OpenStackTests

This repositroy contains Openstack tests based python3.

Configuration

You need to install the requirements.

$> pip3 install -r requirements.txt

or with pip.

$> pip3 install git+https://github.com/deNBI/OpenStackTests@master

$> pip3 install git+https://github.com/deNBI/OpenStackTests@dev

Before you can start the tests you have to set some configurations.
All tests require the config.yml. The more complex tests also require the complex_test.yml

Basic-Test

There are some basic tests:

endpoint_test.py

The endpont_test sends an HTTP OPTIONS request to a specific Url of a service like glance. If the returning status code is not equal than 5xx, the test was successful You can see all avaiable services with the command:

$> python3 endpoint_test.py --help

also if you would want to test all avaiable endpoints one after the other you can just use:

$> python3 endpoint_test.py

if you want to test one specific endpoint use:

$> python3 endpoint_test.py glance

create_and_delete_image.py

The create_and_delete_image test goes through the following steps:

Downloads the actual cirros image
Uploads the cirros image
Deletes the image

If the image was uploaded and deleted without errors the test was succesfull

Complex-Test

The complex test needs beside the config.yml also the complex_test.yml
The complex_test.py goes through the following steps::

Creates a network,subnet and a router connected to a specific network
Start an instance using the default image(cirros)
Assign a floating ip to the instance
Login into the instance and try connect to google
Logout
Stop and Delete the Instance
Delete network, subnet and route

ACL Settings in OpenStack

We have to figure out how to set ACL settings for OpenStack in order to use the OpenStack usage API.

Release

We need to do the following steps in order to release:

PR into master
Allow to install with pip
Description how to install and run.
Make it public
Announce it in Rocket Chat.

Basic Tests

Basic Tests should be created according to:
https://docs.google.com/document/d/1c5nJczosBY-_QWhaHs8BtJtyTVi7Q3me2oxWh_1xhbo/edit?usp=sharing

Testing endpoints should aim for a 2xx response, not 300

There are a few special cases of endpoint tests:

heat
heat-cfn
glance

Requesting a GET purely on those standard endpoint URLs will return a 300 as a result.
(example: https://developer.openstack.org/api-ref/image/versions/index.html#id1)

3XX does not guarantee a successful request (could also only mean a redirection). We could consider getting the tenant_id of the current project and make a more "direct" api call on those endpoints.

Inspect Hypervisors

We should add the following checks:

check which hypervisors are active
RAM per Hypervisor (load)
CPUs per Hypervisor (load)
Available disk per Hypervisor

Service Endpoints should be retrieved by KeyStone

Currently all endpoints must be configured in the config.yml. Much more comfortable and also more flexible is it to ask Keystone for an available endpoint list.

$ openstack endpoint list --interface public -c 'Service Name' -c 'URL'

Tempest Introduction

short presentation for Peter
test tempest according to the complex task https://docs.google.com/document/d/1c5nJczosBY-_QWhaHs8BtJtyTVi7Q3me2oxWh_1xhbo/edit?usp=sharing

Add more (specific) tests

Ordered by importance:

Object storage (Swift/S3) : Upload / Download/ Delete data from Object Storage using the swift/s3 API
Volume (Nova/Cinder): Create a volume and attach it to an instance. Write/Read/Delete data. Clean-Up everything
Images (Glance): Upload/Delete an image (should be a small image, e.g. cirros)
Boot from a volume (Nova) : boot instance also from a volume (instead using a local disc)
Snapshots (Nova/Cinder): Start a new instance, create a snapshot, stop the instance, boot another instance from previous generated snapshot and
Orchestration (Heat): Upload a simple stack/ heat template (e.g. boot a new instance), run and stop it afterwards.
