What comments do you want to add?
// 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.
