You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: subscriptions.rs
    path of file: ./repos/graphql-client/graphql_client/tests
    
    the code of the file until where you have to start completion: use graphql_client::*;

const RESPONSE: &str = include_str!("subscription/subscription_query_response.json");

// If you uncomment this, it will not compile because the query is not valid. We need to investigate how we can make this a real test.
//
// #[derive(GraphQLQuery)]
// #[graphql(
//     schema_path = "tests/subscription/subscription_schema.graphql",
//     query_path = "tests/subscription/subscription_invalid_query.graphql"
// )]
// struct SubscriptionInvalidQuery;

#[derive(GraphQLQuery)]
#[graphql(
    schema_path = "tests/subscription/subscription_schema.graphql",
    query_path = "tests/subscription/subscription_query.graphql",
    response_derives = "Debug, PartialEq, Eq"
)]
pub struct SubscriptionQuery;

#[test]
fn s
    
fn subscriptions_work() {
    let response_data: subscription_query::ResponseData = serde_json::from_str(RESPONSE).unwrap();

    let expected = subscription_query::ResponseData {
        dog_birthdays: Some(vec![
            subscription_query::SubscriptionQueryDogBirthdays {
                name: Some("Maya".to_string()),
            },
            subscription_query::SubscriptionQueryDogBirthdays {
                name: Some("Norbert".to_string()),

                name: Some("Belka".to_string()),
            },
        ]),
    };

    assert_eq!(response_data, expected);
