The requirements specify what the testing infrastructure should provide (directory structure, fixtures, CI/CD configuration, documentation), not functional behaviors of the byokg-rag system that can be tested with property-based tests. + +All acceptance criteria in the requirements document describe: +- File system structure to create (directories, files) +- Configuration to add (dependencies, CI/CD workflows) +- Documentation to write (README, test patterns) +- Test coverage targets to achieve (percentage goals) +- Test quality standards to follow (naming conventions, docstrings) + +None of these are testable properties of a system's behavior. They are deliverables and standards for the testing infrastructure itself. Therefore, there are no correctness properties to specify for this feature. + +The testing infrastructure will enable property-based testing of the byokg-rag system in the future, but the infrastructure creation itself is not subject to property-based testing. + +## Error Handling + +### Test Execution Errors + +The testing infrastructure handles several error scenarios: + +#### Missing Dependencies + +When required test dependencies are not installed: + +```python +try: + import pytest +except ImportError: + print("ERROR: pytest is not installed.
