RStudio addins for several common testing-related tasks during package development, such as switching between a source file and an associated test file, or running unit tests in a single test file (hotkeyable in RStudio!). testthis also provides utility function to manage tests in subdirectories of the test/testthis directory.
For details please refer to the README
Testthis uses usethis::proj_get() to detect project root of the current
working directory. You can override the project root with
usethis::proj_set().
Package options can be set with options(). You can add options() to
your .Rprofile to make them permanent across sessions.
testthis.sepDefault separator to use when creating test files with
test_skeleton(). Defaults to _, must be either _ or -; i.e whether
you want your files to be named test_foofunction.R or test-foofunction.R
testthis.integration_tests_path, testthis.acceptance_tests_path,
testthis.manual_tests_pathDefault paths used by the functions
testthis::use_integration_tests(), testthis::test_integration(), etc...
test_this tags are special comments that modify the behaviour of the
functions supplied by this package. They are of the form #* @tag <value>.
Please not that only some test_this tags really require a <value>.
Valid tags for script files in the /R/ dir (pkg/R/*.R)
@testfile <filename>: manually specify associated test file. Should
usually start with test_. This is used by test_this(), lest_this() and
open_testfile().
Valid tags or test files (pkg/tests/testthat/test_*.R)
@testing <functionname>: mark functionname as tested.
Should usually go next the associated test_that() call. This is used by
test_coverage().
