+# Test Configuration Refactoring - COMPLETED
+
+## ✅ REFACTORING COMPLETE
+
+**Date**: March 3, 2026  
+**Status**: ✅ FULLY COMPLETED  
+**Scope**: Eliminated shell script smell by moving test configuration to pyproject.toml
+
+## Problem Solved
+
+### ❌ **Before (Code Smell)**
+- **Shell Script Dependency**: `run_all_tests.sh` alongside `pytest.ini`
+- **Configuration Duplication**: Test settings split between files
+- **CI Integration Issues**: CI workflows calling shell script instead of pytest directly
+- **Maintenance Overhead**: Two separate files to maintain
+- **Non-Standard**: Not following Python testing best practices
+
+### ✅ **After (Clean Integration)**
+- **Single Source of Truth**: All test configuration in `pyproject.toml`
+- **Direct pytest Integration**: CI workflows call pytest directly
+- **Standard Practice**: Follows Python testing best practices
+- **Better Maintainability**: One file to maintain
+- **Enhanced CI**: Comprehensive test workflows with proper categorization
+
+## Changes Made
+
+### ✅ **1. Consolidated pytest Configuration**
+
+**Moved from `pytest.ini` to `pyproject.toml`:**
+```toml
+[tool.pytest.ini_options]
+# Test discovery
+python_files = ["test_*.py", "*_test.py"]
+python_classes = ["Test*"]
+python_functions = ["test_*"]
+
+# Cache directory - prevent root level cache
+cache_dir = "dev/cache/.pytest_cache"
+
+# Test paths to run - include all test directories across the project
+testpaths = [
+    "tests",
+    "apps/blockchain-node/tests",
+    "apps/coordinator-api/tests",
+    "apps/explorer-web/tests",
+    "apps/pool-hub/tests",
+    "apps/wallet-daemon/tests",
+    "apps/zk-circuits/test",
+    "cli/tests",
+    "contracts/test",
+    "packages/py/aitbc-crypto/tests",
+    "packages/py/aitbc-sdk/tests",
+    "packages/solidity/aitbc-token/test",
+    "scripts/test"
+]
+
+# Python path for imports
+pythonpath = [
+    ".",
+    "packages/py/aitbc-crypto/src",
+    "packages/py/aitbc-crypto/tests",
+    "packages/py/aitbc-sdk/src",
+    "packages/py/aitbc-sdk/tests",

+    "apps/blockchain-node/tests",
+    "apps/pool-hub/src",
+    "apps/pool-hub/tests",
+    "apps/explorer-web/src",
+    "apps/explorer-web/tests",
+    "cli",
+    "cli/tests"
+]
+
+# Additional options for local testing
+addopts = [
+    "--verbose",
+    "--tb=short",
+    "--strict-markers",
+    "--disable-warnings",
+    "-ra"
+]
+
+# Custom markers
+markers = [
+    "unit: Unit tests (fast, isolated)",
+    "integration: Integration tests (may require external services)",
+    "slow: Slow running tests",
+    "cli: CLI command tests",
+    "api: API endpoint tests",
+    "blockchain: Blockchain-related tests",
+    "crypto: Cryptography tests",
+    "contracts: Smart contract tests",
+    "e2e: End-to-end tests (full system)",
+    "performance: Performance tests (measure speed/memory)",
+    "security: Security tests (vulnerability scanning)",
+    "gpu: Tests requiring GPU resources",
+    "confidential: Tests for confidential transactions",
+    "multitenant: Multi-tenancy specific tests"
+]
+
+# Environment variables for tests
+env = [
+    "AUDIT_LOG_DIR=/tmp/aitbc-audit",
+    "DATABASE_URL=sqlite:///./test_coordinator.db",
+    "TEST_MODE=true",
+    "SQLITE_DATABASE=sqlite:///./test_coordinator.db"
+]
+
+# Warnings
+filterwarnings = [
+    "ignore::UserWarning",
+    "ignore::DeprecationWarning",
+    "ignore::PendingDeprecationWarning",
+    "ignore::pytest.PytestUnknownMarkWarning",
+    "ignore::pydantic.PydanticDeprecatedSince20",
+    "ignore::sqlalchemy.exc.SADeprecationWarning"
+]
+
+# Asyncio configuration
+asyncio_default_fixture_loop_scope = "function"
+
+# Import mode
+import_mode = "append"
+```
+
+### ✅ **2. Updated CI Workflows**
+
+**Updated `.github/workflows/ci.yml`:**
+```yaml
+- name: Test (pytest)
+  run: poetry run pytest --cov=aitbc_cli --cov-report=term-missing --cov-report=xml
+
+- name: Upload coverage to Codecov
+  uses: codecov/codecov-action@v4
+  with:
+    file: ./coverage.xml
+    flags: unittests
+    name: codecov-umbrella
+```
+
+**Updated `.github/workflows/cli-tests.yml`:**
+```yaml
+- name: Run CLI tests
+  run: |
+    python -m pytest tests/cli/ -v --tb=short --disable-warnings --cov=aitbc_cli --cov-report=term-missing --cov-report=xml
+```
+
+### ✅ **3. Created Comprehensive Test Workflow**
+
+**New `.github/workflows/comprehensive-tests.yml`:**
+- **Unit Tests**: Fast, isolated tests across Python versions
+- **Integration Tests**: Tests requiring external services

+- `pytest.ini` → `pytest.ini.backup`
+
+## Benefits Achieved
+
+### ✅ **Eliminated Code Smell**
+- **Single Source of Truth**: All test configuration in `pyproject.toml`
+- **No Shell Script Dependency**: Direct pytest integration
+- **Standard Practice**: Follows Python testing best practices

+- **Better Coverage**: Comprehensive test categorization
+- **Parallel Execution**: Tests run in parallel by category
+- **Proper Reporting**: Enhanced test reporting and summaries
+
+### ✅ **Improved Developer Experience**
+- **Simplified Usage**: `pytest` command works everywhere
+- **Better Discovery**: Automatic test discovery across all directories
+- **Consistent Configuration**: Same configuration locally and in CI
+- **Enhanced Markers**: Better test categorization
+

+# Run tests via shell script
+./tests/run_all_tests.sh
+
+# Or manually with pytest.ini
+pytest --config=pytest.ini
+```
+
+**After:**
+```bash
+# Run tests directly
