    • 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
  • support cross-compilation? 'yes

  • 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.

Run artifact handling

Does your test system:

  • store run artifacts yes
    • in what format? raw files
  • put the run meta-data in a database? yes
    • if so, which database? anything supported by sqlalchemy
  • parse the test logs for results? yes
  • convert data from test logs into a unified format? no
    • if so, what is the format?
  • 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?
