Here are some tips to test this module without building debian package:

* test all:

  prove -l t/
  perl -Ilib t/*.t

* single test

  prove -l t/debian-dpkg.t
  perl -Ilib t/debian-dpkg.t

* pick test case for t/model_test.t

model_test can be quite long to execute as it runs several test cases
(in fact one for every example file located in t/model_test.d/*-examples)

Syntax is:

  perl -Ilib t/model_test.t <flag> <group> <example>

flag can be:
- t: add more verbose trace on STDOUT
- l: print logs configured in ~/.log4config-model
- e: print stack trace when exceptions are thrown

To find group and example, run 
  perl -Ilib t/model_tests.t |grep 'Beginning subtest'

Each subtest name can be used as group and example (example can be a pattern).

For instance:

$ perl -Ilib t/model_tests.t x dpkg-copyright oar   
ok 1 - compiled
# Beginning dpkg-copyright test (t/model_tests.d/dpkg-copyright-test-conf.pl)
# dpkg-copyright uses Dpkg::Copyright model on file copyright
# Beginning subtest dpkg-copyright oar
ok 2 - Copied dpkg-copyright example oar
not ok 3 - Read configuration and created instance with init() method with warning check 
#   Failed test 'Read configuration and created instance with init() method with warning check '
#   at /usr/share/perl5/Config/Model/Tester.pm line 156.

# End of subtest dpkg-copyright moarvm-from-scratch
# End of dpkg-copyright test
ok 28 - test memory cycle

# Looks like you failed 1 test of 28.

The 'x' flag is ignored. The above command runs 2 subtests that match
'oar': 'oar' and 'moarvm'.

A pattern must be used to run only 'oar' subtest':

$ perl -Ilib t/model_tests.t x dpkg-copyright '\boar\b'
ok 1 - compiled
# Beginning dpkg-copyright test (t/model_tests.d/dpkg-copyright-test-conf.pl)
# dpkg-copyright uses Dpkg::Copyright model on file copyright
# Beginning subtest dpkg-copyright oar
ok 2 - Copied dpkg-copyright example oar
not ok 3 - Read configuration and created instance with init() method with warning check 
#   Failed test 'Read configuration and created instance with init() method with warning check '

ok 4 - Ran dump_tree (no warning check)

ok 6 - Dumped dpkg-copyright config tree in custom mode
ok 7 - first check 'Files:"sources/extra/orpheus/modules/lua-signal/lsignal.c" License short_name' value
ok 8 - dpkg-copyright write back done

# End of dpkg-copyright test
ok 13 - test memory cycle

You can run a whole group by omitting the subtest name:

 $ perl -Ilib t/model_tests.t x dpkg-control
