How can I generate strings that satisfy some restrictions?

Question

Can anyone give me a hand with techniques to generate strings that satisfy certain restrictions.

For example, say I need to generate strings s and t such that

      length(s) < length(t)
      length(t) > 12
      t contains at least 3 capital letters
and   s contains a 2

And I don't mean this particular example but some generic techniques to generate strings that satisfy certain conditions.

Not homework. I just need to generate strings and integers satisfying some conditions and haven't found any better techniques than Boundary value analysis and equivalence partitioning. Those don't seem enough, so I'm asking to know if someone with more experience in this matters can guide my research. Thanks! — Manuel Araoz, Jan 20 '10 at 11:13
