/**
 * Helper method to test Views in the presence of concurrent compaction.

 * @param expTotalFileSlices Total number of file-slices across file-groups in the partition path
 * @param expTotalDataFiles Total number of data-files across file-groups in the partition path
 * @param includeInvalidAndInflight Whether view includes inflight and invalid file-groups.
