Makes sense to me! I'm sad we had to do this but CRAN has left us no choice

[bburns632]

During testing, even though logs indicate the "on CRAN" route was taken, packages are still loaded. Seemingly, the setup and teardown testthat files are to blame even though they fall outside of the specified filter for tests on cran.

By removing these files, we should see no issues on CRAN or R CMD check locally. However, devtools::test() will fail in the local terminal. For now, I think that is acceptable.
