Pull Request Overview

This PR refactors the ExpectMessageBatch test helper function to support processing messages across multiple batches, improving test flexibility when dealing with message data that may be split across multiple events.

• The ExpectMessageBatch function now accepts TList<TRow> instead of TBatch and loops to process multiple message batches
• A new expectNewDataArrived parameter controls whether to wait for new data arrival events
• Multiple test calls to ExpectNewDataArrived have been removed, as they are now handled within ExpectMessageBatch
