Downstream dependency testing

[fozy81]

This is perhaps an issue for ALA4R repo to add downstream tests, so that changes to ALA4R will not break NBN4R. And if they do break because of changes to API, downstream packages can be notified that updates need to be made. I believe there are other packages like NBN4R for particular countries using the ALA infrastructure.

Good call

one for @raymondben to think about

ALA4R probably doesn't need to explicitly add tests of downstream packages, we just need to make sure reverse dependencies still pass their own tests (as CRAN policies require already). https://github.com/yihui/crandalf may be a good way to automate this. But as NBN4R development progresses, I am sure that we'll find aspects of ALA4R that are particularly important for NBN4R but which aren't yet tested in the ALA4R tests, and which we'll thus want to add. So let's leave this issue open as a reminder.
