What comments do you want to add?

// TestTransformPodMetadata tests the transformation of Pod metadata (labels and annotations)
// for AlluxioRuntime components. It verifies that common metadata specified in the Runtime's
// PodMetadata is correctly applied to Master, Worker, and Fuse components, while ensuring
// component-specific metadata overrides the common settings when present.
//
// Test cases:
// 1. Set common labels and annotations:
// Verifies that labels/annotations from Runtime.Spec.PodMetadata are propagated to
// all components (Master, Worker, Fuse) when no component-specific metadata exists.
//
// 2. Set master and worker labels/annotations:
// Validates that component-specific metadata in Master/Worker PodMetadata takes precedence
// over common metadata, while Fuse uses common metadata when no Fuse-specific settings exist.
//
// The test checks if the transformed Alluxio configuration matches the expected output
// after applying the metadata transformation rules.
