+// TestParseReportSummary tests the parseReportSummary method of AlluxioEngine.
+// It verifies that the method correctly parses the Alluxio report summary string
+// and extracts the cache capacity and cached size information.
+//
+// The test case includes:
+// - A mock Alluxio report summary string (mockAlluxioReportSummaryForParseReport)
+// - Expected cacheStates output with cacheCapacity and cached values
+//
+// The test compares the parsed output with expected values and reports any discrepancies.
+// This ensures the parsing logic handles the Alluxio report summary format correctly.
