NDbUnit is a .NET library for managing database state during unit testing.

NDbUnit may be used to increase repeatability in unit tests that interact with a database by ensuring that the database's state is consistent across execution of tests. NDbUnit does this by allowing the unit test to perform an operation on a dataset before or after the execution of a test, thus ensuring a consistent state.

NDbUnit:

• is an open-source LGPL-licensed project
• is written in C#
• compiled against the .NET 2.0 CLR and runs with the 2.0, 3.0, and 3.5 fx releases
• borrows many ideas from DbUnit, and makes them available for the .NET platform

NDbUnit supports the following Database Server Targets:

• Microsoft SQL Server 2005 and 2008
• Microsoft SQL Server CE 2005 and 2008
• Microsoft OleDB-supported databases
• SQLLite
• MySQL
• Oracle (not yet available, coming mid-2009)
