How to improve app structure for automated testing?

We're looked at alternatives to the usual MVC paradigm to improve testability of the code.

Some suggested to use MVP (Model-View-Presenter) but that seems like just moving some logic from the view layer to the presenter layer.

Some use MVVM, VIPER also came up.

Question is, which of these, if any are best for improving the testability of android and iOS apps? Or a new solution perhaps.
