+// TestGetWorkerDaemonsetName is a unit test for the getWorkerName method of the AlluxioEngine struct.
+// This test verifies that the method correctly constructs the expected worker daemonset name
+// based on the given engine name.
+// The test defines a struct `fields` containing the engine name and a test case struct
+// that includes the test case name, input fields, and the expected daemonset name.
+// The test case used:
+// - When the engine name is "spark", the expected daemonset name should be "spark-worker".
+// The test iterates through all defined cases, creates an instance of AlluxioEngine with
+// the given name, calls the `getWorkerName` method, and checks if the returned result matches
+// the expected value. If the result differs, an error message is reported.
