Plack::Middleware::TesUsertContributePlack::Middleware::Test::StashWarnings(3)NAMEPlack::Middleware::Test::StashWarnings - Test your application's
warnings
SYNOPSIS
# for your PSGI application:
enable "Test::StashWarnings";
# for your Test::WWW::Mechanize subclass:
use Storable 'thaw';
sub get_warnings {
local $Test::Builder::Level = $Test::Builder::Level + 1;
my $self = shift;
my $clone = $self->clone;
return unless $clone->get_ok('/__test_warnings');
my @warnings = @{ thaw $clone->content };
return @warnings;
}
DESCRIPTIONPlack::Middleware::Test::StashWarnings is a Plack middleware component
to record warnings generated by your application so that you can test
them to make sure your application complains about the right things.
The warnings generated by your application are available at a special
URL ("/__test_warnings"), encoded with "nfreeze" in Storable. So using
Test::WWW::Mechanize you can just "get" that URL and "thaw" in Storable
its content.
RATIONALE
Warnings are an important part of any application. Your web application
should warn its operators when something is amiss.
Almost as importantly, your web application should gracefully cope 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 correctly denies that action and
logs the failure? Are you sure it will tomorrow?
This module lets you retrieve the warnings that your forked server
issues. That way you can test that your application continues to issue
warnings when it makes sense. Catching the warnings also keeps your
test output tidy. Finally, you'll be able to see (and be notified via
failing tests) when your application issues new, unexpected warnings so
you can fix them immediately.
