What comments do you want to add?
// TestUpdateDatasetStatus is a test function that verifies the behavior of the UpdateDatasetStatus method in the JuiceFSEngine.
// It tests the function with different dataset phases (Bound, Failed, None) and ensures that the dataset status is updated correctly.
// The function creates a fake client with test datasets and runtime objects, then calls UpdateDatasetStatus with each phase.
// It checks if the dataset status matches the expected result after each update.
// If any of the checks fail, the test will report an error.
