# Integration Tests CI Workflow
#
# This workflow runs on every push and pull request to main branch.
# It includes:
# - Unit tests (fast, every PR)
# - Integration tests with mocks (fast, every PR)
# - Integration tests with Kind cluster (thorough, every PR)
#
# Test hierarchy:
# 1. Unit tests - fastest, no infrastructure
# 2. Mock integration tests - fast, mocked external services
# 3. Kind cluster tests - slower, real kubectl operations
