// Note: These tests are placeholders. The parseTerraformOutputs function
// calls executeBuildWithProgress which executes actual terraform commands.
// Proper testing requires either:
// 1. Mocking executeBuildWithProgress (refactor needed)
// 2. Integration tests with real terraform (slow)
// 3. Dependency injection of the executor (architectural change)
//
// We'll rely on:
// - Manual testing with real modules
// - Integration tests in test-integration/
// - Unit tests of property-extractor (already passing)
