Benerator is a performance test data generation tool. It can be used to completely synthesize test data or import and anonymize production data. Its emphasis is on generating valid data even for complex constraints and on being platform-independent. You can define generators for your business domain, exchange them freely (under GPL) with colleagues, and reuse them for creating data for different target platforms. It is highly extendable, supporting a wide range of service provider interfaces, and can execute scripts in JavaScript, Ruby, Python, Groovy, and other script languages.


This release brings a new hierarchical data generation and retrieval mechanism to support mongoDB and supports a scope mechanism for more sophisticated generator life cycle control. Libraries can now be distributed with generation projects. Several database-related bugs and performance issues were fixed.
