benerator is a framework for creating realistic and valid high-volume test data, used for
testing (unit/integration/load) and showcase setup.
Metadata constraints are imported from systems and/or configuration files. Data can imported from
and exported to files and systems, anonymized or generated from scratch. Domain packages provide
reusable generators for creating domain-specific data as names and addresses internationalizable
in language and region. It is strongly customizable with plugins and configuration options.
The newest version!
