| Nowadays, DI (Dependency Inversion) is one of the widely used design
pattern.
It provides several benefits, such as (1) loose coupling between
component (2) effective and easy testing (component testing or unit
testing)
What are the drawbacks or di vantages of using DI?
Thank you very much for your answer in advance.

The "divantage" is that it is merely a tedious workaround for an
appearent weakness in mainstream OOPLs, namely the confusion and
muddling of subclassing and subtyping. In particular, languages with
structural type systems provide the benefits you cite more or less for
free.
