To make this a little faster, we only generate locales in two of the six tests (combining them asymmetrically so that we generate locales once with and once without --copy-runtime-into, and once for each runtime we are running from), and skip checking that locales were generated correctly in the other tests.

"""
Test pressure-vessel against an out-of-band set of pre-prepared containers.
To run during build-time testing, build with
-Dtest_containers_dir=/path/to/containers, where /path/to/containers
ideally contains at least:
* pressure-vessel:
A sufficiently recent copy of pressure-vessel, used for the parts
that must run inside the container (because we cannot assume that
an arbitrary build done on the host system is compatible with the
libraries inside the container)
* steam-runtime:
An LD_LIBRARY_PATH runtime, which we use to find versions of
steam-runtime-system-info and capsule-capture-libs that can run
on the host system
* scout/files:
The Platform merged-/usr from the SteamLinuxRuntime depot
* scout_sysroot:
An SDK sysroot like the one recommended for the Docker container
and run (for example) 'meson test -v -C _build' as usual.
The same test can also be run against a version of pressure-vessel
that was built against scout:
export PRESSURE_VESSEL_TEST_CONTAINERS=/path/to/containers
./sysroot/run-in-sysroot.py --sysroot ../scout-sysroot -- \
ninja -C _build-for-sysroot
env DESTDIR="$(pwd)/_build-for-sysroot/DESTDIR" \
./sysroot/run-in-sysroot.py --sysroot ../scout-sysroot -- \
ninja -C _build-for-sysroot install
rm -fr "$PRESSURE_VESSEL_TEST_CONTAINERS/pressure-vessel"
env DESTDIR="$(pwd)/_build-for-sysroot/DESTDIR" \
./sysroot/run-in-sysroot.py --sysroot ../scout-sysroot -- \
python3.5 ./build-relocatable-install.py \
--output="$PRESSURE_VESSEL_TEST_CONTAINERS/pressure-vessel" \
--check-source-directory="$PRESSURE_VESSEL_TEST_CONTAINERS" \
--allow-missing-sources \
--srcdir="$(pwd)" --set-version "$(git describe)"
./tests/containers.py
or against the SteamLinuxRuntime depot that gets uploaded to the Steam CDN:
export PRESSURE_VESSEL_TEST_CONTAINERS=../SteamLinuxRuntime/depot
./tests/containers.py
Influential environment variables:
* AUTOPKGTEST_ARTIFACTS:
Write test artifacts to this directory (borrowed from Debian's
autopkgtest framework) instead of a temporary directory. This makes
debugging easier.
* BWRAP:
A bubblewrap executable
* G_TEST_SRCDIR:
The ./tests subdirectory of the source root, typically $(pwd)/tests
* G_TEST_BUILDDIR:
The ./tests subdirectory of the build root, typically $(pwd)/_build/tests
* PRESSURE_VESSEL_LIBCAPSULE_TOOLS:
Override the location of capsule-capture-libs etc.
* PRESSURE_VESSEL_TEST_CONTAINERS:
A complete relocatable pressure-vessel installation, including its
dependencies such as libsteam-runtime-tools
* PRESSURE_VESSEL_UNINSTALLED:
Set when running from the source/build trees
* STEAM_RUNTIME_SYSTEM_INFO:
Path to a steam-runtime-system-info executable for the host system
Please keep this script compatible with python3.4 so that it can be
run on the oldest platforms where pressure-vessel works:
SteamOS 2 'brewmaster', Debian 8 'jessie', Ubuntu 14.04 'trusty'.
