Implementing Angular web app health check service

[OlegKon]

Hi,

We have an Angular web app (with a backend in Java SpringBoot).

Need to build a health check service, which tests that all its services are up and working and shows the status to the users.

Is it possible to build that service as a unit test, which calls several other unit tests (testing a few existing web services - get/post) using Jasmine/Karma or Playwright? Can we integrate that in the app, so user clicks a button, it runs and returns/displays the result in the app as binary or a list of binaries (per service)?

If not, what would be a better approach?

Please advise. Any code sample?

Any help is very appreciated, 

Oleg.
