Implements robust testing strategies for XState v5 state machines using Vitest and Jest.
This skill provides a comprehensive set of patterns and best practices for testing XState v5 state machines. It emphasizes behavioral testing over configuration checking, offering guidance on actor testing, pure transition testing for faster execution, and sophisticated mocking techniques using .provide(). Whether you are handling complex async operations with waitFor or verifying guarded transitions, this skill ensures your state logic is reliable, maintainable, and well-documented within your development workflow.
