# Run Openstack unit tests in lxc container by installing deps from package
# instead of using the repo requirements file which is often out of step.
#

# NOTE: this needs to be run as two parts. First create the container and
#       drop into bash prompt. Then execute the rest inside the container.

export SERIES=trusty
export OS_RELEASE=mitaka
export OS_PROJECT=nova
export GIT_BRANCH=${OS_RELEASE}-eol  # could also be stable/$OS_RELEASE or just master

# Create container

lxc launch ubuntu:${SERIES} ${SERIES}-${OS_RELEASE}-ut
lxc exec ${SERIES}-${OS_RELEASE}-ut bash

# Now (that you are inside the container back prompt) execute the following inside the container

# install apt cache if you have one e.g.
#cat << EOF > /etc/apt/apt.conf.d/99-local-apt-cache
#Acquire::http::Proxy "http://my.apt.cache:3142";
#Acquire::https::Proxy "http://my.apt.cache:3142";

# now you can run specific tests e.g.
tox -epy27 --sitepackages nova.tests.unit.network.test_manager.NetworkManagerNoDBTestCase.test_release_fixed_ip_no_mac

# if tox doesn't work you can try running it manually:
rm -rf .testrepository
testr init
TEMP_REZ=`mktemp -t`
testr run --subunit --parallel tests.unit| tee $$TEMP_REZ | subunit2pyunit
rm -f $TEMP_REZ

#NOTE: the debian package disables some tests so if you run them all you might get some errors that would not occur during a debian package build run of the same tests.

# Here are some examples of patches i had to add to get things working:

# mitaka
git apply ~/nova-13.1.4/debian/patches/disable-websockify-tests.patch

# ocata
