DbUnit is a JUnit extension (also usable with Ant) targeted
for database-driven projects that, among other things, puts
your database into a known state between test runs. This is
an excellent way to avoid the myriad of problems that can
occur when one test case corrupts the database and causes
subsequent tests to fail or exacerbate the damage.
DbUnit has the ability to export and import your database
data to and from XML datasets. Since version 2.0, DbUnit can
works with very large dataset when use in streaming mode.
DbUnit can also helps you to verify that your database data
match expected set of values.
