For negative tests that are asserting an argparse failure it would be useful to assert the specific reason for the failure in the test rather than just getting an exception, especially to avoid false positives in the tests when what is being tested and failing isn't the actual expected reason for the failure. This wraps the check_parser code that parses the args and mocks sys.stderr so we can trap that output and put it in the exception message that gets raised to the test. As a result, we can tighten up a test that was passing before for the wrong reason [1].

OpenStackClient
OpenStackClient (aka OSC) is a command-line client for OpenStack that brings the command set for Compute, Identity, Image, Network, Object Store and Block Storage APIs together in a single shell with a uniform command structure.
The primary goal is to provide a unified shell command structure and a common language to describe operations in OpenStack.

Getting Started
OpenStack Client can be installed from PyPI using pip:
pip install python-openstackclient
There are a few variants on getting help. A list of global options
and supported commands is shown with --help
:
openstack --help
There is also a help
command that can be used to get
help text for a specific command:
openstack help
openstack help server create
If you want to make changes to the OpenStackClient for testing and contribution, make any changes and then run:
python setup.py develop
or:
pip install -e .
Configuration
The CLI is configured via environment variables and command-line options as listed in https://docs.openstack.org/python-openstackclient/latest/cli/authentication.html.
Authentication using username/password is most commonly used:
export OS_AUTH_URL=<url-to-openstack-identity>
export OS_IDENTITY_API_VERSION=3
export OS_PROJECT_NAME=<project-name>
export OS_PROJECT_DOMAIN_NAME=<project-domain-name>
export OS_USERNAME=<username>
export OS_USER_DOMAIN_NAME=<user-domain-name>
export OS_PASSWORD=<password> # (optional)
The corresponding command-line options look very similar:
--os-auth-url <url>
--os-identity-api-version 3
--os-project-name <project-name>
--os-project-domain-name <project-domain-name>
--os-username <username>
--os-user-domain-name <user-domain-name>
[--os-password <password>]
If a password is not provided above (in plaintext), you will be interactively prompted to provide one securely.
