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: json.rs
    path of file: ./repos/prisma-engines/schema-engine/sql-migration-tests/tests/migrations
    
    the code of the file until where you have to start completion: use prisma_value::PrismaValue;
use sql_migration_tests::test_api::*;
use sql_schema_desc
    
fn json_fields_can_be_created(api: TestApi) {
    let dm = r#"
            model Test {
                id String @id @default(cuid())
                javaScriptObjectNotation Json
            }
        "#;

    api.schema_push_w_datasource(dm).send().assert_green();

    api.assert_schema().assert_table("Test", |table| {
        table.assert_column("javaScriptObjectNotation", |c| {
            if api.is_mariadb() {
                // JSON is an alias for LONGTEXT on MariaDB - https://mariadb.com/kb/en/json-data-type/
                c.assert_is_required().assert_type_family(ColumnTypeFamily::String)
            } else {
                c.assert_is_required().assert_type_family(ColumnTypeFamily::Json)
            }
        })
    });

    api.schema_push_w_datasource(dm).send().assert_green().assert_no_steps();
