Non-nullable field '_form' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Nullability in constraints for type parameter 'T' of method 'MockJsStorageService.StoreItem<T>(string, StorageLocation, T)' doesn't match the constraints for type parameter 'T' of interface method 'IJsStorageService.StoreItem<T>(string, StorageLocation, T)'. Consider using an explicit interface implementation instead.

Nullability in constraints for type parameter 'T' of method 'MockJsStorageService.RetrieveItem<T>(string, StorageLocation, T)' doesn't match the constraints for type parameter 'T' of interface method 'IJsStorageService.RetrieveItem<T>(string, StorageLocation, T)'.
