perl-testing

Comprehensive testing strategies for Perl applications using Test2::V0, Test::More, prove, and TDD methodology. Always follow the RED-GREEN-REFACTOR cycle. The standard Perl testing module — widely used, ships with core. Test2::V0 is the modern replacement for Test::More — richer assertions, better diagnostics, and extensible. Place reusable helpers in t/lib/TestHelper.pm and load with use lib 't/lib' . Export factory functions like create_test_db() , create_temp_dir() , and fixture_path() via Exporter . For lightweight mock objects, use Test::MockObject to create injectable test doubles with ->mock() and verify calls with ->called_ok() . Use in-memory SQLite for database tests, mock HTTP::Tiny for API tests.
