如何在phpunit中捕獲異常

Question

我正在進行功能測試以檢查特定用戶無法更新資源，在這種情況下，API 會以 404 錯誤重播。 這是測試：

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');

當我運行這個測試時，我得到 404 響應，這很好：

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)

所以測試通過了，但控制台仍然顯示異常。 所以我在客戶端調用之前添加了這個：

$this->expectException(NotFoundHttpException::class);

這是結果：

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.

正如你所看到的，異常被拋出，但同時我收到一個錯誤，說它不是。 知道如何抓住這個嗎？

確保首先調用以下方法：

$client->catchExceptions(false);

例如：

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');
}
