# REMARK: Do not forget to enable the coverage feature for your
# project, if you are using code coverage reporting above. This can be
# done by
#
# - Navigating to the `CI/CD Pipelines` settings of your project,
# - Copying and pasting the default `Simplecov` regex example
#   provided, i.e., `\(\d+.\d+\%\) covered` in the `test coverage
#   parsing` textfield.
