+// TestSetupMaster tests the SetupMaster function of the AlluxioEngine.
+// It initializes a fake Kubernetes client with predefined StatefulSet and AlluxioRuntime objects,
+// then verifies whether SetupMaster correctly updates the runtime's status fields.
+// The test ensures that:
+// 1. The SetupMaster function executes without errors.
+// 2. The runtime object is correctly retrieved after execution.
+// 3. The runtime's status is properly updated, including the selector, 
+//    configuration map name, and the presence of conditions.。
