covr file_coverage with testthat expect_snapshot

[sclewis23]

I'm trying to get coverage report for some functions not in a package but just some script files. I'm using some testthat::expect_snapshot checks . My test are sucessful but when I try to run the code coveage it says "Can't compare snapshot to reference when testing interactively" Any work arounds to run coverage ?

library(testthat)
coverage <- covr::file_coverage(source_files = "/usrfiles/shared-projects/shannon/RENV_400_PACKAGES/TESTS/temp_fn.R",
                                test_files = "/usrfiles/shared-projects/shannon/RENV_400_PACKAGES/TESTS/test-temp_fn.R")
#> Can't compare snapshot to reference when testing interactively
#> ℹ Run `devtools::test()` or `testthat::test_file()` to see changes
#> ℹ Current value:
#> WAoAAAACAAQAAAACAwAAAAAOAAAAAUAAAAAAAAAA
#> ── Skip (test-temp_fn.R:1:1): Test snapshot function ───────────────────────────
#> Reason: empty test
covr::report(coverage)
