Trying to create integration tests for GraphQL

[wesleyreaca5dd]

Hey,

I'm trying to create integration tests for some GraphQL endpoints.

To test the configuration, I created this very simple test case, but even this simple query is not working. 

    public function testProducts() {
        $query = <<<QUERY
{
  products(filter: {sku: {eq: "outfit"}}) {
    items {
      name
      sku
      url_key
      stock_status
    }
  }
}
QUERY;

        $response = $this->graphQlRequest->send($query);
        $responseData = $this->json->unserialize($response->getContent());

        $this->assertArrayNotHasKey('errors', $responseData);
    }

 The error im getting is:

Field "sku" is not defined by type ProductAttributeFilterInput.

If i execute the same query outside of the integration test everything works fine.

Any idea how i can get this working?
