txn_test.go - Overview​

This file contains unit tests for the transaction functionality of BadgerDB, covering various scenarios such as simple transactions, read-after-write consistency, asynchronous commits, versioning, write skew detection, and interactions with iterators. It also includes tests for managed transactions.
