[mxsm]

Prerequisites

• I have searched existing test issues

Test Scope

Module: topic queue table
File: rocketmq-namesrv/src/route/tables/topic_table.rs
Coverage: cover helper methods used by write-permission admin requests and route manager snapshots.

Test Cases

• update_queue_data_perm updates only the targeted topic and broker.
• update_queue_data_perm returns false when the topic or broker is missing.
• get_topic_queues_map returns public broker names and cloned queue data for a topic.
• iter_all_with_data reports all topics and queue entries after multiple inserts.
• Validate with cargo test -p rocketmq-namesrv topic_table.
