+# Windsurf Test Discovery Setup
+
+## Issue
+Unittest discovery errors when using Windsurf's test runner with the `tests/` folder.
+
+## Solution
+1. **Updated pyproject.toml** - Added `tests` to the testpaths configuration
+2. **Created minimal conftest.py** - Removed complex imports that were causing discovery failures
+3. **Test discovery now works** for files matching `test_*.py` pattern
+
+## Current Status
+- ✅ Test discovery works for simple tests (e.g., `tests/test_discovery.py`)
+- ✅ All `test_*.py` files are discovered by pytest
+- ⚠️ Tests with complex imports may fail during execution due to module path issues
+
+## Running Tests
+
+### For test discovery only (Windsurf integration):
+```bash
+cd /home/oib/windsurf/aitbc
+python -m pytest --collect-only tests/
+```
+
+### For running all tests (with full setup):
+```bash
+cd /home/oib/windsurf/aitbc
+python run_tests.py tests/
+```
+
+## Test Files Found
+- `tests/e2e/test_wallet_daemon.py`
+- `tests/integration/test_blockchain_node.py`
+- `tests/security/test_confidential_transactions.py`
+- `tests/unit/test_coordinator_api.py`
+- `tests/test_discovery.py` (simple test file)
+
+## Notes
+- The original `conftest_full.py` contains complex fixtures requiring full module setup
+- To run tests with full functionality, restore `conftest_full.py` and use the wrapper script
+- For Windsurf's test discovery, the minimal `conftest.py` provides better experience
