Automation test files¶

Main files and modules:

• system_tests.sh - The file where tests start execution. This file processes the parameters specified from the command line and invokes run_tests.py.
• run_tests.py - Used to import your test files inside this file to run your test.
• settings.py - Contains environment variables used for environment customization. With this file, you can set such variables as path to ISO, nodes quantity, etc.
• environment.py - Contains methods for environment deploying, virtual machines creation and networking, installation of Fuel on the Fuel Master node, etc.
• nailgun_client.py - Contains functionality for nailgun handlers, methods and API that are supported by the nailgun client. The nailgun client uses the HTTP client that located in the helpers folder. The nailgun client is used in the Fuel web client.
