '0099740915',
'username' => 'The Handmaid\'s Tale',
'password' => 'test',
'profile' => [
'firstName' => 'Test FirstName'
]
]]);
$this->assertResponseStatusCodeSame(201);
}
}
My phpunit configuration bellow :
<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="bin/.phpunit/phpunit.xsd"

<filter>
<whitelist>
<directory>src</directory>
</whitelist>
</filter>
<listeners>
<listener class="Symfony\Bridge\PhpUnit\SymfonyTestsListener" />
</listeners>
</phpunit>
I have have the following documentation from ApiPlatform : https://api-platform.com/docs/distribution/testing/
I don't know, why with a TestCase it's not working. Somebody have an idea ?
On Postman all are pefectly workling
Thanks for your help
