How to mock/stub methods in Elixir library Ecto/Repo?

Tell me please how to mock/stub methods of Repo module for my tests?

For ex.:

link = Repo.get_by(Link, short_url: url)
db_count = Repo.aggregate(Link, :count, :id)

I need that Repo.aggregate returns 10000000000 for my tests. The same with Repo.get_by .

How to do it?

And what is the best approach for module isolation in tests in Elixir?

Thanks!
