package_coverage() vs minimal package (on Windows?)

[jonthegeek]

In today's workshop, I made the minimal package available here.

When I check coverage, I get this error:

[main 15:40:52] > devtools:::test_coverage()
ℹ Computing test coverage for workshoppractice
Error in `-stats$Relevant`:
! invalid argument to unary operator
Backtrace:
    ▆
 1. └─devtools:::test_coverage()
 2.   └─covr::report(coverage)
 3.     └─covr:::to_report_data(x)
 4.       └─covr:::sort_file_stats(res$file_stats)
 5.         └─base::order(as.numeric(sub("%", "", stats$Coverage)), -stats$Relevant)

I found that it's specifically here:

coverage <- covr::package_coverage()
length(coverage)
#> 0

If I add a line to check_installed.R above the definition of the function (ie, an irrelevant line), coverage has length 3. This is probably low priority since it goes away as soon as I do something real, but it was weird.

To officially log it: someone mentioned they saw the same behavior on mac, so it isn't a windows-only thing. Could be related to mocking and/or snapshots.

I am getting the same error message when developing a toy package on macOS.
