What problem does it solve?

This Skill helps R developers adopt robust, maintainable testing practices for R packages by using testthat 3. It provides a clear blueprint for structuring tests, leveraging fixtures, snapshots, and mocking, while promoting consistent expectations and reliable results.

Core Features & Use Cases

  • Test organization and patterns for testthat 3 (describe/it and test_that) to create readable, navigable suites.
  • Fixtures, snapshot testing, and mocking strategies, with guidance on cleanup using withr for deterministic tests.
  • Guidance on building CI-ready tests and scalable test suites that cover typical edge cases in package development.

Quick Start

Create a basic testthat 3 suite in your package and start writing describe/it or test_that blocks to cover core functions.
