-// TestBindToDataset verifies the functionality of the BindToDataset method in the JuiceFSEngine struct.
-// It initializes test datasets and JuiceFS runtime objects, creates a fake client, and invokes the method.
-// The test checks if the dataset's status is updated correctly to the expected bound phase, with cache states
-// and HCFS status properly reflected. If the function does not produce the expected results, it logs an error.

-// Parameters:
-// - t *testing.T: The testing framework's instance used to report errors and manage test execution.
-//
-// Returns:
-// - This function does not return a value but reports test failures using t.Errorf().
