goodpractice ... covr Error in aggregate.data.frame( ... no rows to aggregate

[maurolepore]

I have a package with no functions, only datasets. I have some regression tests but I think this doesn't matter because those tests don't map to any code in R.

covr::package_coverage() passes silently, as it has nothing really to report.

I expected goodpractice::gp() to also pass, reporting whatever it has to say about my package, and maybe say nothing about my tests. Instead I get an error.

One way I hacked this is by adding a toy function in R/, e.g.:

# R/toy.R
toy  <- function() "A hack to https://github.com/MangoTheCat/goodpractice/issues/140"

And I now see the report. Here is an image:
