In this session, we'll peel back the layers, unraveling the magic of test runners behind the scenes.

Join me as we recreate the Node.js test runner from scratch, providing insights into how Node.js utilizes asyncHooks, one of the most powerful APIs, to track async contexts and report errors.

Get ready for a hands-on exploration that will demystify the core functionalities of test runners.

Outline:

Imagine understanding the inner workings of how your tests are executed. In this session, I'll go beyond the surface and rebuild a simpler version of the Node.js test runner, unveiling the power of asyncHooks.

Together, we'll explore how asyncHooks, one of the most potent APIs in Node.js, tracks async contexts and reports errors.

Follow along as I demonstrate step-by-step the process of recreating a test runner, providing valuable insights into the mechanisms that ensure the reliability of your tests.

Takeaways:
- Understanding Test Runner Internals
- Power of asyncHooks
- Building a Test Runner from Scratch
- Error Reporting in Asynchronous Environments
