How do you test code that uses PSGI/Plack?

Testing code that uses PSGI/Plack involves writing tests that can simulate HTTP requests and validate responses. You can use testing frameworks like Test::More along with the Plack::Test module to facilitate this process. Below is an example illustrating how to set up and run tests for a simple PSGI application.

This example demonstrates how to test a PSGI application using Perl's testing frameworks, ensuring the application behaves correctly under various scenarios.

#!/usr/bin/env perl use strict; use warnings; use Test::More; use Plack::Test; # A simple PSGI application my $app = sub { my $env = shift; return [200, ['Content-Type' => 'text/plain'], ['Hello World']]; }; # Create a Plack::Test object my $test = Plack::Test->create($app); # Test the application response my $response = $test->get('/'); is($response->code, 200, 'HTTP status is 200'); is($response->content, 'Hello World', 'Response content is correct'); done_testing();
