… await and Promise objects to make test logic comprehension easier. Remove the incorrect assertion that on the first and subsequent call to onBatchSuccess that the number of transformed documents is always greater than or equal to the batch size. This is not always the case. Sometimes on the first callback the number of transformed docs in the summary is less than the batch size.

Pull Request Overview

This PR modernizes Node.js test files by replacing callback-based patterns with modern async/await syntax and Promises, specifically targeting intermittent test errors. The changes aim to improve test reliability and code comprehension by eliminating complex nested callback structures.

Key changes:

• Convert all test functions from callback-based (done()) to async/await pattern
• Replace nested .then()/.catch() chains with Promise-based patterns
• Remove incorrect assertions about batch completion document counts
