package_coverage only showing cpp files, all zero percent

[jessekps]

Hi,

I used covr::report a few days ago for the first time and it worked as expected, very useful. I have since added some unit tests but I can't get package_coverage to work again. Every time I've ran it since the first time, it only returns results for cpp files, and they are always at 0%.

# run from within the package directory
> package_coverage()

I do have a tests/testthat.R file. It has not changed recently. I suspected there might be some left-over files from the first run of package_coverage but I can't find anything. Running with quiet=FALSE shows it does some compiling but it does not run any unit tests. The package builds without errors and devtools::test runs fine:

> devtools::test()

After a couple failures I updated R, re-installed all packages from Cran and tried again, no change. Do you have any pointers? If you have the time to look, the package is here: https://github.com/dexter-psychometrics/dexter
