It seems there is another GNAT 2010 trick here. In project files (*.gpr =
 =

files), this may be required to turn all "-gnatwa.Xe" into "-gnatwa.X". =
 =

"-gnatwa.Xe" tells GPRBuild to treat warnings as error, and there are  =

warnings like
=E2=80=9Cmath-test.adb:13:07: warning: call to obsolescent procedure "As=
sert"  =

declared at aunit-assertions.ads:113=E2=80=9D
which occurs and would otherwise makes the compilation failed (as this e=
nd  =

up to be treated as error).

About AUnit: just seen about what it is, how it is set up and how it  =

works. Seems a question is still pending : =E2=80=9Chow to be sure the t=
est cover  =

all relevant case ?=E2=80=9D. I do not see a way to be sure testing cove=
r all  =

cases. That is the main limitation of this kind of approach. May be this=
  =

is nice for regression tests and tests cases revealed during application=
's  =

life time... however, I don't believe this can be used too much soon in =
a  =

development stage. Pretty sure this is best used just after real use or =
 =

deployment has been started.


-- =

There is even better than a pragma Assert: a SPARK --# check.
--# check C and WhoKnowWhat and YouKnowWho;
--# assert Ada;
--  i.e. forget about previous premises which leads to conclusion
--  and start with new conclusion as premise.
