Any open source tool for test data generation

[nivetha]

Hi All,

I'm looking for some open source test data generation tool, where i can define some rules for test data generation. For ex, rule for 'username' field is it should have atleast 1 number. So, if i pass

fieldname, datatype, length, valid value, rule
username, alphanumeric, 20, mike0, min. 1 number

then, i expect it to generate

username, mike0, pass
username, mike123, pass
username, mike@#, fail
username, mike, fail
username, , fail
username, mike123456mike1234567, fail
etc

Any idea?
