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.
