What comments do you want to add?
TestUpdateCacheOfDataset tests the UpdateCacheOfDataset function of JuiceFSEngine.
It verifies if the Dataset's cache states are correctly updated based on the associated JuiceFSRuntime's status.
The test sets up a mock Dataset and JuiceFSRuntime, then triggers the cache update and checks if the Dataset's
CacheStates field matches the expected status from the Runtime. It validates the synchronization between
Runtime status and Dataset cache states in the Kubernetes cluster.
