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.
