Hi again 👋 do you have more context?

[tacit dirge]

Hi actully error is realted to stripe pls look its stay cannot read property of reterive undefined

[sturdy cloud]

Where it points to your res.json variable?

[tacit dirge]

let me show u

[sturdy cloud]

Please do

[tacit dirge]

// 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
});

In above unit test where we getting res:
// beforeEach(() => {
req = {
body: {
sub: 'some_sub_id',
subscriptionId: 'sub_12345',
},
};
res = {
status: jest.fn().mockReturnThis(),
json: jest.fn(),
};
});

[sturdy cloud]

And the error was pointing to this line?
expect(res.json).not.toHaveBeenCalled(); // No JSON data sent on success

[tacit dirge]

let me retunr fresh case without this

// 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);


expect((stripe.subscriptions.retrieve as jest.Mock)).toHaveBeenCalledWith('sub_12345');

});

// Add more test cases as needed
});

now this is my test case

see the error

TypeError: Cannot read properties of undefined (reading 'retrieve')

[sturdy cloud]

Wait, are you importing our actual library, or are you mocking it? (I'm not familiar with Jest)

[tacit dirge]

mocking

can u provide me any example because i ahve research alot but not find sutiable example

[sturdy cloud]

If you aren't using our actual library, then I'm likely not familiar with what library you're using and may not be able to provide advice on how to use it. How are you mocking it, did you create your own mock library to pull in? Are you using our prebuilt stripe-mock server?
https://github.com/stripe/stripe-mock

I'm also thinking this is a typing issue, since the error seems to be a TypeError.

[tacit dirge]

might be m not sure

[sturdy cloud]

I'd recommend getting that clarity. It's going to be hard for my teammates or I to provide any guidance if you can't tell us what you're working with.

[tacit dirge]

m working with node.js and using jest for unit test

[sturdy cloud]

How are the Stripe portions handled? Are you using a library to mock those requests, is that our library? In your code I see you have this line:
const stripe = require('stripe'); // Import the mocked Stripe library
is that pulling in the full stripe library, or is that pointing to some other library within your environment?

[tacit dirge]

alreadu have

[sturdy cloud]

I know you have it, I pulled it from the code you shared, I'm asking what it does in your code

If you're pulling in our actual Stripe library, then this doesn't seem like a mock scenario at all. Which is why I'm still trying to understand what you're doing here.

[tacit dirge]

jest.mock("stripe", () => {
return jest.fn().mockImplementation(function {
return {
charges: {
create: () => "fake stripe response",
},
};
});
});
write now m trying this

[sturdy cloud]

That seems to be diving into the Jest side of things, which I'm not familiar with.
