trouble using test_path() with expect_equal_to_reference()

[jennybc]

Seems like this should work. But test_path() doesn't want to make a path that doesn't (yet) exist.

library(testthat)
dir(test_path(), pattern = "\\.rds")
#> character(0)
expect_equal_to_reference(1, "tests/testthat/one.rds")
dir(test_path(), pattern = "\\.rds")
#> [1] "one.rds"
file.remove(test_path("one.rds"))
#> [1] TRUE
dir(test_path(), pattern = "\\.rds")
#> character(0)
expect_equal_to_reference(1, test_path("one.rds"))
#> Error: `tests/testthat/one.rds` doesn't exist

I now see "An error will be thrown if the path doesn't exist." in the help file. OK. But isn't this one of the main uses for test_path()?

I agree that testing if the file exists shouldn't be the responsibility of test_path(). Removing the check and amending the documentation seems fair to me.
