  ADD_TEST(testname Exename arg1 arg2 ...)
[..]
by executing Exename with the specified arguments.  Exename can be
either an executable built by this project or an arbitrary executable
on the system (like tclsh).

So you can specify any command there (such as a shell script that generates
results, compares them with ref.text, and which exits with non-zero error
code if the comparison is not exact).
