Add comprehensive test suite and CI/CD pipeline

[erinlkolp]

Summary

This PR adds a comprehensive test suite for the vudials_client library along with a CI/CD pipeline to ensure code quality and test coverage across multiple Python versions.

Key Changes

Test Suite (tests/test_vudialsclient.py)

• Added 778 lines of comprehensive unit tests covering all public methods of VUUtil, VUAdminUtil, VUDial, and VUAdmin classes
• Tests cover:
  • URI construction with various parameter combinations
  • HTTP request handling (GET/POST, success/error cases)
  • All VUDial methods: list_dials(), get_dial_info(), set_dial_value(), set_dial_color(), set_dial_background(), get_dial_image_crc(), set_dial_name(), reload_hw_info(), easing configuration methods
  • All VUAdmin methods: provision_dials(), list_api_keys(), remove_api_key(), create_api_key(), update_api_key()
  • URL encoding, parameter validation, and error propagation
• Uses responses library for mocking HTTP requests
• Includes fixtures for common test objects in conftest.py

CI/CD Pipeline (.github/workflows/ci.yml)

• Automated testing on push to main and claude/** branches, and on pull requests
• Tests run against Python 3.11, 3.12, and 3.13
• Generates coverage reports with pytest-cov
• Uploads coverage artifacts for Python 3.12

Project Configuration (pyproject.toml)

• Added dev optional dependencies: pytest>=8.0, responses>=0.25, pytest-cov>=5.0
• Added pytest configuration with test path and coverage settings
• Configured coverage to track src/vudials_client source code

Notable Implementation Details

• Tests use mocked HTTP responses to avoid external dependencies
• Comprehensive parameter validation testing (URL encoding, special characters, boundary values)
• Error handling verification for HTTP status codes (404, 500, 403, 400, 401)
• File upload testing with mocked file operations
• Both positive and negative test cases for all methods
