NAME¶
Test::HTTP::Server::Simple::StashWarnings - catch your forked server's warnings
SYNOPSIS¶
package My::Webserver::Test;
use base qw/Test::HTTP::Server::Simple::StashWarnings My::Webserver/;
sub test_warning_path { "/__test_warnings" }
package main;
use Test::More tests => 42;
my $s = My::WebServer::Test->new;
my $url_root = $s->started_ok("start up my web server");
my $mech = WWW::Mechanize->new;
$mech->get("$url_root/some_action");
$mech->get("/__test_warnings");
my @warnings = My::WebServer::Test->decode_warnings($mech->content);
is(@warnings, 0, "some_action gave no warnings");
DESCRIPTION¶
Warnings are an important part of any application. Your web application should
warn the user when something is amiss.
Almost as importantly, we want to be able to test that the web application
gracefully copes with bad input, the back button, and all other aspects of the
user experience.
Unfortunately, tests seldom cover what happens when things go poorly. Are you
"sure" that your application checks authorization for that action?
Are you "sure" it will tomorrow?
This module lets you retrieve the warnings that your forked server throws. That
way you can test that your application continues to throw warnings when it
makes sense. Catching the warnings also keeps your test output tidy. Finally,
you'll be able to see when your application throws new, unexpected warnings.
SETUP¶
The way this module works is it catches warnings and makes them available on a
special URL (which must be defined by you in the "test_warning_path"
method). You can use "WWW::Mechanize" (or whichever HTTP agent you
prefer) to download the warnings. The warnings will be serialized. Use
decode_warnings to get the list of warnings seen so far (since last request
anyway).
Warnings are encoded using Storable by default, but your subclass may override
the "encode_warnings" and "decode_warnings" methods.
TIPS¶
Setting the "TEST_VERBOSE" environment variable to a true value will
cause warnings to be displayed immediately, even if they would be captured and
tested later.
