SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Writing reliable, maintainable test suites for Perl applications is often inconsistent, with low coverage and ad-hoc workflows that fail to catch regressions early.

Core Features & Use Cases

  • TDD Workflow Guidance: Step-by-step red-green-refactor cycle for Perl development, with concrete code examples for writing failing tests first.
  • Modern & Legacy Testing Patterns: Support for both the modern Test2::V0 framework and the core Test::More module, including deep comparison, subtests, and skip/TODO logic.
  • Tooling Integration: Best practices for the prove test runner, Test::MockModule for mocking external dependencies, and Devel::Cover for tracking code coverage.
  • Use Case: For example, when developing a Perl API, use this skill to set up a test suite that mocks external database calls, validates error handling, and ensures 80%+ coverage before merging code.

Quick Start

Use the perl-testing skill to write a failing test for your new Perl module's add function, implement the minimal code to pass it, and run the test suite with prove to verify it works.

FAQPage Schema
How do I write a Perl test suite using TDD?

Perl TDD uses a red-green-refactor workflow where you write a failing Test2::V0 test first, implement the minimal code to pass it, and run the suite with prove. This ensures high coverage and early regression detection.

How do I migrate from Test::More to Test2::V0?

Migrating to Test2::V0 involves replacing legacy Test::More assertions with modern Test2::V0 equivalents. This skill provides standardized migration patterns for deep comparisons, subtests, and skip/TODO logic to modernize your Perl testing infrastructure.

How do I mock external dependencies in Perl tests?

Mocking external dependencies in Perl tests uses Test::MockModule to intercept and stub external database or API calls. This allows you to isolate unit tests, validate error handling, and ensure modules function correctly without live external connections.

What is the best way to track code coverage in Perl?

Tracking Perl code coverage uses Devel::Cover alongside the prove test runner. This combination analyzes test execution to report untested code paths, helping you enforce minimum coverage thresholds like 80% before merging code.

Can I use prove to run both legacy and modern Perl tests together?

Yes, the prove test runner executes both legacy Test::More and modern Test2::V0 test scripts. This allows you to incrementally upgrade your test suite without breaking existing tests during your migration process.

Why are my Perl test suites failing to catch regressions?

Perl test suites often miss regressions due to inconsistent ad-hoc workflows and low coverage. Implementing standardized Test2::V0 assertions and tracking coverage with Devel::Cover eliminates these gaps and catches failures early.
