Feed your test with data
ecFeed has been created to facilitate test design and test data generation. It has a simple user interface, yet offers advanced modeling capabilities and features powerful combinatorial and random data generation algorithms. As an Eclipse plugin, EcFeed integrates with Java (also Android) test code and can directly execute generated tests. It can also be run as a standalone application. In many aspects it beats functionality of commercially available tools, but still is free and open source.
