NAME

Test::DiagINC - List modules and versions loaded if tests fail

VERSION

version 0.002

SYNOPSIS

# Load *BEFORE* Test::More
use if $ENV{AUTOMATED_TESTING}, 'Test::DiagINC';
use Test::More;

DESCRIPTION

Assuming you shipped your module to CPAN with working tests, test failures from CPAN Testers might be due to platform issues, Perl version issues or problems with dependencies. This module helps you diagnose deep dependency problems by showing you exactly what modules and versions were loaded during a test run.

When this module is loaded, it sets up an END block that will take action if a program exits with a non-zero exit code. If that happens, this module prints out the names and version numbers of non-local modules appearing in %INC at the end of the test.

For example:

$ perl -MTest::DiagINC -MTest::More -e 'fail("meh"); done_testing'
not ok 1 - meh
#   Failed test 'meh'
#   at -e line 1.
1..1
# Looks like you failed 1 test of 1.
# Listing modules and versions from %INC
#   5.018002 Config
#       5.68 Exporter
#       5.68 Exporter::Heavy
#       1.07 PerlIO
#   1.001002 Test::Builder
#   1.001002 Test::Builder::Module
#      0.001 Test::DiagINC
#   1.001002 Test::More
#       1.22 overload
#       0.02 overloading
#       1.07 strict
#       1.03 vars
#       1.18 warnings
#       1.02 warnings::register

NOTE: Because this module uses an END block, it must be loaded before Test::More so that the Test::More's END block has a chance to set the exit code first. If you're not using Test::More, then it's up to you to ensure your code generates the non-zero exit code (e.g. die() or exit(1)).

Modules that appear to be sourced from below the current directory when Test::DiagINC was loaded will be excluded from the report (e.g. excludes local modules from lib/, t/lib, and so on).

The heuristic of searching %INC for loaded modules may fail if the module path loaded does not map to a package within the module file or if that package does not define a $VERSION.

If Test::More is loaded, the output will go via the diag function. Otherwise, it will just be sent to STDERR.
