MockGraphqlServer stands for the GraphQL server in the tests of your application: it answers the queries with the responses you queue, in order, and records them. It replaces the HTTP client of the bundle, so the queries still go through the GraphQL client, its error handling and the profiler.

yaml

# config/packages/graphql_orm.yaml
when@test:
    graphql_orm:
        http_client: GraphqlOrm\Test\MockGraphqlServer

The bundle then registers the server as a public service, fetched by the tests from the container:

php

use GraphqlOrm\Test\MockGraphqlServer;
use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;

final class TaskServiceTest extends KernelTestCase
{
    #[Test]
    public function itListsTheOpenTasks(): void
    {
        $server = self::getContainer()->get(MockGraphqlServer::class);
        $server->respond(['tasks' => ['items' => [['id' => 1, 'title' => 'Write the docs']]]]);

        $tasks = self::getContainer()->get(TaskService::class)->openTasks();

        self::assertSame('Write the docs', $tasks[0]->title);
        self::assertCount(1, $server->requests());
        self::assertStringContainsString('done: { eq: false }', $server->requests()[0]->query);
    }
}

Method	Queues
`respond($data)`	a response holding this `data`, keyed by root field
`respondWithErrors($errors, $data)`	GraphQL errors, with the partial data given if any
`respondWithHttpStatus($statusCode)`	an HTTP error, e.g. `503`

requests() returns the requests received, each with its query and its variables. A query sent once every queued response is used fails with a LogicException showing it.

The responses are written in the shape of your API: items for Data API Builder, edges/node for Relay... With variables or schema_validation enabled, the bundle also sends introspection queries: keep them disabled in the tests, or queue their responses first.
