Reactivity

Subset of Solid's reactive utilities used by Circuit to load nested hierarchical data.

Test Utils

Some test-related utils are exported from the test-utils entrypoint.

import {
  waitLoadedAccessor,
  waitSignal,
  spySignal,
} from '@circuit/reactivity/test-utils'

• waitSignal(signal, condition) is a function that returns a promise that resolves when the given LoadableSignal is called and the given condition is met.

• waitLoadedAccessor(signal) is a function that returns a promise that resolves when the given LoadableAccessor is loaded. This is useful when you want to guarantee that a test is waiting for an LoadableAccessor to be loaded.

• spySignal(signal) is a function that returns a jest.Mock that is spying on the given LoadableAccessor. This is useful when you want to verify that a signal has been called after any of its dependencies were updated.
