Vitest-based unit tests follow the AAA (Arrange-Act-Assert) pattern: set up your test data, execute the function, then verify the output. This Skill provides templates and conventions for writing comprehensive tests for lib/ functions, schema validation, canvas utilities, and business logic with high coverage and meaningful assertions.

The AAA pattern structures tests into three phases: Arrange (set up data), Act (call the function), and Assert (check results). This makes tests readable, maintainable, and easier to debug. It's the standard convention for this project's test suite, ensuring consistency across all unit tests.

Create Vitest test files that validate schema behavior and canvas utility functions by following project naming conventions and file structure. The Skill provides test templates for schema validation logic and canvas behavior, helping you achieve high coverage and catch regressions early.

Yes. Vitest supports writing regression tests that verify a bug fix works and prevent the issue from recurring. This Skill covers creating regression tests within the project's testing framework, following AAA patterns and existing test conventions to maintain quality standards.

This Skill enforces the project's specified file structure and naming conventions for test files, ensuring consistency across the codebase. Following these conventions makes tests discoverable, maintainable, and aligned with team standards.

Performance tests verify that functions meet speed and efficiency requirements. This Skill includes guidance on creating performance tests for lib/ functions using Vitest, following project conventions and the AAA pattern to measure and validate behavior under load.
