Tests to check stacklight

Prerequisites:

Code requirements:

Install requirements with pip install -r requirements.txt

Build and install as python package

Build dist with next command:

python setup.py sdist
# or:
tox -e build

Run install on target machine:

pip install dist/stacklight_tests-1.0.tar.gz --process-dependency-links

where --process-dependency-links flag is necessary.

Installing dependencies and system packages

To install system packages run:

apt install -y build-essential libssl-dev libffi-dev python-dev libyaml-dev python-dev python-pip

Create and activate virtualenv:

pip install virtualenv
virtualenv ../venv-stacklight-test
source ../venv-stacklight-test/bin/activate

Install dependencies, if you aren't using this project as package:

pip install -r requirements.txt

Run tests

In case of using MK2x it worth generating config from mk env to run tests:

PYTHONPATH=".:$PYTHONPATH" python stacklight_tests/config/mk_config.py

or run:

stl-tests gen-config-mk

if you have stacklight_tests installed.

To view initial tests in test_alerts.py just type 'pytest'. They are using default settings from deployment. Later it is going to be configured.

Notes

The difference between our fixture destructive with its method .append(callable_recovery) usage and pytest built-in request with method .addfinalizer(callable) is in post conditions: destructive makes his work only on fail, finalizer makes it in any case. So, use destructive, when reverting of something broken is made in test itself, and finalizer when it is not.
