TranscriptBuilder - Generate Test Data + +```python +from tests.helpers.transcript_parser import TranscriptBuilder + +builder = TranscriptBuilder(Path("test.jsonl")) +builder.add_user_message("Hello") +builder.add_assistant_message("Hi there!") +builder, tool_id = builder.add_tool_use("Read", {"file_path": "/test.txt"}) +builder.add_tool_result(tool_id, "File content") +builder.build() +``` + +### 3. LangSmith Client - Verify Traces + +```python +from tests.helpers.langsmith_client import LangSmithTestClient + +client = LangSmithTestClient() + +# Fetch traces +traces = client.fetch_traces(limit=10) + +# Get child runs +children = client.get_child_runs(parent_run_id) +``` + +## Running Tests + +### Unit Tests Only (Default) + +```bash +# Run all unit tests +.venv/bin/pytest tests/unit/ -v + +# Run specific test file +.venv/bin/pytest tests/unit/test_message_parsing.py -v + +# Run specific test +.venv/bin/pytest tests/unit/test_message_parsing.py::TestGetContent::test_get_content_from_message_wrapper -v +``` + +### With Coverage + +```bash +# Generate coverage report +.venv/bin/pytest tests/unit/ --cov=tests --cov-report=html --cov-report=term-missing + +# View HTML report +open htmlcov/index.html +``` + +### Integration Tests (Future) + +Integration tests require `CC_LANGSMITH_API_KEY`: + +```bash +# Run integration tests +CC_LANGSMITH_API_KEY="your_key" .venv/bin/pytest tests/integration/ -v -m integration +``` + +## Test Fixtures + +### Sample Data Fixtures (conftest.py) + +- `sample_user_message` - Example user message +- `sample_assistant_message` - Assistant message with tool use +- `sample_tool_result` - Tool result message +- `sample_streaming_parts` - SSE streaming parts + +### Helper Fixtures + +- `bash_executor` - BashRunner instance +- `langsmith_client` - LangSmith API client +- `state_manager` - State file manager +- `transcript_builder` - Transcript generator +- `temp_state_file` - Isolated state file +- `temp_transcript` - Temporary transcript path + +### Example Usage + +```python +def test_example(bash_executor, sample_assistant_message): + msg = json.dumps(sample_assistant_message) + result = bash_executor.call_function("get_content", msg) + content = json.loads(result) + assert len(content) == 3 +``` + +## Troubleshooting + +### Tests Failing with "Function not found" + +The bash_runner removes the early exit check from stop_hook.sh. If functions are not found, ensure: +1. stop_hook.sh is in the correct location +2. The sed pattern matches the early exit block + +### State Management Tests Using Real State File + +The `STATE_FILE` environment variable should point to a temp file, but stop_hook.sh has it hardcoded. To fix: +- Modify stop_hook.sh line 47 to: `STATE_FILE="${STATE_FILE:-$HOME/.claude/state/langsmith_state.json}"` +- Or: Run tests in isolation and clean up afterwards + +### Integration Tests Require API Key + +Integration tests need a valid LangSmith API key: + +```bash +export CC_LANGSMITH_API_KEY="lsv2_pt_..." +.venv/bin/pytest tests/integration/ -v -m integration +``` + +## Contributing + +When adding new functions to stop_hook.sh: + +1. Add corresponding unit tests +2. Use BashRunner to test in isolation +3. Add sample fixtures if needed +4. Ensure 80%+ test coverage +5. Run tests before committing + +Example: + +```python +def test_new_function(bash_executor): + """Test description""" + result = bash_executor.call_function("new_function", "arg1", "arg2") + assert
