Being able to use asynchronous functions in your tests could be useful, for example, when you're querying your database asynchronously. Imagine you want to test sending requests to your FastAPI application and then verify that your backend successfully wrote the correct data in the database, while using an async database library.

### Bug or Regression

- Correct event registration for multiple scheduler plugins; this fixes a potential significant delay in re-queueing unschedulable pods. ([#109466](https://github.com/kubernetes/kubernetes/pull/109466), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling and Testing]
