Regular automated checks of your module code help ensure your module can be run by others and that no errors are introduced when you make a change to your code. Users hosting module code in GitHub repositories can take advantage of free GitHub Actions minutes to automatically run their module.
NOTE: Long-running or memory-intensive code should not be run. GitHub actions limits code execution.
Since we encourage all module authors to maintain a high-level
overview of their module in a .Rmd
file, this can be used
to demonstrate use of the module, as as well as test that the module can
be run without error. By default, the automated testing of the module is
done by running (i.e., rendering) the module’s
.Rmd
file.
When creating a new module, simply specify
useGitHub = TRUE
to generate the necessary GitHub Actions
configuration file.
For existing modules, use
use_gha(name = 'moduleName', path = 'modulePath')
to add
the GitHub Actions testing workflow.
You can modify your module’s workflow file
(.github/workflows/render-module-rmd.yaml
) to suit your
specific needs.
Some packages may require installation of additional system
dependencies. The workflow file contains a section named Install
GDAL and other dependencies, which can be updated to include
additional system packages. To determine which additional packages need
to be installed, use remotes::system_requirements
. For
example, to determine the system dependencies required for the
usefulFuns
package (from GitHub), get the package code and
determine what additional system packages need to be installed.
$ git clone https://github.com/PredictiveEcology/usefulFuns
$ cd usefulFuns
$ Rscript -e 'remotes::system_requirements("ubuntu", "18.04")'

Note that this does not currently capture system dependencies from
packages in the Remotes
field of the
DESCRIPTION
file. However, a separate call to those
packages will get them.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
