Dear.all,
I have a problem that I solved in a fairly acceptable way, but I would like=
 to hear from you if there are some kind of "better practices" that I could=
 use.

The problem is this: sometimes, while writing some software, I develop some=
 packages that could be used elsewhere, so I "extract" them in a library of=
 their own with their own project file that is "with-ed" inside the project=
 file of the larger software.

When I "isolate" the package into its own library,  I like also to add some=
 testing code.  The problem is that if I declare the project to be a librar=
y project (which is just natural) I cannot have an executable. =20

In the past, I solved this problem by declaring the project to be a non-lib=
rary one; nowadays I declare it to be a library project and then add a fold=
er test/ with its src/ folder with the test programs and a specific project=
 file that "with-s" the library project. =20

Let me try drawing a picture relative to a library "foo"=20

foolib/
...|
...+-- foolib.gpr
...+-- src/
...+-- obj/
...+-- test/
..........|
..........+--foolib_test.gpr
..........+--obj/
..........+--src/
................|
...............+-- foo_test_1.adb
...............+-- foo_test_2.adb
...............+-- foo_test_3.adb

I hope you got the idea.=20

Do you have any suggestion about a different organization?  Do there exist =
some kind of "best practice" for this?

Thank you in advance for your help
