pitrou opened a new issue, #45279: URL: https://github.com/apache/arrow/issues/45279
### Describe the enhancement requested Currently, many tests for the Grouper and KeySegmenter implementations are present in `acero/hash_aggregate_test.cc`. We should move them into `arrow/compute/row/grouper_test.cc` where they belong. This will also make `hash_aggregate_test.cc` slightly smaller and shorter to compile. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
