Add warnings to test

[jmnavarro]

Hi there!

We're working on some tests that have 3 possible outcomes: fail (green), error (red), and warning (orange).
Tests will fail only in case of errors but we want to report in the output both errors and warnings.

I've noticed there's a function for that:

testthat::testthat_warn("this is a warning")

but it's not exported, so when I invoke it, I get error Error: 'testthat_warn' is not an exported object from 'namespace:testthat'

Is there any workaround?

I'm happy to make a contribution making testthat_warn public, but first I want to make sure which is the best approach

Thanks!

Found it.

Doing a simple warning("this is a warning") is enough

So obvious!
