stx-test

StarlingX Test repository for automated test cases.

This repository contains the test framework and test cases for verifying StarlingX. The test framework provides tools for configuration, automation, and execution of tests, with the ability to run against diverse StarlingX lab environments.

Pre-Requisites

To use this repository, ensure the following requirements are met:

1. Operating System:

   • Ubuntu 22.04 or later.

2. Network Requirements:

   • The RunAgent (test execution machine) must:
     • Have internet access for pulling images and dependencies.
     • Be able to connect to your StarlingX system(s) via SSH.

3. Required Tools: Install the following tools:

   # Python 3.11
   sudo apt update
   sudo apt install -y python3.11 python3-pip
   
   # pipenv
   pip install --user pipenv

Setup and Installation

1. Clone the Repository:

   git clone https://opendev.org/starlingx/test.git
   cd test

2. Setup Gerrit for Code Review: The procedure to set up Gerrit for StarlingX is the same as for other projects hosted on OpenDev, such as OpenStack. Refer to the OpenStack Contributor Guide for detailed instructions.

   • Key Setup and Repository Configuration:

     # Generate an SSH key (recommended: ED25519; RSA is also supported)
     ssh-keygen -t ed25519 -C "<your email address>"
     ssh-add ~/.ssh/id_ed25519
     
     # Alternatively, generate an RSA key for compatibility with older systems:
     ssh-keygen -t rsa -b 4096 -C "<your email address>"
     ssh-add ~/.ssh/id_rsa

     • Add your SSH key to Gerrit:
       • Navigate to https://review.opendev.org/settings/#SSHKeys.
       • Copy the contents of your public key file (~/.ssh/id_ed25519.pub or ~/.ssh/id_rsa.pub).
       • Paste the key into the SSH key field on the Gerrit settings page.

   • Sign the Individual Contributor License Agreement (ICLA): Projects hosted on OpenDev, including StarlingX, require signing the OpenStack Individual Contributor License Agreement (ICLA). This step is outlined in the OpenStack Contributor Guide and the OpenDev Developer Documentation. Follow these instructions to complete the process before submitting changes.

   • Fetch Gerrit Hooks: Fetch Gerrit hooks immediately after cloning to enable automatic Change-Id generation during commits and verify your SSH key setup:

     git review -s

     Example output:

     Creating a git remote called 'gerrit' that maps to:
             ssh://<open-review-email-or-username>@review.opendev.org:29418/starlingx/test.git

     If there is an issue with your SSH configuration (e.g., missing or incorrect SSH key), you will see an error message indicating the problem, such as "Permission denied (publickey)".

     • (Optional) If you cloned the repository using HTTPS or need Gerrit hooks:

       • Add a Gerrit remote (only needed if the default remote does not point to Gerrit).

         git remote add gerrit ssh://<your-gerrit-username>@review.opendev.org/starlingx/test.git

3. Install Python Dependencies:

   # Create and activate a virtual environment
   pipenv shell
   
   # Sync project dependencies
   pipenv sync

4. Install Pre-Commit Hooks:

   # Install pre-commit hooks for linting and formatting (run in the repository's root directory)
   pre-commit install

Configuration

The framework relies on configuration files found under the config directory. These include settings for labs, Docker, Kubernetes, and logging. Default files are provided, but you can customize configurations using CLI options.

Steps to Configure

1. Lab Configuration (`config/lab/files/default.json5`):
   • Holds lab details such as floating IPs, type, and capabilities.
   • For custom setups:
     • Use a template file (e.g., template_simplex.json5) as a base.
     • Update use_jump_host and jump_server_config if a jump server is used.
2. Docker Configuration (`config/docker/files/default.json5`):
   • Specify credentials for Docker registries used during testing.
3. Lab Capability Scanner:

   • Automatically detect and update lab capabilities:

     python scripts/lab_capability_scanner.py --lab_config_file=<lab_config_file>

You are now ready to execute tests!

Running Tests

1. Basic Example: Run a specific test case:

   python framework/runner/scripts/test_executor.py --tests_location=<testcase_location>

2. Custom Configurations: Use non-default configurations:

   python framework/runner/scripts/test_executor.py \
     --tests_location=<testcase_location> \
     --lab_config_file=<config_location>

   Example:

   python framework/runner/scripts/test_executor.py \
     --tests_location=testcases/cloud_platform/sanity \
     --lab_config_file=config/lab/files/custom_config.json5

3. UI Testing (Optional): Install Chrome for running WebDriver-based UI tests:

   wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
   sudo dpkg -i google-chrome-stable_current_amd64.deb
   sudo apt -f install
   google-chrome --version

Contribution

2. Coding Standards:
   • Ensure your code adheres to project conventions. While more detailed best practices are being refined and will be provided in future updates, the following standards are currently enforced:
     • Use Google style, PEP-compliant docstrings for every function and module. These docstrings should align with the principles outlined in PEP 257 (Docstring Conventions). Tools for auto-generating these docstrings are available in IDEs such as VSCode and PyCharm.
     • Include type hints for all function arguments and return types.
     • Use f-strings for string formatting.
   • Pre-commit hooks will run automatically on every commit once installed to ensure formatting and linting.
   • Tools Enforced by Pre-Commit Hooks:
     • pre-commit
     • black
     • isort
     • flake8
3. Submitting Changes:

   • Ensure your commit messages adhere to the guidelines in the OpenStack Git Commit Message Guidelines.

   • Submit changes for Gerrit review using the following example:

     git commit -s # include sign-off
     git review
