Compatibility Test Matrix Skill

Overview

This skill implements comprehensive compatibility testing across runtime versions, operating systems, and dependency versions to ensure SDKs work reliably in all supported environments.

Capabilities

Test across runtime versions (Node.js, Python, Java, etc.)
Validate OS compatibility (Windows, macOS, Linux)
Check dependency compatibility matrices
Generate compatibility reports
Configure CI matrix builds
Test browser compatibility for web SDKs
Validate cloud platform compatibility
Support containerized test environments

Target Processes

Compatibility Testing
SDK Testing Strategy
Multi-Language SDK Strategy

Integration Points

GitHub Actions matrix builds
tox for Python version testing
nox for advanced Python testing
Docker for isolated environments
BrowserStack/Sauce Labs for browsers
Cross-platform CI systems

Input Requirements

Supported runtime versions
Target operating systems
Dependency version ranges
Browser support requirements
Cloud platform targets

Output Artifacts

CI matrix configuration
Compatibility test suite
Multi-version test environments
Compatibility matrix documentation
Test result aggregation
Support policy documentation

Usage Example

skill:
  name: compatibility-test-matrix
  context:
    language: python
    runtimes:
      - "3.8"
      - "3.9"
      - "3.10"
      - "3.11"
      - "3.12"
    operatingSystems:
      - ubuntu-latest
      - macos-latest
      - windows-latest
    dependencies:
      requests: [">=2.25", ">=2.28", ">=2.31"]
    browsers:
      - chrome
      - firefox
      - safari

Best Practices

Test minimum and maximum supported versions
Include pre-release runtime versions
Automate matrix expansion
Document support policy clearly
Track compatibility over time
Fail fast on compatibility breaks
