End-to-end DSL unit testing? [message #1095827]

I'm looking for thoughts on unit tests which, given some input text in my DSL and some runtime inputs, will determine whether the correct output is emitted.

Example: Quote:

When the code generated from
x should not be null
(in some constraint/validation DSL) is executed with a null input, it should emit
x is null but shouldn't be

Is this a good testing practice? If not, why?

Has anyone done this kind of testing, and/or have any advice on how to implement it? A unit test which generates,compiles, and then executes the compiled code is new to me.

I'm generating Xtend code, if it matters.
