[techniq]

Some tests have been setup when ran under React/jest, but need reintegrated, like with vitest or uvu

• vitest
• uvu
  • SvelteKit uses uvu and appears to setup it's own orchestration.
    • Switched to vitest
  • snapshot testing
  • Rich Harris's describe
  • asserts
    • uvu/assert
    • chai
• mocks / stubs / spies
  • https://sinonjs.org/
  • https://github.com/therealparmesh/snoop
  • Add uvu/spy package lukeed/uvu#10
  • Mock Service Worker (msw)
    • Using Mock Service Worker with Vitest and fetch
