Can you provide an example of using Zustand with Mocha

1. Create a Zustand Store

First, create a Zustand store using the `create` function from `zustand`. This store will be used to manage the state of your application.

javascript
import { create } from 'zustand';

const useCountStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 })),
}));

export default useCountStore;

2. Write Tests

Next, write tests for your Zustand store using Mocha. You can use the `beforeEach` hook to reset the state before each test and the `afterEach` hook to reset the state after each test.

javascript
import { expect } from 'chai';
import { useCountStore } from './useCountStore';

describe('Count Store', () => {
  let store;

  beforeEach(() => {
    store = useCountStore.getState();
  });

  afterEach(() => {
    store = useCountStore.getState();
  });

  it('should initialize with count 0', () => {
    expect(store.count).to.equal(0);
  });

  it('should increment the count', () => {
    store.increment();
    expect(store.count).to.equal(1);
  });
});

3. Use Mocks

To test the actions of your Zustand store, you can use mocks. For example, you can mock the `increment` action to test that it updates the state correctly.

javascript
import { expect } from 'chai';
import { useCountStore } from './useCountStore';

describe('Count Store', () => {
  let store;

  beforeEach(() => {
    store = useCountStore.getState();
  });

  afterEach(() => {
    store = useCountStore.getState();
  });

  it('should initialize with count 0', () => {
    expect(store.count).to.equal(0);
  });

  it('should increment the count', () => {
    const incrementSpy = sinon.spy(store, 'increment');
    store.increment();
    expect(incrementSpy.calledOnce).to.be.true;
    expect(store.count).to.equal(1);
  });
});

4. Use Jest

If you are using Jest, you can use the `jest.requireActual` function to mock the `zustand` module.

javascript
import { expect } from 'chai';
import { useCountStore } from './useCountStore';
import * as zustand from 'zustand';
import { jest } from '@jest/globals';

jest.mock('zustand', () => ({
  create: jest.fn(() => ({
    increment: jest.fn(),
  })),
}));

describe('Count Store', () => {
  let store;

  beforeEach(() => {
    store = useCountStore.getState();
  });

  afterEach(() => {
    store = useCountStore.getState();
  });

  it('should initialize with count 0', () => {
    expect(store.count).to.equal(0);
  });

  it('should increment the count', () => {
    store.increment();
    expect(store.count).to.equal(1);
  });
});

5. Use Vitest

If you are using Vitest, you can use the `vitest.mock` function to mock the `zustand` module.

javascript
import { expect } from 'chai';
import { useCountStore } from './useCountStore';
import * as zustand from 'zustand';
import { vitest } from 'vitest';

vitest.mock('zustand', () => ({
  create: vitest.fn(() => ({
    increment: vitest.fn(),
  })),
}));

describe('Count Store', () => {
  let store;

  beforeEach(() => {
    store = useCountStore.getState();
  });

  afterEach(() => {
    store = useCountStore.getState();
  });

  it('should initialize with count 0', () => {
    expect(store.count).to.equal(0);
  });

  it('should increment the count', () => {
    store.increment();
    expect(store.count).to.equal(1);
  });
});

By following these steps, you can effectively test your Zustand store using Mocha.
