=head1 NAME
|
|
|
|
Test - provides a simple framework for writing test scripts
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use strict;
|
|
use Test;
|
|
|
|
# use a BEGIN block so we print our plan before MyModule is loaded
|
|
BEGIN { plan tests => 14, todo => [3,4] }
|
|
|
|
# load your module...
|
|
use MyModule;
|
|
|
|
ok(0); # failure
|
|
ok(1); # success
|
|
|
|
ok(0); # ok, expected failure (see todo list, above)
|
|
ok(1); # surprise success!
|
|
|
|
ok(0,1); # failure: '0' ne '1'
|
|
ok('broke','fixed'); # failure: 'broke' ne 'fixed'
|
|
ok('fixed','fixed'); # success: 'fixed' eq 'fixed'
|
|
ok('fixed',qr/x/); # success: 'fixed' =~ qr/x/
|
|
|
|
ok(sub { 1+1 }, 2); # success: '2' eq '2'
|
|
ok(sub { 1+1 }, 3); # failure: '2' ne '3'
|
|
ok(0, int(rand(2)); # (just kidding :-)
|
|
|
|
my @list = (0,0);
|
|
ok @list, 3, "\@list=".join(',',@list); #extra diagnostics
|
|
ok 'segmentation fault', '/(?i)success/'; #regex match
|
|
|
|
skip($feature_is_missing, ...); #do platform specific test
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
L<Test::Harness> expects to see particular output when it executes
|
|
tests. This module aims to make writing proper test scripts just a
|
|
little bit easier (and less error prone :-).
|
|
|
|
=head1 TEST TYPES
|
|
|
|
=over 4
|
|
|
|
=item * NORMAL TESTS
|
|
|
|
These tests are expected to succeed. If they don't something's
|
|
screwed up!
|
|
|
|
=item * SKIPPED TESTS
|
|
|
|
Skip is for tests that might or might not be possible to run depending
|
|
on the availability of platform specific features. The first argument
|
|
should evaluate to true (think "yes, please skip") if the required
|
|
feature is not available. After the first argument, skip works
|
|
exactly the same way as do normal tests.
|
|
|
|
=item * TODO TESTS
|
|
|
|
TODO tests are designed for maintaining an B<executable TODO list>.
|
|
These tests are expected NOT to succeed. If a TODO test does succeed,
|
|
the feature in question should not be on the TODO list, now should it?
|
|
|
|
Packages should NOT be released with succeeding TODO tests. As soon
|
|
as a TODO test starts working, it should be promoted to a normal test
|
|
and the newly working feature should be documented in the release
|
|
notes or change log.
|
|
|
|
=back
|
|
|
|
=head1 RETURN VALUE
|
|
|
|
Both C<ok> and C<skip> return true if their test succeeds and false
|
|
otherwise in a scalar context.
|
|
|
|
=head1 ONFAIL
|
|
|
|
BEGIN { plan test => 4, onfail => sub { warn "CALL 911!" } }
|
|
|
|
While test failures should be enough, extra diagnostics can be
|
|
triggered at the end of a test run. C<onfail> is passed an array ref
|
|
of hash refs that describe each test failure. Each hash will contain
|
|
at least the following fields: C<package>, C<repetition>, and
|
|
C<result>. (The file, line, and test number are not included because
|
|
their correspondance to a particular test is tenuous.) If the test
|
|
had an expected value or a diagnostic string, these will also be
|
|
included.
|
|
|
|
The B<optional> C<onfail> hook might be used simply to print out the
|
|
version of your package and/or how to report problems. It might also
|
|
be used to generate extremely sophisticated diagnostics for a
|
|
particularly bizarre test failure. However it's not a panacea. Core
|
|
dumps or other unrecoverable errors prevent the C<onfail> hook from
|
|
running. (It is run inside an C<END> block.) Besides, C<onfail> is
|
|
probably over-kill in most cases. (Your test code should be simpler
|
|
than the code it is testing, yes?)
|
|
|
|

|
