+// TestGetFSInfoFromConfigMap is a unit test for the GetFSInfoFromConfigMap function.
+// It verifies that the function correctly retrieves file system information from a ConfigMap.
+// 
+// The test sets up a fake Kubernetes client with a predefined ConfigMap and Dataset,
+// then calls GetFSInfoFromConfigMap and compares the returned metadata with expected values.
+//
+//  Steps:
+// 1. Create a fake ConfigMap containing FS configuration data.
+// 2. Create a fake Dataset associated with the ConfigMap.
+// 3. Use a fake client to simulate interactions with the Kubernetes API.
+// 4. Call GetFSInfoFromConfigMap with the dataset's name and namespace.
+// 5. Validate that the returned metadata matches the expected values.
+//
+// If the function does not return the correct values, the test fails with an error message.
