Comprehensive testing strategies for Perl applications using Test2::V0, Test::More, prove, and TDD methodology. Writing new Perl code (follow TDD: red, green, refactor) Designing test suites for Perl modules or applications Reviewing Perl test coverage Setting up Perl testing infrastructure Migrating tests from Test::More to Test2::V0 Debugging failing Perl tests 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. Superior deep comparison with hash/array builders Better diagnostic output on failures Subtests with cleaner scoping Extensible via Test2::Tools:: plugins Backward-compatible with Test::More tests Place reusable helpers in t/lib/TestHelper.pm and load with use lib 't/lib'. Export factory functions like createtestdb(), createtempdir(), and fixturepath() via Exporter. For lightweight mock objects, use Test::MockObject to create injectable test doubles with ->mock() and verify calls with ->calledok(). Use in-memory SQLite for database tests, mock HTTP::Tiny for API tests. Follow TDD: Write tests before implementa
