Testing Stores and Reactivity

Test Svelte stores in isolation and verify that derived values update correctly.

Stores in Isolation

Test Svelte stores by importing them and asserting on their values after updates.

import { count } from "$lib/stores";
import { get } from "svelte/store";
count.set(5);
expect(get(count)).toBe(5);

get(store) reads the current value synchronously, useful in tests.
