  REST base packages:

  $ pip install -U requests
  $ pip install -U robotframework-requests
  $ pip install -U robotframework-httplibrary
  

  SSH and SCP base packages: For more detailed installation instructions see robotframework-sshlibrary

  $ pip install robotframework-sshlibrary

  Installing tox:

  $ pip install -U tox
  

If using Python 3.x, use the corresponding pip3 to install packages.

OpenBMC Test Development

These documents contain details on developing OpenBMC test code and debugging.

• MAINTAINERS: OpenBMC code maintainers information.
• CONTRIBUTING.md: Coding guidelines.
• REST-cheatsheet.md: Quick reference for some common curl commands required for testing.
• README.md: Web UI setup reference.
• Tools.md: Reference information for helper tools.

Testing Setup Steps

To verify the installation setup is completed and ready to execute.

• Download the openbmc-test-automation repository:

  $ git clone https://github.com/openbmc/openbmc-test-automation
  $ cd openbmc-test-automation
  

• Execute basic setup test run:

  $ robot -v OPENBMC_HOST:xx.xx.xx.xx templates/test_openbmc_setup.robot
  

  where xx.xx.xx.xx is the BMC hostname or IP.

Test Layout

There are several sub-directories within the openbmc-test-automation base which contain test suites, tools, templates, etc. These sub-directories are classified as follows:

tests/: Contains the general test cases for OpenBMC stack functional verification.

extended/: Contains test cases for boot testing, network testing, code update testing etc.

systest/: Contains test cases for HTX bootme, IO storage and EEH testing.

xcat/: Contains test cases for XCAT automation.

gui/: Contains test cases for web UI and security scanning tool automation.

mnfg/: Contains test cases for factory reset (DHCP mode) and PGOOD testing.

network/: Contains test cases for network testing.

snmp/: Contains test cases for SNMP (Simple Network Management Protocol) configuration testing.

openpower/ras/: Contains test cases for RAS (Reliability, Availability and Serviceability) for an OpenPOWER system.

openpower/secureboot/: Contains test cases for secure boot testing on a secure boot feature enabled OpenPOWER system only.

tools/: Contains various tools.

templates/: Contains sample code examples and setup testing.

test_list/: Contains the argument files used for skipping test cases (e.g "skip_test", "skip_test_extended", etc.) or grouping them (e.g "HW_CI", "CT_basic_run", etc.).

Redfish Test Layout

OpenBMC is moving steadily towards DTMF Redfish, which is an open industry standard specification and schema that meets the expectations of end users for simple, modern and secure management of scalable platform hardware.

redfish_test: Contains test cases for DMTF Redfish-related feature supported on OpenBMC.

Quickstart

To run openbmc-automation first you need to install the prerequisite Python packages which will help to invoke tests through tox (Note that tox version 2.3.1 or greater is required) or via Robot CLI command.

Robot Command Line

• Execute all test suites for tests/:

  $ robot -v OPENBMC_HOST:xx.xx.xx.xx  tests
  

• Execute a test suite:

  $ robot -v OPENBMC_HOST:xx.xx.xx.xx  tests/test_basic_poweron.robot
  

• Initialize the following environment variables which will be used during testing:

  $ export OPENBMC_HOST=<openbmc machine ip address>
  $ export OPENBMC_PASSWORD=<openbmc password>
  $ export OPENBMC_USERNAME=<openbmc username>
  $ export OPENBMC_MODEL=[./data/Witherspoon.py, ./data/Palmetto.py, etc]
  $ export IPMI_COMMAND=<Dbus/External>
  $ export IPMI_PASSWORD=<External IPMI password>
  

• For QEMU tests, set the following environment variables as well:

  $ export SSH_PORT=<ssh port number>
  $ export HTTPS_PORT=<https port number>
  

• Run tests:

  $ tox -e tests
  

• How to run individual test:

  One specific test:

  $ tox -e default -- --include Power_On_Test  tests/test_basic_poweron.robot
  

  No preset environment variables, default configuration for all supported systems:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- tests
  

  No preset environment variables, one test case from a test suite:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- --include Power_On_Test tests/test_basic_poweron.robot
  

  No preset environment variables, the entire test suite:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- tests
  

  No preset environment variables, the entire test suite excluding test cases using argument file:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- --argumentfile test_lists/skip_test tests
  

  Exclude test list for supported systems:

  Palmetto:  test_lists/skip_test_palmetto
  Witherspoon:  test_lists/skip_test_witherspoon
  

• How to run CI and CT bucket test:

  Default CI test bucket list:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- --argumentfile test_lists/HW_CI tests
  

  Default CI smoke test bucket list:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- --argumentfile test_lists/CT_basic_run tests
  

• Run extended tests:

  For-loop test (default iteration is 10):

  $ robot -v OPENBMC_HOST:x.x.x.x -v OPENBMC_SYSTEMMODEL:xxxxxx -v ITERATION:n -v LOOP_TEST_COMMAND:xxxxxx extended/full_suite_regression.robot
  

  Example using tox testing a test suite for 5 iterations "witherspoon":

  OPENBMC_HOST=x.x.x.x  LOOP_TEST_COMMAND="tests/test_fw_version.robot" ITERATION=5 OPENBMC_SYSTEMMODEL=witherspoon tox -e witherspoon -- ./extended/full_suite_regression.robot
  

Jenkins jobs tox commands

• HW CI tox command:

  $ OPENBMC_HOST=x.x.x.x tox -e default -- --argumentfile test_lists/HW_CI tests
  

Code Update

Currently supported BMC and PNOR update formats are UBI and non-UBI. For code update information, please refer to code-update.md

• UBI Format *

  For BMC code update, download the system type *.ubi.mdt.tar image from https://openpower.xyz/job/openbmc-build/ and run as follows:

  $ cd extended/code_update/
  $ robot -v OPENBMC_HOST:x.x.x.x -v IMAGE_FILE_PATH:<image path>/obmc-phosphor-image-witherspoon.ubi.mtd.tar --include REST_BMC_Code_Update  bmc_code_update.robot
  

  For host code update, download the system type *.pnor.squashfs.tar image from https://openpower.xyz/job/openpower-op-build/ and run as follows:

  For Witherspoon system:
