run-unit-test-docker.sh

#!/bin/bash -xe

# This build script is for running the Jenkins unit test builds using docker.
#
# This script will build a docker container which will then be used to build
# and test the input UNIT_TEST_PKG. The docker container will be pre-populated
# with the most used OpenBMC repositories (phosphor-dbus-interfaces, sdbusplus,
# phosphor-logging, ...). This allows the use of docker caching
# capabilities so the dependent repositories are only built once per update
# to their corresponding repository. If a BRANCH parameter is input then the
# docker container will be pre-populated with the latest code from that input
# branch. If the branch does not exist in the repository, then master will be
# used.
#
#   UNIT_TEST_PKG:   Required, repository which has been extracted and is to
#                    be tested
#   WORKSPACE:       Required, location of unit test scripts and repository
#                    code to test
#   DISTRO:          Optional, docker base image (ubuntu or fedora)
#   BRANCH:          Optional, branch to build from each of the
#                    openbmc repositories. default is master, which will be
#                    used if input branch not provided or not found
#   DOCKER_IMG_NAME: Optional, default is openbmc/ubuntu-unit-test-master with a
#                    -$BRANCH replacing -master if $BRANCH provided
#   dbus_sys_config_file: Optional, with the default being
#                         `/usr/share/dbus-1/system.conf`
#   NO_FORMAT_CODE:  Optional, do not run format-code.sh
#   EXTRA_UNIT_TEST_ARGS:  Optional, pass arguments to unit-test.py

# Trace bash processing. Set -e so when a step fails, we fail the build
set -uo pipefail
