What is the best approach to implement global teardown with Playwright?

I have been struggling to implement a global teardown for Playwright, but I am unable to get it to execute. Despite following the guidelines provided in the documentation, the teardown function refuses to work. Although I do not have a setup command running, I fail to see how it would impact the execution of the teardown. In my configuration, I simply utilize the globalTeardown option to specify the file that needs to be executed. Below is an example snippet from the file being referenced:

async function globalTeardown(_config: FullConfig) {
    const browser = await chromium.launch();
    const context = await browser.newContext();
    const page = new CustomPage(await context.newPage());

    try{
        await context.tracing.start({ screenshots: true, snapshots: true });
        cleanUpFunc(page);

        await browser.close();
    } catch (error) {
        context.tracing.stop({ 
            path: './test-results/teardown-trace.zip',
        });
        await browser.close();
        throw("Global setup error:\n" + error);
    }

}

In the cleanUpFunc function, there will be various operations performed on the Page or CustomPage objects, which I am unable to provide specific examples for.

Due to NDA constraints, I cannot share actual code snippets, but I am willing to offer guidance through generic illustrations if necessary.

Appreciate your assistance!

It's a mystery what code you're executing, but chances are you're not waiting for cleanUpFunc.

// global-teardown.ts

async function globalTeardown() {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();

  try {;
    await context.tracing.start({ screenshots: true, snapshots: true });
    await cleanUpFunc(page);
  } catch (e) {
    console.log(`Error in globalTeardown: ${e}`);
  } finally {
    await browser.close();
  }
}

export default globalTeardown;

and configuration:

// playwright.config.ts

const config: PlaywrightTestConfig = {
  globalTeardown: "./global-teardown.ts",
}
