Moving From AUnit V1 to V2

Moving From AUnit V1 to V2

[Michael Rohan]

Hi folks,

I have some AUnit tests using AUnit v1 which compiles OK with GCC;

gcc version 4.1.2 20070925 (Red Hat 4.1.2-27)

(Fedora Core 7).  It doesn't compile with GNAT

gcc version 4.1.3 20070403 for GNAT GPL 2007 (20070402)

so I figured I'd just move to AUnit v2 (which was available with GPL
2007).  This update from V1 to V2 changed AUnit to a generic framework
which needs to be instantiated.  Does anyone have recommendations on
the updates needed?  The docs that came with V2 probably need some
updates.

Any input would be appreciated.

Take care,
Michael.

I moved from AUnit v1 to AUnit v2 in one of my projects but it was a 
while ago and I've forgotten exactly what was involved. I agree that the 
AUnit documentation is a bit lacking. I do remember that I ended up 
reading the AUnit source and looking at the examples to figure out what 
needed to be done.

Sorry I'm not more helpful.

I believe aunit.html under "doc" describes the conversion process in  
detail.  At least I know I spent a lot of time writing it.  If you've read  
that document and it's still "short", let me know.

Well there is no such file 'aunit.html' in the AUnit distribution that 
is part of GNAT GPL 2007. I do see doc/aunit/aunit.texi, but I don't 
find that file especially readable. I'm on a Windows system, but I do 
have Cygwin installed. When I execute Cygwin's make I get the following 
error:

sed: can't read ../version_information: No such file or directory
make: *** [version] Error 2

I also tried using the make that is part of GNAT GPL 2007 (together with 
whatever other Unix-like tools that are part of that package). In that 
case I get this error:

The system cannot find the path specified.
The system cannot find the path specified.

Peter,

You're both an AdaCore regular customer and a GAP member, so should use  
AdaCore's support services.  I'll send you a private email.  For everyone  
else, if we find a packaging problem, we will correct it on the Libre site.

- Ed

Hi,

I received a lot of pointers from this thread and should be able to
move ahead now.  Thank you all.

My confusion was started by the example that was installed with aunit:

/usr/gnat/share/examples/aunit

Using a copy of this as a base, I ran into compilation errors which
made me feel if this is not consistent with the distribution, I might
need additional help.  After copying /usr/gnat/share/examples/aunit/*
and /usr/gnat/lib/gnat/aunit.gpr, updating sample.gpr  and aunit.gpr
to use paths based on /usr/gnat, I got

$ gnatmake -Psample.gpr
gcc -c -g -gnatQ -gnatf -g -I- -gnatA /home/mrohan/aunit/harness.adb

Take care,
Michael.

I downloaded 2007 on 5 Jan, the aunit archive in it is

-r--r--r--   1 simon  simon  246411 Oct 17 11:03 aunit-gpl-2.01-1-src.tgz

and that does contain the html file.

I didn't have any GNAT-GPL-2007 problems with AUnit 1.05 (which came
with 2006).

I hadn't (therefore) checked out AUnit 2 - but I see that AUnit 2.01
includes notes on migrating from 1 to 2, and even a script to automate
some of the changes. Are these notes wrong?

Yes, AUnit 1.05 is fine for use within AUnit's original design  
parameters.  AUnit 2.xx was intended to address usage under constrained  
run-time environments, for example no exception propagation or dynamic  
allocation.  This change required a certain amount of interface change,  
though we tried to limit it insofar as possible.
