Location of tests file in an R package

Question

If I have tests/testhat/testhat.R, devtools::test() finds it and runs it, but covr:package_coverage() and R CMD check does not find it.

If I have it as tests/testhat.R, devtools::test() doesn't find it but covr:package_coverage() and R CMD check does.

What's the best way to do this?

R 4.0.0; testthat 2.3.2; covr 3.5.0

Answer 1

Your directory structure of the test folder should look like this:

.
├── testthat
│   ├── test-1.R
│   ├── test-2.R
│   ├── test-3.R
│   ├── test-4.R
│   └── test-5.R
└── testthat.R

And testthat.R contains

library(testthat)
library(mypackage)

test_check("mypackage")

This works with R CMD check, covr and devtools::check().
