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: drop_mv.rs
    path of file: ./repos/risingwave/src/frontend/src/handler
    
    the code of the file until where you have to start completion: // Copyright 2024 RisingWave Labs

    async fn test_drop_mv_handler() {
        let sql_create_table = "create table t (v1 smallint);";
        let sql_create_mv = "create materialized view mv as select v1 from t;";
        let sql_drop_mv = "drop materialized view mv;";
        let frontend = LocalFrontend::new(Default::default()).await;
        frontend.run_sql(sql_create_table).await.unwrap();
        frontend.run_sql(sql_create_mv).await.unwrap();
        frontend.run_sql(sql_drop_mv).await.unwrap();

        let session = frontend.session_ref();
        let catalog_reader = session.env().catalog_reader().read_guard();
        let schema_path = SchemaPath::Name(DEFAULT_SCHEMA_NAME);

        let table = catalog_reader.get_table_by_name(DEFAULT_DATABASE_NAME, schema_path, "mv");
        assert!(table.is_err());
    }
