Description

Usage

source_file(
  path,
  env = test_env(),
  chdir = TRUE,
  encoding = "unknown",
  wrap = TRUE
)
source_dir(
  path,
  pattern = "\\.[rR]$",

source_test_helpers(path = "tests/testthat", env = test_env())
source_test_setup(path = "tests/testthat", env = test_env())

Arguments

path

Path to files.

env

Environment in which to evaluate code.

chdir

Change working directory to dirname(path)?

encoding

Deprecated.

wrap

Automatically wrap all code within test_that()? This ensures that all expectations are reported, even if outside a test block.

pattern

Regular expression used to filter files.

Test files

For package code, tests should live in tests/testthat.

There are four classes of .R files that have special behaviour:

• Test files start with test and are executed in alphabetical order.

• Helper files start with helper and are executed before tests are run and from devtools::load_all().

• Setup files start with setup and are executed before tests, but not during devtools::load_all().

• Teardown files start with teardown and are executed after the tests are run.
