feat: Add comprehensive multi-layered testing framework
Implement extensive testing infrastructure for Githut2Gerrit GitHub Actions best practices: * Add .github/workflows/testing.yaml with 5-tier testing strategy: - shell-tests: Unit tests for bash script functions (3min timeout) - matrix-tests: Cross-platform testing (Ubuntu LTS versions) - integration-tests: End-to-end workflow validation (8min timeout) - dry-run-integration: Real Gerrit connectivity testing (10min timeout) - security-validation: Input sanitization and credential checks (3min timeout) * Create tests/test-functions.sh for URL parsing validation: - extract_hostname(), extract_change_number() and extract_project() tests - Edge case handling (empty/malformed URLs) - JSON parsing validation with jq * Add test fixtures and mock data: - tests/fixtures/sample-gerrit-response.json - tests/fixtures/sample-gitreview - Realistic test data without external dependencies * Implement security testing: - Command injection prevention - Secret exposure detection - Input sanitization validation * Add comprehensive testing documentation (TESTING.md): - Testing architecture overview - Coverage matrix for both composite action and reusable workflow - Local and CI execution instructions Testing covers both action.yaml (composite) and github2gerrit.yaml (reusable workflow) with continue-on-error patterns for expected failures and timeout protection. The change resolves testing gaps identified in repository analysis. Signed-off-by: Anil Belur <abelur@linuxfoundation.org>
