[Bug]: Can't export extended test object (@playwright/experimental-ct-react)

[Thomas-Haider]

Version

1.43.1

Steps to reproduce

create a test and past following code:

import React from 'react';
import { test as base, expect } from '@playwright/experimental-ct-react';
import { Locator, Page } from '@playwright/test';

interface BaseTestTryoutOption {
  author: string;
}
export class TodoPage {
  private readonly inputBox: Locator;
  private readonly todoItems: Locator;

  constructor(public readonly page: Page) {
    this.inputBox = this.page.locator('input.new-todo');
    this.todoItems = this.page.getByTestId('todo-item');
  }
}

export type TryoutFixture = {
  todoPage: TodoPage;
};

// typescript does not let me export the test object
export const test = base.extend<BaseTestTryoutOption & TryoutFixture>({
  author: undefined,
  todoPage: async ({ author, page, mount }, use) => {
    console.log(author);
    const todo = new TodoPage(page);
    await use(todo);
  },
});

test('basic test', async ({ page, mount }) => {
  const comp = await mount(<div data-testid={'tryout'}>hello world</div>);

  await expect(page.getByTestId('tryout')).toHaveText('hello world');
});

Expected behavior

i would expect to export the test object from the file and reuse in other test files. Check out the code reproduction code above for more details.

Actual behavior

as soon as i add the export to the test object i receive the following error:

I was not able to reproduce with a fresh React/Playwright CT project. Could you provide us a reproduction which we can run locally?

[Thomas-Haider]

Sure, will try to find some time today or at latest i will send it on Friday :)
