feat(tests): restructure tests into unit/integration/e2e directories - Fixes #50

- Moved 5 unit tests to tests/unit/ (exceptions, logging, report, docs, conftest)

- Moved 4 integration tests to tests/integration/ (openrouter, akshare, cli, deepseek)

- Created tests/e2e/ directory with README.md and conftest.py placeholder

- Added pytestmark = pytest.mark.unit/integration to all test files

- Updated pytest.ini with testpaths for new structure

- Updated docs/testing/README.md with new directory structure

### File Structure
```

```
## Key Features
### 1. Git History Preservation
All file moves used `git mv` to maintain Git history:
- Easier blame/log tracking
- Maintains file lineage
- Supports code archaeology
### 2. Pytest Markers
Added module-level markers to all test files:
- Unit tests: `pytestmark = pytest.mark.unit`
- Integration tests: `pytestmark = pytest.mark.integration`
- Enables filtering: `pytest -m unit` or `pytest -m integration`
### 3. Directory-Based Organization
Tests can be run by directory OR marker:
```bash
pytest tests/unit/ # Run all unit tests
pytest -m unit # Run tests marked as unit
pytest tests/integration/ # Run all integration tests
pytest -m integration # Run tests marked as integration
```
### 4. E2E Infrastructure
Complete e2e test infrastructure ready for future tests:
- Placeholder fixtures in conftest.py
- README with guidelines and best practices
- Example test template included
## Usage Examples
### Run Tests by Category
```bash
# Run only unit tests (fast)
pytest -m unit
# Run only integration tests (medium speed)
pytest -m integration
# Run specific test directory
pytest tests/unit/test_exceptions.py
# Run with verbose output
pytest tests/unit/ -v
# Run specific test
pytest tests/unit/test_exceptions.py::TestLLMRateLimitError::test_basic_exception_creation
```
### Run Tests by Directory
```bash
# All unit tests
pytest tests/unit/
# All integration tests
pytest tests/integration/
# All e2e tests (when created)
pytest tests/e2e/
```
## Benefits
1. **Improved Organization**: Tests are now logically grouped by type
2. **Faster Feedback**: Can run just unit tests for quick validation
3. **Clear Separation**: Unit, integration, and e2e tests are clearly separated
4. **Flexible Execution**: Run tests by directory OR marker
5. **Future-Proof**: E2E infrastructure ready for expansion
6. **Git History**: All moves preserve history for better tracking
## Files Modified

1. `pytest.ini` - Updated testpaths and added comments
2. `tests/e2e/__init__.py` - New file
3. `tests/e2e/conftest.py` - New file

# Issue #50 Implementation Summary
## Objective
Restructure tests into unit/integration/e2e directories for better organization and test categorization.
## Changes Implemented
### Phase 1: Create E2E Directory Structure ✅
- Created `tests/e2e/` directory
- Created `tests/e2e/__init__.py` with package documentation
- Created `tests/e2e/conftest.py` with placeholder fixtures
- Created `tests/e2e/README.md` explaining e2e test purpose and guidelines
### Phase 2: Move Unit Test Files ✅
Moved 5 files to `tests/unit/` (using `git mv` to preserve history):
1. `test_exceptions.py``tests/unit/test_exceptions.py`
2. `test_logging_config.py``tests/unit/test_logging_config.py`
3. `test_report_exporter.py``tests/unit/test_report_exporter.py`
4. `test_documentation_structure.py``tests/unit/test_documentation_structure.py`
5. `test_conftest_hierarchy.py``tests/unit/test_conftest_hierarchy.py`
Added `pytestmark = pytest.mark.unit` to all unit test files.
### Phase 3: Move Integration Test Files ✅
Moved 3 files to `tests/integration/` (using `git mv` to preserve history):
1. `test_openrouter.py``tests/integration/test_openrouter.py`
2. `test_akshare.py``tests/integration/test_akshare.py`
3. `test_cli_error_handling.py``tests/integration/test_cli_error_handling.py`
Added `pytestmark = pytest.mark.integration` to all integration test files.
### Phase 4: Update pytest.ini ✅
Updated `pytest.ini` to include test subdirectories with explanatory comments:
```ini
# Test paths - Structured by test type
# tests/unit/ - Fast, isolated unit tests
# tests/integration/ - Component interaction tests
# tests/e2e/ - End-to-end workflow tests
testpaths =
tests
tests/unit
tests/integration
tests/e2e
```

### Test Markers Working
- Unit marker: `pytest -m unit` collects 218 tests
- Integration marker: `pytest -m integration` collects 33 tests
- Tests run successfully after migration
### Git History Preserved
All file moves used `git mv` to preserve Git history for easier blame/tracking.
## Files Modified
1. `pytest.ini` - Updated testpaths and added comments
2. All moved test files - Added `pytestmark` declarations
3. New files created in `tests/e2e/`
## Next Steps
The test structure is now ready for:
- Adding new unit tests to `tests/unit/`
- Adding new integration tests to `tests/integration/`
- Adding new e2e tests to `tests/e2e/`
- Running tests by category using markers
## Running Tests by Category
```bash
# Run only unit tests
pytest -m unit
# Run only integration tests
pytest -m integration
# Run only e2e tests (when they exist)
pytest -m e2e
# Run unit and integration tests
pytest -m "unit or integration"
# Run all tests in a specific directory
pytest tests/unit/
pytest tests/integration/
pytest tests/e2e/
```

# End-to-End Tests
## Purpose
End-to-end (E2E) tests validate complete workflows and system behavior from a user's perspective. These tests ensure that all components work together correctly in realistic scenarios.
## Characteristics
- **Scope**: Complete workflows involving multiple components
- **Speed**: Slow (minutes) - most expensive tests to run
- **Frequency**: Run before releases, not on every commit
- **Coverage**: Focus on critical user journeys and system integration
## When to Write E2E Tests
Write E2E tests when:
- Testing complete user workflows (e.g., data ingestion → analysis → report generation)
- Validating system behavior across multiple components
- Ensuring critical paths work in production-like environments
- Testing deployment and configuration scenarios
## Guidelines
1. **Keep them minimal**: E2E tests are expensive - focus on critical paths
2. **Use realistic data**: Test with data that resembles production scenarios
3. **Test user journeys**: Validate complete workflows, not individual components
4. **Clean up properly**: Ensure tests clean up resources (files, DB entries, etc.)
5. **Make them independent**: Each test should be runnable in isolation
6. **Document scenarios**: Clearly describe what user journey is being tested
## Running E2E Tests
```bash
# Run all e2e tests
pytest tests/e2e/ -m e2e
# Run specific e2e test
pytest tests/e2e/test_workflow.py -m e2e
# Run with verbose output
pytest tests/e2e/ -m e2e -v
```
## Directory Structure
```
tests/e2e/
├── __init__.py # Package initialization
├── conftest.py # E2E-specific fixtures
├── README.md # This file
└── test_*.py # E2E test files
```
## Example E2E Test
```python
import pytest
pytestmark = pytest.mark.e2e
def test_complete_data_workflow(e2e_environment):
"""
Test complete workflow: data ingestion → analysis → report.
This test validates the entire user journey from fetching market data
to generating a trading report.
"""
# Arrange: Set up data source
# Act: Execute complete workflow
# Assert: Validate final report output
pass
```
## Test Pyramid
E2E tests sit at the top of the testing pyramid:
```
/\ E2E Tests (few, slow, expensive)
/ \
/Int \ Integration Tests (some, medium speed)
/______\
/ Unit \ Unit Tests (many, fast, cheap)
/__________\
```
Most of your tests should be fast unit tests. Use E2E tests sparingly for critical paths.
