Inline tests with roxygen2 using testthat or tinytest. In addition, there are a few roclets that aim at catching common documentation issues during the development cycle.

See demo package using this at roxytestdemo.

To build and install from Github run this command from within R:

remotes::install_github("mikldk/roxytest", 
                        build_opts = c("--no-resave-data", "--no-manual"))

You can also install the package without vignettes if needed as follows:

remotes::install_github("mikldk/roxytest")

Please refer to this README as well as the included manual pages as well as the vignette, all also available online at https://mikldk.github.io/roxytest/.

There are a number of roclets included:

• testthat_roclet
• tinytest_roclet
• param_roclet
• return_roclet
• examples_roclet

Please refer to the “Introduction” vignette for details on these.

To use the package in your own package you do not need to add any additional dependencies in your package’s DESCRIPTION file. Simply add the following lines to your package’s DESCRIPTION file (or any other of the roclets mentioned above):

Roxygen: list(roclets = c("namespace", "rd", "roxytest::testthat_roclet"))

In RStudio, CTRL+SHIFT+D/CMD+SHIFT+D option does not run devtools::document() but only devtools::document(roclets=c('rd', 'collate', 'namespace')) (possibly with fewer depending on the project options, but not none).

Instead, you can use devtools’ document() addin (see e.g. Rstudio documentation), and override the keyboard shortcut.
