Problem

Currently, the chart and documentation may become out of sync, and there's no automated validation to ensure:
- Documentation accurately reflects chart configuration
- No 'latest' tags are introduced in future changes
- Custom image workflows function correctly
- Chart automation works as expected

Solution

Enhance the existing pytest testing framework to include comprehensive validation of chart consistency, documentation accuracy, and automation workflows.

Acceptance Criteria

• [ ] Create tests to validate documentation against chart configuration
• [ ] Add tests to ensure no 'latest' tags are present in templates/values
• [ ] Implement integration tests for custom image workflow validation
• [ ] Add tests for chart update automation workflow
• [ ] Create smoke tests for deployed applications with new images
• [ ] Implement tests for GitHub Pages helm repository functionality
• [ ] Add validation tests for oc-mirror compatibility
• [ ] Document testing procedures and coverage
• [ ] Integrate new tests into CI/CD pipeline
• [ ] Create test reports and coverage metrics

Test Categories

1. Documentation Sync Tests
   • Validate values.yaml documentation matches actual values
   • Check README instructions against chart capabilities
   • Verify example configurations work as documented
2. Image Versioning Tests
   • Scan for any 'latest' tags in chart files
   • Validate all images use semantic versioning
   • Check image availability in configured registries
3. Automation Integration Tests
   • Test GitHub workflow triggers and outputs
   • Validate chart update automation
   • Verify helm repository functionality
4. Disconnected Environment Tests
   • Test oc-mirror compatibility
   • Validate chart templates without cluster connectivity
   • Verify no 'lookup' commands remain

Definition of Done

• Comprehensive test coverage for all epic objectives
• Tests integrated into CI/CD pipeline
• Documentation and chart remain synchronized
• Regression prevention for lookup commands and latest tags
• Automation workflows are validated and reliable
