Error: Call to undefined method get() in PHPUnit Symfony-CodePudding

I am trying to execute my first unit test with PHPUnit 9.0.0 and Symfony 5.1.8. This test must to pass if the HTTP response is 200.

<?php declare(strict_types=1);

namespace Tests\Infrastructure\Api\Controller;

use PHPUnit\Framework\TestCase;

class ControllerTests extends TestCase
{
    /** @test */
     public function route(): void
    {
        $response = $this->get('/');

        $response->assertStatus(200);
    
    }

}

I obtain the error:

There was 1 error:

Tests\Infrastructure\Api\Controller\SupplierControllerTests::route Error: Call to undefined method Tests\Infrastructure\Api\Controller\SupplierControllerTests::get()

I thought the Get method was a default method, imported by PHPUnit\Framework\TestCase, but it do not look that.

Have I to add a Get method into my class ControllerTests? How can i develop it to test the HTTP response?

Thanks in advance

CodePudding user response：

You need to extend the WebTestCase provided by Symfony, not the default TestCase provided by PHPUnit.

Here is an example for a similar test you are trying to write:

namespace App\Tests\Controller;

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;

class PostControllerTest extends WebTestCase
{
    public function testShowPost()
    {
        $client = static::createClient();

        $client->request('GET', '/post/hello-world');

        $this->assertEquals(200, $client->getResponse()->getStatusCode());
    }
}
