+## What is dbUnit?
+DbUnit is a JUnit extension for testing with databases.
+It puts your database into a known state before each test runs
+(preventing cascading failures from shared database corruption),
+verifies table correctness after a test runs,
+and restores the database tables in prep for the next test.
+
+Founded in 2002 on SourceForge, in May of 2026, dbUnit completed moving to GitHub.com.
+While dbUnit's first home for 24 years was SourceForge, dbUnit moved through multiple external CI systems for the pipeline build verification.
+With the success at GitHub for over a year due to its well-done CI system, the entire project moved to GitHub, including the issues.
