//! DDL Index Basic Tests
//!
//! Test coverage:
//! - CREATE TAG INDEX - Create tag index
//! - CREATE EDGE INDEX - Create edge index
//! - DROP TAG INDEX - Delete tag index, with IF EXISTS
//! - DROP EDGE INDEX - Delete edge index, with IF EXISTS
//! - DROP INDEX - Bare index drop (defaults to tag index), with IF EXISTS
