source_file {testthat} | R Documentation

## Source a file, directory of files, or various important subsets

### Description

These are used by `test_dir()` and friends

### Usage

    source_file(path, env = test_env(), chdir = TRUE,
      encoding = "unknown", wrap = TRUE)

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

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

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

    source_test_teardown(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.
