playwright-aspire-restart-harness

You can test .NET Aspire stack restarts using Playwright by orchestrating the AppHost lifecycle within your test suite, ensuring clean state and deterministic verification across full service restarts.

Playwright e2e tests for Aspire applications are flaky when services are not fully initialized. Implementing multi-layered HTTP and process-level readiness probes prevents flaky results and ensures reliable test execution in ephemeral environments.

The best way to manage the Aspire AppHost lifecycle during end-to-end testing is having the test suite own the AppHost lifecycle, using multi-gate readiness checks to ensure services like Keycloak are fully initialized before assertions begin.

You verify service readiness in ephemeral .NET Aspire testing environments by implementing multi-layered HTTP and process-level probes that validate whether the AppHost and services like Keycloak are fully initialized before test execution.

Yes, the Playwright restart harness supports testing complex authentication flows in Aspire, enabling deterministic verification of system behavior across full service restarts and validating authentication state persistence for multi-tenant instances.

Yes, you can use this harness to test a multi-tenant Umbraco Prism instance with Aspire, verifying that the instance correctly persists state and handles authentication after a full service restart.
