# Htmx and Playwright Tests in C#

**[Khalid Abuhakmeh](https://daily.dev/sources/khalidabuhakmeh)** · 2 min read · 0 upvotes · 0 comments

## Summary

A practical guide to reliably testing HTMX-powered ASP.NET Core applications with Playwright in C#. The key technique involves hooking into the `htmx:afterSettle` lifecycle event to emit a console message, then using Playwright extension methods (`RegisterHtmxLifecycleListener` and `WaitForHtmx`) to wait for that signal before asserting page state. This eliminates flaky timing issues caused by arbitrary delays and makes tests resilient to front-end and back-end implementation changes.
