Call to undefined method App\Tests\E2eTest::assertPageTitleContains()

[antoine1003]

Hi, I am developing a website without any framework and I want to integrate some test using panther.

Infos

My folder structure :

myproject/
├── src/
│   ├── myprojectrootfile-1.php
│   ├── ...
├── Test/
│   ├── E2eTest.php
├── vendor/
├── composer.json
├── composer.lock
├── phpunit.xml.dist

My composer.json

{
    "require-dev": {
        "phpunit/phpunit": "9",
        "symfony/panther": "^0.7.1"
    }
}

My phpunit.xml.dist :

<phpunit>
<extensions>
	<extension class="Symfony\Component\Panther\ServerExtension" />
</extensions>
<php>
	<server name="KERNEL_DIR" value="./Tests/App" />
	<server name="PANTHER_WEB_SERVER_DIR" value="./src/" />
</php>
</phpunit>

My E2eTest.php :

<?php

namespace App\Tests;

use Symfony\Component\Panther\PantherTestCase;

class E2eTest extends PantherTestCase
{
    public function testMyApp(): void
    {
        $client = static::createPantherClient(); // Your app is automatically started using the built-in web server
        $client->request('GET', '/view/main.php');

        // Use any PHPUnit assertion, including the ones provided by Symfony
        $this->assertPageTitleContains('My Title');
        $this->assertSelectorTextContains('#main', 'My body');
    }
}

Problem

When I run .\vendor\bin\phpunit .\Tests\E2eTest.php I have an error :

1. App\Tests\E2eTest::testMyApp Error: Call to undefined method App\Tests\E2eTest::assertPageTitleContains()

I don't understand why.

Thanks for your help
