test_dir {testthat} | R Documentation

## Run all of the tests in a directory.

### Description

Test files start with `test` and are executed in alphabetical order (but they shouldn't have dependencies). Helper files start with `helper` and loaded before any tests are run.

### Usage

    test_dir(path, filter = NULL, reporter = "summary", env = test_env(), ...)

### Arguments

`path` | path to tests
`filter` | If not `NULL`, only tests with file names matching this regular expression will be executed. Matching will take on the file name after it has been stripped of `"test-"` and `".R"`.
`reporter` | reporter to use
`env` | environment in which to execute test suite.
`...` | Additional arguments passed to `grepl` to control filtering.

### Value

the results as a "testthat_results" (list)
