Mocking layers when testing Effect Atom

import { Atom } from "@effect-atom/atom-react"
import { Effect } from "effect"

class Users extends Effect.Service<Users>()("app/Users", {
  effect: Effect.gen(function* () {
    const getAll = Effect.succeed([
      { id: "1", name: "Alice" },
      { id: "2", name: "Bob" },
      { id: "3", name: "Charlie" },
    ])
    return { getAll } as const
  }),
}) {}

// Create a `AtomRuntime` from a `Layer`.
//
//         ┌─── Atom.AtomRuntime<Users>
//         ▼
const runtimeAtom = Atom.runtime(Users.Default)

// You can then use the `AtomRuntime` to make Atoms that use the services from the `Layer`.
const usersAtom = runtimeAtom.atom(
  Effect.gen(function* () {
    const users = yield* Users
    return yield* users.getAll
  }),
)
