How can I test @shopify/shopify-api with Jest?

To test @shopify/shopify-api with Jest, follow these technical steps:

1. Install Required Packages:

Ensure you have Jest and the Shopify API package installed:
bash

npm install jest @shopify/shopify-api

2. Set Up Jest Configuration:

Create a Jest configuration file if you don't have one (jest.config.js)

3. Mock Shopify API:

Create a mock for the Shopify API to isolate your tests from actual API calls. In a mocks directory, create a file for the Shopify API mock (mocks/@shopify/shopify-api.js):

const { Shopify } = jest.requireActual('@shopify/shopify-api');

const mockShopify = {
  Auth: {
    validateAuthCallback: jest.fn(),
    beginAuth: jest.fn(),
    completeAuth: jest.fn(),
  },
  Clients: {
    Rest: jest.fn().mockImplementation(() => ({
      get: jest.fn(),
      post: jest.fn(),
      put: jest.fn(),
      delete: jest.fn(),
    })),
  },
  // Add other parts of the API you need to mock
};

module.exports = { Shopify: mockShopify };```


const { Shopify } = jest.requireActual('@shopify/shopify-api');

const mockShopify = {
  Auth: {
    validateAuthCallback: jest.fn(),
    beginAuth: jest.fn(),
    completeAuth: jest.fn(),
  },
  Clients: {
    Rest: jest.fn().mockImplementation(() => ({
      get: jest.fn(),
      post: jest.fn(),
      put: jest.fn(),
      delete: jest.fn(),
    })),
  },
  // Add other parts of the API you need to mock
};

module.exports = { Shopify: mockShopify };

4. Write Tests:

In your test files, use Jest to write your test cases. Import the necessary modules and use the mocked version of the Shopify API:



const { Shopify } = require('@shopify/shopify-api');

describe('Shopify API tests', () => {
  it('should validate auth callback', async () => {
    Shopify.Auth.validateAuthCallback.mockResolvedValueOnce({ /* mock response */ });

    const result = await Shopify.Auth.validateAuthCallback(/* params */);

    expect(result).toEqual({ /* expected response */ });
    expect(Shopify.Auth.validateAuthCallback).toHaveBeenCalledWith(/* params */);
  });

  it('should perform a REST API get request', async () => {
    const mockResponse = { body: { /* mock data */ } };
    Shopify.Clients.Rest.mockImplementation(() => ({
      get: jest.fn().mockResolvedValueOnce(mockResponse),
    }));

    const client = new Shopify.Clients.Rest(/* params */);
    const response = await client.get(/* params */);

    expect(response).toEqual(mockResponse);
    expect(client.get).toHaveBeenCalledWith(/* params */);
  });

  // Add more test cases as needed
});

5. Run Tests:

Execute your tests using Jest:

npm test

By following these steps, you can effectively test the @shopify/shopify-api package with Jest, ensuring your application logic is correctly interacting with the Shopify API.
