Uses the {covr} package to produce unit test coverage reports. Uses the {testhat} package to run all unit tests in tests/testthat directory.

Usage

covr_r(
  source_files = list.files("app", pattern = "\\.[rR]$", full.names = TRUE, recursive =
    TRUE),
  test_files = list.files("tests/testthat", pattern = "^test-.*\\.R", full.names =
    TRUE, recursive = TRUE),
  line_exclusions = NULL,
  function_exclusions = NULL
)

Arguments

source_files

Character vector of source files with function definitions to measure coverage. Defaults to all .R files in the app tree.

test_files

Character vector of test files with code to test the functions. Defaults to all test files in tests/testthat with the test-<name>.R filename pattern.

line_exclusions

Value

A covr coverage dataset.
