mockr package

[pec63]

I am using testthat to test my package.
I need to mock a function so I started to use with_mock.
First I tried mockr::with_mock in this way:
testthat(..., {..mockr::with_mock(...) }) this works without warnings or errors when I test the package; but an error occurs when I check it.

If I use testthat(..., {..with_mock(...).. }) I get warnings during package tests but everything is ok during check. The warnings are as follows:

The question is: how and where shoud I declare that I want to use mockr in order to avoid these issues?
I have tried to put library(mockr) in testthat.R but it does not work. Then I have tried to put it as the first line of the test script but it does not work ither.
Considering that the testthat::with_mock is deprecated, which is the right way to use with_mock with testthat?

THANK YOU!!!

Thanks. Do you need to add mockr to "Suggests" in DESCRIPTION?

[pec63]

I did it in Imports and it worked.

Thank you.

Looks solved, please open a new issue if not.
