DSL does not provide expected argument validation

Comienza con dsl.dsl_gql y compara su comportamiento con gql.gql usando la reproducción de la API countries de este Issue. Traza cómo se gestionan los argumentos de la consulta DSL y verifica que el filtro malformado del paso 5 genere un GraphQLError equivalente en lugar de devolver resultados sin filtrar.

Describe the bug

• When creating a query with gql.gql(), the query string is checked for invalid arguments, and raises an exception if any are found. (expected behavior)
• When creating a query with gql.dsl.dsl_gql(), the arguments are not checked, causing unexpected return values. (unexpected behavior)

I've been able to recreate this using the countries api used in the docs.

To Reproduce

Jump to step 5 to see the actual improper behavior.

1. Set up the transport/client.

   import json
   
   import gql
   from gql.transport.requests import RequestsHTTPTransport as Transport
   from gql import dsl
   
   url = "https://countries.trevorblades.com/"
   
   transport = Transport(url=url)
   client = gql.Client(transport=transport, fetch_schema_from_transport=True)
   
   # Fetch the schema (lemme know if there's a recommended approach for this).
   client.connect_sync()
   client.close_sync()
   ds = dsl.DSLSchema(client.schema)
   

2. Run a good query using strings.

   good_query_str = gql.gql(
       """
       query {
           continents (filter:{code:{eq:"AN"}}) {
               code
               name
           }
       }
       """
   )
   result = client.execute(good_query_str)
   print(json.dumps(result, indent=2))
   

   Result:

    {
    "continents": [
        {
        "code": "AN",
        "name": "Antarctica"
        }
    ]
    }
   

3. Run a bad query using strings. The only change here is using 'AN' directly as an argument to code, instead of providing the eq directive.

   bad_query_str = gql.gql(
       """
       query {
           continents (filter:{code:"AN"}) {
               code
               name
           }
       }
       """
   )
   result = client.execute(bad_query_str)
   print(json.dumps(result, indent=2))
   

   Result:

   GraphQLError: Expected value of type 'StringQueryOperatorInput', found "AN".
   
    GraphQL request:3:34
    2 |     query {
    3 |         continents (filter:{code:"AN"}) {
    |                                  ^
    4 |             code
   

4. Run a good query using DSL.

   good_query_dsl = dsl.dsl_gql(
       dsl.DSLQuery(
           ds.Query.continents(
               filter={
                   'code': {'eq': 'AN'}
               }
           ).select(
               ds.Continent.code,
               ds.Continent.name,
           )
       )
   )
   result = client.execute(good_query_dsl)
   print(json.dumps(result, indent=2))
   

   Result:

    {
    "continents": [
        {
        "code": "AN",
        "name": "Antarctica"
        }
    ]
    }
   

5. Run a bad query using DSL. Same deal, just remove the 'eq' level of filter specification. Note that the result is an unfiltered response.

   bad_query_dsl = dsl.dsl_gql(
       dsl.DSLQuery(
           ds.Query.continents(
               filter={
                   'code': 'AN'
               }
           ).select(
               ds.Continent.code,
               ds.Continent.name,
           )
       )
   )
   result = client.execute(bad_query_dsl)
   print(json.dumps(result, indent=2))
   

   Result:

    {
    "continents": [
        {
        "code": "AF",
        "name": "Africa"
        },
        {
        "code": "AN",
        "name": "Antarctica"
        },
        {
        "code": "AS",
        "name": "Asia"
        },
        {
        "code": "EU",
        "name": "Europe"
        },
        {
        "code": "NA",
        "name": "North America"
        },
        {
        "code": "OC",
        "name": "Oceania"
        },
        {
        "code": "SA",
        "name": "South America"
        }
    ]
    }
   

Expected behavior

Step 5 should raise an equivalent exception to step 3.
