Plack::Test::Suite(3)

💖 Plack::Test::Suite 💖

okay bestie, this is Plack::Test::Suite from the User Contributed Perl Documentation, and it's literally the glow-up test suite for your shiny new PSGI server handler. she's giving quality control, she's giving "does your handler actually work", and she's fr fr not here to play. 🎀

✨ NAME ✨

Plack::Test::Suite — the test suite that tests your Plack handlers. no cap, that's the whole job. 💅

---

🌸 SYNOPSIS 🌸

okay so here's the vibe, copy this energy:

use Test::More;
use Plack::Test::Suite;
Plack::Test::Suite->run_server_tests('Your::Handler');
done_testing;

that's it. that's the whole ritual. 🦋

👑 DESCRIPTION 👑

so Plack::Test::Suite is a test suite that exists to test a brand new PSGI server implementation. iconic behavior honestly.

what it does: it automatically loads a new handler environment, and then it uses LWP to send HTTP requests to the local server. why? to make sure your handler implements the PSGI specification correctly. it's giving vibe check but for compliance. ✨

🚨 now listen close because this part is important: the handler name does not include the "Plack::Handler::" prefix. so if you have a new Plack handler called Plack::Handler::Foo, your test script would look like:

Plack::Test::Suite->run_server_tests('Foo');

see how it's just 'Foo'? the Plack::Handler:: part is implied, she doesn't need it spelled out. 💀

and to the developers out there writing Plack applications: bestie, you should be looking at "Plack::Test" for your testing needs instead. because subclassing "Plack::Handler" is for developing server implementations, not apps. two different lanes, two different destinies, know your role. 🫶
