Testing CKI Builds

How to test CKI builds and submit results

Ready for test messages

CKI sends ready for test messages after a kernel is built and after CKI functional testing completes. This is meant to be used to trigger testing in specialized labs for testing that is not feasible to onboard into CKI (e.g. testing that requires a controlled environment or special hardware).

Ready for test details

Messages are sent to /topic/VirtualTopic.eng.cki.ready_for_test. All labs involved in extra testing will be notified if the topic is changed.

Onboarded labs can filter specific messages they are interested in. Some examples include:

  • Filtering on modified files to only test changes to their subsystem
  • Filtering on system/os to only test changes to specific release
  • Filtering on cki_finished == false to run testing in parallel
  • Filtering on cki_finished == true && status == 'success' to e.g. only run performance tests if CKI functional testing passed
  • Filtering on nonempty patch_urls to only test proposed changes instead of already merged ones
  • A combination of the above

Results messages

Test results should be sent back via UMB to /topic/VirtualTopic.eng.cki.results. Results must be sent in KCIDB v4 format, which has a detailed schema documented by kcidb-io.
