# process replay
Process replay is a regression test designed to identify any changes in the output of a process. This test replays a segment through individual processes and compares the output to a known good replay. Each make is represented in the test with a segment.
If the test fails, make sure that you didn't unintentionally change anything. If there are intentional changes, the reference logs will be updated.
Use `test_processes.py` to run the test locally.
Currently the following processes are tested:
* controlsd
* radard
* plannerd
* calibrationd
## Forks
openpilot forks can use this test with their own reference logs
To generate new logs:
`./update-refs.py --no-upload`
Then, check in the new logs using git-lfs. Make sure to also include the updated `ref_commit` file.
