# Run RAS test: Unsafe Shutdown Local. | |
# | |
# This workflow is run on 'self-hosted' runners. | |
# | |
# RAS tests require a different approach compared to the standard tests - they need to | |
# reboot the runner during the test. Normally, rebooting and continuing the job on GHA | |
# is not possible, due to losing connection with the runner. To work around this issue, | |
# an additional runner (not connected to the GH) runs the tests instead. | |
# | |
# The general idea of the solution is: | |
# - First platform [self-hosted runner] functions as the controller [ras_controller], | |
# - Second platform functions as the test runner [ras_runner], | |
# - The workflow launches its steps on the controller, | |
# - The controller will then run an ansible playbook on the second platform [ras_runner], | |
# with options provided by the workflow, | |
# - The test runner follows the steps given by the controller, | |
# running the tests in the process and providing results as output, | |
# - The controller gathers this output and prints it in GHA job. | |
# | |
# The only drawback of this idea is that workflow would always finish successfully. | |
# The solution was added as an additional step, at the end of the workflow, parsing the output. | |
# | |
# More detailed information about the ansible playbook and tests themselves can be found in: | |
