Test api returns 201 instead 200 - laravel

Question

I do not understand what happens on an API test (laravel 8).
This call (a very simple put) returns a response 200 , using postman.
The same test using phpunit, returns 201 :
public function testPutOrganizationOk()
{
$organization = Organization::factory()->create();
$superAdmin = User::factory()->create([
'organization_id' => $organization->id,
'role_id' => 'SUPERADMIN'
]);
Sanctum::actingAs($superAdmin);
$organizationToModify = [
'name' => 'mon organization moif',
'contact' => 'contact name modif',
'comment' => 'comment comment comment modif',
'ads_max' => 12345,
'state_id' => 'VALIDATED'
];
$response = $this->putJson($this->getUrl() . '/organizations/' . $organization->id, $organizationToModify);
$response->assertStatus(200);
}
The error is :
Tests\Feature\OrganizationTest::testPutOrganizationOk Expected status code 200 but received 201. Failed asserting that 200 is
identical to 201.
I tried a lot of things , without success. I really do not understand what happens. Any suggestions will be appreciated. Thanks.
EDIT :my controller
public function update(StoreOrganizationRequest $request, Organization $organization)
{
$this->authorize('update', Organization::class);
$organizationUpdated = $this->organizationRepository->updateOrganization($organization, $request->only(['name', 'contact', 'comment', 'ads_max', 'state_id']));
return new OrganizationResource($organizationUpdated);
}
EDIT 7 hours later ;-)
When I replace , in the controller, the return of the resource by a return of a simple json, then I have the same behaviour between postman and phpunit . The api call receives a 200 for the update.
Strange, it means that the problem is around the resource ?
Why a different behavior between postman and phpunit ? Who is right : postman or phpunit ?

Answer 1

The http code 201, it mean created success.
see here developer.mozilla.org
and you able to customize the header code by:
return Response::json(new OrganizationResource($organizationUpdated), 200);

Answer 2

201 Status Code says that you just create an Instance, and
200 Status Code says that already existing Instance has been update
The PUT method requests that the enclosed entity be stored under the supplied Request-URI. If the Request-URI refers to an already existing resource, the enclosed entity SHOULD be considered as a modified version of the one residing on the origin server. If the Request-URI does not point to an existing resource, and that URI is capable of being defined as a new resource by the requesting user agent, the origin server can create the resource with that URI."
I might be wrong but seems like you have created the instance first and trying to modifying it then

Answer 3

Finally, I give up!
I will write the response with a status code like that:
return (new OrganizationResource($organization))->response()->setStatusCode(200);
instead of:
return new OrganizationResource($organization);
it's longer to write, but at least my tests are OK.
