Tools for non regression testing on REST API? - symfony

Question

I have developed a project with a symfony server as backend and a mobile application as frontend.
I am unemployed but I hope to start my own business :)
What tool(s) should I use for non regression testing ?
Thank you for your help!

I suppose you don't use API Platform. It provides the ApiTestCase that provides several assertions to test JSON responses :
class BooksTest extends ApiTestCase
{
// This trait provided by AliceBundle will take care of refreshing the database content to a known state before each test
use RefreshDatabaseTrait;
public function testGetCollection(): void
{
// The client implements Symfony HttpClient's `HttpClientInterface`, and the response `ResponseInterface`
$response = static::createClient()->request('GET', '/books');
$this->assertResponseIsSuccessful();
// Asserts that the returned content type is JSON-LD (the default)
$this->assertResponseHeaderSame('content-type', 'application/ld+json; charset=utf-8');
// Asserts that the returned JSON is a superset of this one
$this->assertJsonContains([
'#context' => '/contexts/Book',
'#id' => '/books',
'#type' => 'hydra:Collection',
'hydra:totalItems' => 100,
'hydra:view' => [
'#id' => '/books?page=1',
'#type' => 'hydra:PartialCollectionView',
'hydra:first' => '/books?page=1',
'hydra:last' => '/books?page=4',
'hydra:next' => '/books?page=2',
],
]);
As you can see, in this example, the /books endpoint of the API is tested. But you can also use the standard WebTestCase provided by Symfony to do this manually.
