Hi

[thorny tangle]

hi @worn ridge

I'm going to write unit tests for my developed function that uses the Stripe service in Node.js, and I'm using the Jest framework for unit testing. However, when I try to mock it, I'm getting an "undefined" error for Stripe.

?

// Import the function to be tested
import { CancelSubscriptionAPI } from '../../controllers/stripe/stripe-subscription';
import dotenv from "dotenv";
dotenv.config();

describe('CancelSubscriptionAPI', () => {
let req;
let res;

beforeEach(() => {
req = {
body: {
sub: 'some_sub_id',
subscriptionId: 'sub_12345',
},
};
res = {
status: jest.fn().mockReturnThis(),
json: jest.fn(),
};
});

afterEach(() => {
jest.clearAllMocks();
});

it('should return status 200 if subscription retrieval is successful', async () => {
// Mock stripe.subscriptions.retrieve
jest.mock('stripe'); // Mock only the subscriptions functionality
const stripe = require('stripe'); // Import the mocked Stripe library

console.log('stripe=', stripe);

const mockSubscription = {
  id: 'sub_12345',
  customer: 'cus_abc123',
};
(stripe.subscriptions.retrieve as jest.Mock).mockResolvedValue(mockSubscription);

// Call the function
await CancelSubscriptionAPI(req, res);

expect((stripe.subscriptions.retrieve as jest.Mock)).toHaveBeenCalledWith('sub_12345');
expect(res.status).toHaveBeenCalledWith(200);
expect(res.json).not.toHaveBeenCalled(); // No JSON data sent on success

});

// Add more test cases as needed
});

this is my unit test

And error i get

export const CancelSubscriptionAPI = async (req, res) => {
const { sub, subscriptionId } = req.body;
try {
const subs= await stripe.subscriptions.retrieve(subscriptionId);

return res.status(200);

} catch (err) {

return res.status(402).json({
  status: "FAILED",
  error: err.message,
});

}

};
This is my function need to be test.
