test_file {testthat}

Run tests in a single file

Description

Helper, setup, and teardown files located in the same directory as the test will also be run. See vignette("special-files") for details.

Usage

test_file(
  path,
  reporter = default_compact_reporter(),
  desc = NULL,
  package = NULL,
  ...
)

Arguments

path

Path to file.

reporter

Reporter to use to summarise output. Can be supplied as a string (e.g. "summary") or as an R6 object (e.g. SummaryReporter$new()).

See Reporter for more details and a list of built-in reporters.

desc

Optionally, supply a string here to run only a single test (test_that() or describe()) with this description.

package

If these tests belong to a package, the name of the package.

...

Additional parameters passed on to test_dir()

Value

A list (invisibly) containing data about the test results.

Environments

Each test is run in a clean environment to keep tests as isolated as possible. For package tests, that environment inherits from the package's namespace environment, so that tests can access internal functions and objects.

Examples

path <- testthat_example("success")
test_file(path)
test_file(path, desc = "some tests have warnings")
test_file(path, reporter = "minimal")
