SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the guesswork and inconsistency of writing Perl test suites, addresses low test coverage, and simplifies adopting test-driven development (TDD) and modern testing frameworks for Perl applications.

Core Features & Use Cases

  • TDD Workflow Support: Step-by-step guidance for the red-green-refactor cycle, with concrete examples for writing failing tests first, implementing minimal code, and refactoring safely.
  • Modern Testing Framework Coverage: Full documentation for Test2::V0 modern assertions, subtests, deep comparison builders, and exception testing, plus migration paths from legacy Test::More.
  • Test Infrastructure & Coverage Tools: Instructions for organizing test directories, running tests with the prove runner, mocking external dependencies with Test::MockModule, and generating coverage reports with Devel::Cover. For example, a Perl developer building a new user authentication module can use this Skill to set up a TDD workflow, write comprehensive unit tests, mock external API calls, and ensure 80%+ code coverage before merging.

Quick Start

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

FAQPage Schema
How do I migrate Perl tests from Test::More to Test2::V0?

Migrating Perl tests from Test::More to Test2::V0 involves adopting modern assertions, subtests, and deep comparison builders. This Skill provides specific migration paths to transition legacy test suites into the Test2::V0 framework.

What is the best way to structure a TDD workflow for Perl modules?

Structuring a TDD workflow for Perl modules follows the red-green-refactor cycle: writing failing tests first, implementing minimal code to pass, and refactoring safely. This Skill provides step-by-step guidance and concrete examples for each phase.

How do I mock external dependencies in Perl tests using Test::MockModule?

Mocking external dependencies in Perl tests uses Test::MockModule to intercept and override module behaviors. This Skill provides operational guidance for configuring mocks to isolate units and validate interactions without hitting external APIs.

Can I generate code coverage reports for Perl test suites using Devel::Cover?

Generating code coverage reports for Perl test suites uses Devel::Cover to analyze and report test execution metrics. This Skill offers instructions for running coverage analysis to ensure 80%+ coverage before merging.

Does prove work with Test2::V0 for running Perl test suites?

Yes, prove works with Test2::V0 for running Perl test suites. The prove test runner executes Test2::V0 assertions and subtests seamlessly, and this Skill provides configuration instructions for running tests with verbose output.

Why are my Perl tests brittle and how can I make them consistent?

Perl tests become brittle due to inconsistent suite design and low test coverage. This Skill eliminates guesswork by applying standardized Test2::V0 assertions, organized test directories, and TDD practices to create reliable test suites.
