SKILL.md

Test composables based on their dependency type: Independent (direct testing) or Dependent (requires component context).

| Independent | Uses only reactivity APIs (ref, computed, watch) | Test directly like functions | | Dependent | Uses lifecycle hooks (onMounted) or inject | Use withSetup or useInjectedSetup helpers |

Independent composables use only Vue's reactivity system without lifecycle hooks or dependency injection.

Test Vue 3 composables with Vitest following best practices. Use when writing tests for composables, creating test helpers for Vue reactivity, or when asked to "test a composable", "write tests for use*", or "help test Vue composition functions". Covers independent composables (direct testing) and dependent composables (lifecycle/inject testing with helpers). Source: alexanderop/workouttracker.
