biocViews::recommendBiocViews can't find DESCRIPTION file during unit tests

[bschilder]

Hi there,

I'm trying to incorporate the biocViews::recommendBiocViews function into of my my package's functions: rworkflows::infer_biocviews:
https://github.com/neurogenomics/rworkflows/blob/master/R/infer_biocviews.R

However when I go to run unit tests with it using testthat, it can't find the DESCRIPTION file. My usual hacks for getting around this directory-specific issue (e.g. setwd("../../") aren't working either.
https://github.com/neurogenomics/rworkflows/blob/master/tests/testthat/test-infer_biocviews.R

So my question is twofold:

1. Do you know of a way around this issue of finding the DESCRIPTION file during tests more generally (couldn't find any explicit examples in your test folder)?
2. Could you possibly expose to users the step in which the DESCRIPTION file is imported via a new argument (named something like d or description that expects an object of the class "description")? I have some other functions for (usually) more robustly finding and importing the DESCRIPTION file across a wider variety of scenarios (rworkflows::get_description). Specifically, this step:
   

   biocViews/R/recommendBiocViews.R

   Line 108 in 58eda22

   dcf <- read.dcf(descr_file, c("Description", "Title", "Package","biocViews"))

Many thanks in advance!,
Brian
