persistence4j is a small and lightweight Java object persister that uses JDBC to persist data into a relational database. The library frees you from writing the Data transfer objects - just create a POJO and simply save it. Transactional and non-transactional connections are supported and can be configured from the simple properties file.
Dummy Data Generator is a tool that generates dummy data for populating systems for testing. The data includes names, addresses, email addresses, phone numbers, and social "connections". Names are generated by using US Census data on the most common names. Email addresses are just a random string for the user portion and always use "example.com" for the domain. Currently the only output format is CSV.
MASH is a modular, automated script harness. It allows users to implement simple harnesses that perform work external to a system. The framework will invoke that harness as outlined by an XML script. For example, when using the framework to test a system you could create a script that cleans and loads a database, FTPs some data, submits a login form, and verifies HTTP information. Harnesses can easily be built to do almost anything (many harnesses are provided), not just Web page verification. While harnesses are written in Java, the scripts may be run against any type of system as harnesses are intended to act as clients.
