How to catch an exception in phpunit - php

Question

I am working on a functional test to check a specific user can't update a resource, in this case the API replays with a 404 error. This is the test:
static::createClient()->request(
'PUT',
'/api/bookings/' . $bookingIdToUpdate,
[
'auth_bearer' => $token,
'json' => [
'requestedBy' => 'a new value for this field',
],
]
);
self::assertResponseStatusCodeSame(Response::HTTP_NOT_FOUND, 'This user is not expected to be able to update this booking');
when I run this test, I get a 404 response, which is fine:
Testing App\Tests\Integration\BookingTest
2020-01-21T15:00:07+00:00 [error] Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "Not Found" at /var/www/html/vendor/api-platform/core/src/EventListener/ReadListener.php line 116
. 1 / 1 (100%)
Time: 38.89 seconds, Memory: 42.50 MB
OK (1 test, 1 assertion)
so the test is passing but the console is still displaying the exception. so I added this just before client call:
$this->expectException(NotFoundHttpException::class);
and this is the result:
Testing App\Tests\Integration\BookingTest
2020-01-21T15:15:05+00:00 [error] Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "Not Found" at /var/www/html/vendor/api-platform/core/src/EventListener/ReadListener.php line 116
F 1 / 1 (100%)
Time: 41.39 seconds, Memory: 42.50 MB
There was 1 failure:
1) App\Tests\Integration\BookingTest::testUserCantUpdateABookingFromAnotherOrganisation
Failed asserting that exception of type "Symfony\Component\HttpKernel\Exception\NotFoundHttpException" is thrown.
FAILURES!
Tests: 1, Assertions: 2, Failures: 1.
as you can see the exception is thrown, but at the same time I am getting an error saying it was not. Any idea how to catch this?

Ensure you call the following method first:
$client->catchExceptions(false);
For example:
public function testUserCantUpdateABookingFromAnotherOrganisation()
{
$this->expectException(NotFoundHttpException::class);
$client = static::createClient();
$client->catchExceptions(false);
$client->request('GET', '/foo/bar');
$client->request(
'PUT',
'/api/bookings/' . $bookingIdToUpdate,
[
'auth_bearer' => $token,
'json' => [
'requestedBy' => 'a new value for this field',
],
]
);
self::assertResponseStatusCodeSame(Response::HTTP_NOT_FOUND, 'This user is not expected to be able to update this booking');
}
