# 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
