Aggregated Health Check for Aspire AppHost: How to Detect When All Apps Are Ready?

[fortunes-guardian]

Hello everyone,

I have the following scenario:

• I use Aspire AppHost to bring up my applications and dependencies (API, database, etc.).

• Once the applications are up, stable, and have passed their respective health checks (as orchestrated by Aspire), I run E2E tests against these Aspire-hosted apps.

My question:
Is there a way to determine - externally - when all apps have passed their respective health checks, i.e., when the Aspire environment is fully stable?

Essentially, I’m looking for an aggregated health check endpoint or mechanism, so that from outside Aspire I can reliably know when it’s safe to begin sending requests and start my E2E tests.

I’m aware that with test integrations (e.g., using xUnit) it’s possible to hook into and await the Aspire Init / dispose. However, in my use case, I won’t be using xUnit or another test runner - I just need to know when the app landscape is stable for E2E testing.

Many thanks in advance for any ideas or guidance!

There's nothing built in, but this might be another case for the apphost as a resource cc @DamianEdwards 😄.

You can write code to expose an endpoint and do this (I can whip up an example later).

Thanks @davidfowl for the response. At least I know there is nothing built in at the moment. I was looking over the docs, but couldn't find anything.

For now, I just use an external script to check the health endpoint of one of my orchestrated apps. It is not ideal, and seems duplicated as Aspire is also checking the health of this app too.

If I can add a feature request or something anyway, please let me know, otherwise we can resolve this discussion.

hi @davidfowl - I saw you edited your answer.

If you have any example code to achieve this with Aspire, it would be great to see.

Thanks in advance.
