Subject: How to implement this in unit testing

Hi, 
If I want to implement something like this in Ruby Unit Testing: 
test_z_lessthan_20 
    x = choose(1..5) 
    y = choose(0..3) 
    z = x * y 
    assert(z < 20) 
    end_choice 
    end_choice 
end 
 
The idea here is to run the previous test for all x and y values. My
initial idea is to parse previous code and generate something like
this: 
test_z_lessthan_20 
    [1..5].each do |x| 
        [0..3].each do |y| 
             z = x * y 
             assert(z < 20) 
        end 
     end 
end 
My question is what is the best way to parse previous code i.e. is
there a parser where I will just change small parts of it to pasre the
choose part. 
Also is there a way to implement the previous code dynamically during
runtime or at least do the parsing and change on the fly instead of
creating some code statically. 
 
Thanks
