SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you prevent regressions in Perl applications by teaching practical, repeatable testing strategies for building reliable test suites and validating behavior early.

Core Features & Use Cases

  • Modern assertions with Test2::V0: Write clearer subtests and more informative deep comparisons than legacy patterns.
  • Prove-driven test execution: Organize tests in a standard structure and run them efficiently for local development and CI.
  • Mocking and coverage for accountability: Replace flaky external dependencies with mocks and measure coverage using Devel::Cover.
  • Test-Driven Development (TDD): Apply RED-GREEN-REFACTOR to go from failing tests to minimal implementation and then improve design.

Quick Start

Use the perl-testing skill to design a TDD workflow for a Perl module by writing a failing test first, then implementing the smallest change to make it pass, and finally running it with prove to confirm behavior stays correct.

FAQPage Schema
How do I structure a TDD workflow for a Perl module using prove?

Perl testing workflows use Test2::V0 for modern assertions and prove to execute test suites. Test2::V0 enables clearer subtests and informative deep comparisons than legacy patterns, helping validate behavior early and prevent application regressions.

How do I mock external dependencies in Perl tests?

Perl testing supports mocking external dependencies to isolate components and replace flaky systems during test execution. Mocks ensure consistent unit and integration behavior validation without relying on live external systems.

What is the best way to measure Perl test coverage with Devel::Cover?

Devel::Cover measures Perl test coverage to provide accountability for test suites. Integrating coverage measurement with standard prove workflows identifies untested code paths and improves overall software reliability.

Does Test2::V0 work with subtest organization and deep data structure assertions?

Test2::V0 supports subtest organization and deep data structure assertions for Perl testing. It provides clearer and more informative deep comparisons than legacy patterns, enabling precise validation of complex nested data.

How do I handle skipping tests and TODO blocks in Perl testing?

Perl testing handles skipping tests and TODO blocks for managing incomplete features and platform-specific exceptions. These isolation techniques allow test suites to continue running while deferring expected behavior assertions.
