| # Run all internal tests, archive result to cloud storage. |
| # In the continuous operation flow we have a tester continuously checking |
| # a specific cloud storage location for a file with a git hash. |
| # If the file is there, the tester will remove the file, and add another |
| # file stating that this is now being run. After successfully running, |
| # the tester will add yet another file, and remove the last one. |
| # Complete flow with states: |
| # 1: |
| # BOT: |
| # Add file READY_FOR_TESTING (contains git hash) |
| # Wait until file TESTING_COMPLETE exists (contains git hash) |
| # Timeout if no progress for RUN_TIMEOUT |
| # Cleanup READY_FOR_TESTING and TESTING |
| # 2: |
| # TESTER: |
| # Replace file READY_FOR_TESTING by TESTING (contains git hash) |
| # Run tests for git hash |
| # Upload commit specific logs if failures |
| # Upload git specific overall status file (failed or succeeded) |
| # Replace file TESTING by TESTING_COMPLETE (contains git hash) |
| # 3: |
| # BOT: |
| # Read overall status |
| # Delete TESTING_COMPLETE |
| # Exit based on status |
