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.
