test_path: Locate a file in the testing directory

In r-lib/testthat: Unit Testing for R

Locate a file in the testing directory

Description

Many tests require some external file (e.g. a .csv if you're testing a data import function) but the working directory varies depending on the way that you're running the test (e.g. interactively, with devtools::test(), or with ⁠R CMD check⁠). test_path() understands these variations and automatically generates a path relative to tests/testthat, regardless of where that directory might reside relative to the current working directory.

Usage

test_path(...)

Arguments

...	Character vectors giving path components.

Value

A character vector giving the path.

Examples

## Not run: 
test_path("foo.csv")
test_path("data", "foo.csv")

## End(Not run)
