Quick Start

import { createTestScope, mockSubscribable, collectValues } from '@stateloom/testing';
import { signal, computed } from '@stateloom/core';

// Isolated test scope
const scope = createTestScope();
const count = scope.run(() => signal(0));

// Collect reactive values over time
const values = collectValues(count);
count.set(1);
count.set(2);
expect(values()).toEqual([0, 1, 2]);

// Mock subscribable for unit tests
const mock = mockSubscribable(42);
expect(mock.get()).toBe(42);
mock.set(99);
