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!

Here's an example from https://github.com/gialib/ex_mock readme:
defmodule MyTest do
use ExUnit.Case, async: false
import ExMock
test "test_name" do
with_mock HTTPotion, [get: fn(_url) -> "<html></html>" end] do
HTTPotion.get("http://example.com")
# Tests that make the expected call
assert called HTTPotion.get("http://example.com")
end
end
end
