/**
 * This helper class is designed to facilitate integration testing of Firestore queries that
 * require composite indexes within a controlled testing environment.
 *
 * <p>Key Features:
 *
 * <ul>
 *   <li>Runs tests against the dedicated test collection with predefined composite indexes.
 *   <li>Automatically associates a test ID with documents for data isolation.
 *   <li>Utilizes TTL policy for automatic test data cleanup.
 *   <li>Constructs Firestore queries with test ID filters.
 * </ul>
