Pull Request Overview

This PR refactors test topic names to use dynamically generated UUIDs instead of hardcoded strings. The goal is to normalize topic names across the test suite to avoid conflicts and ensure test isolation.

Key changes:

• Introduces a TestTopics module that generates unique topic names with UUID suffixes
• Replaces all hardcoded topic name strings throughout the test suite with calls to the new module
• Updates topic creation logic in the test setup to use the new dynamic topic names

The consumer variable is not defined in this context. This line appears to be within the notify_listener function but no consumer is being passed to the function or created locally.

Suggested change

	def notify_listener(listener, &block)
	def notify_listener(consumer, &block)

[nitpick] Removing the .to_s call may cause issues if the TestTopics methods ever return non-string values. Consider adding explicit string conversion for safety.

Suggested change

	create_topic_handle = admin.create_topic(topic, partitions, 1)
	create_topic_handle = admin.create_topic(topic.to_s, partitions, 1)
