# Here we provide a way how a role can add its custom command to be run. Such
# extra command is run at the end of each testenv run and is driven by
# environment variables. Involved environment variables are:
#
#   LSR_TEXTRA_DEPS
#     - contains dependency needed by commands to run smoothly; if more than
#       one dependency is needed, use external file together with '-r' option
#       (see PEP 508)
#
#   LSR_TEXTRA_DIR
#     - directory to which to cd
#
#   LSR_TEXTRA_CMD
#     - custom command to be run
#
# Example: `network` system role need to run `./tests/ensure_non_running_provider.py`
#          to check for the existence of `*_provider.yml` playbooks. The script
#          is run in Python 3.6.
#
#          To make this possible, we add to `.travis/config.sh` a snippet:
#
#              export LSR_TEXTRA_DEPS='PyYAML'
#              export LSR_TEXTRA_DIR='tests'
#              export LSR_TEXTRA_CMD='./ensure_non_running_provider.py'
