Hi Steve,

There are tools that will do this for you on java projects and in
nearly every case that I've seen them used, the result has been 100
line test methods, one per object method, that take the object through
multiple states, become impossible to understand, and often just get
commented out.

Worse, even though you sell it as a tool for dealing with legacy code
(code without tests), it will end up becoming the tool people use and,
even worse than that, they'll think it's BDD because it creates specs
and not tests.

I beg you (I'm on my knees as I'm writing this) to throw this
manuscript in the fire now!
