How to write your own DbUnit
summary
Shows how to build a small JUnit extension that reads YAML/CSV/XML data files, instantiates an etcd Java client, etcd dataset seeds keys before a test and compares persisted state after, throwing an exception on mismatches; the demo test runs green. Uses DBUnit concepts wrapped as DBWriter features (comparison strategies, expected datasets, cleanup) and notes integration with Flyway/Liquibase and testcontainers, plus pitfalls: multi-DB support, diff output detail, dataset merging and scripting for dynamic values.
