Details

When providing a factory function to the module mocking method, the mock seems to no longer be hoisted to the top. The module is not mocked in the system under test in this case.

Reproduce Steps

App.test.tsx:

import { expect, test } from '@rstest/core';
import { render, screen } from '@testing-library/react';
import App from '../src/App';

rs.mock('../src/module', () => ({
  some: () => 'mocked',
}));

test('should render App correctly', async () => {
  render(<App />);

  const element = screen.getByRole('title');

  expect(element.textContent).toBe('mocked');
});

App.tsx:

import './App.css';

import { some } from './module';

const App = () => {
  return (
    <div className="content">
      <h1 role="title">{some()}</h1>
      <p>Start building amazing things with Rsbuild.</p>
    </div>
  );
};

export default App;

module.ts

export const some = () => 'example';

The test case will fail with the text content being "example".

You can check this repo. The mock is not working after methods are reexported.

Any updates on this? Are you able to reproduce with the clone from @YanxinTang or do you need more information?

If you urgently need this feature, you can downgrade to version 0.0.9 for now

[BastianHofmannZeiss]

Are there any updates on this? We would like to use the latest version of the library in a bigger project, but this is blocking the migration.

after internal discussion, we believe that supporting async module factory would be a complex and non-essential feature. currently, we have decided to change the way mocks are implemented, only supporting synchronous mock factories. we will resolve this issue after refactoring.

@fi3ework do you have a rough estimate on delivery of the refactor? I'm excited :)

All tests passed after upgrading to 0.6.1
