Buildbot survey response

Revision as of 23:08, 17 October 2018 by Krzk (talk | contribs) (Update Buildbot (and remove Gentoo specifics as they are not part of Buildbot), Buildbot is generic CI framework so some questions depend how people configure it by themself (marked as "can be configured"))

  • provide a set of existing tests? no
    • if so, how many?

build management

Does your test system:

  • build the software under test (e.g. the kernel)? yes
  • build the test software? yes
  • build other software (such as the distro, libraries, firmware)? yes

  • require a toolchain or build system for the SUT? yes
  • require a toolchain or build system for the test software? no
  • come with pre-built toolchains? no
  • store the build artifacts for generated software? yes
    • in what format is the build metadata stored (e.g. json)? internal
    • are the build artifacts stored as raw files or in a database? raw files
      • if a database, what database? everything supported by sqlalchemy

Test scheduling/management

Does your test system:

  • check that dependencies are met before a test is run?
  • schedule the test for the DUT? yes
    • select an appropriate individual DUT based on SUT or test attributes? yes (can be configured)
    • reserve the DUT? yes
    • release the DUT? yes
  • install the software under test to the DUT? yes/no (can be configured)
  • install required packages before a test is run? yes/no (can be configured)
  • require particular bootloader on the DUT? (e.g. grub, uboot, etc.) no (setups with QEMU, real hardware)
  • deploy the test program to the DUT? yes/no (can be configured)
  • prepare the test environment on the DUT? yes/no (can be configured)
  • start a monitor (another process to collect data) on the DUT? yes/no (can be configured)
  • start a monitor on external equipment? yes/no (can be configured)
  • initiate the test on the DUT? yes
  • clean up the test environment on the DUT? yes

DUT control

Does your test system:

  • store board configuration data? no
    • in what format?
  • store external equipment configuration data? no
    • in what format?
  • power cycle the DUT? no
  • monitor the power usage during a run? no
  • gather a kernel trace during a run? no
  • claim other hardware resources or machines (other than the DUT) for use during a test? no
  • reserve a board for interactive use (ie remove it from automated testing)? no
  • provide a web-based control interface for the lab? Buildbot web interface (limited, only stop test, pause the worker)
  • provide a CLI control interface for the lab? yes, Buildbot-worker

Gentoo kernel CI is working with Qemu container, real hardware is still in progress.

  • evaluate pass criteria for a test (e.g. ignored results, counts or thresholds)? yes
  • do you have a common set of result names: (e.g. pass, fail, skip, etc.) yes
  • How is run data collected from the DUT?

Buildbot-worker/Buildbot master

    • e.g. by pushing from the DUT, or pulling from a server?
  • How is run data collected from external equipment?
  • Is external equipment data parsed?
