# Testing Issues Documentation

**Status**: Active Issues Documented  
**Reporter**: Claude Code Agent

This document captures the testing problems encountered and their solutions for future reference.

## Issue #1: SQLAlchemy Relationship Resolution Error

**Problem**: Test runner and direct pytest failing with SQLAlchemy errors:
```
NameError: Module 'models' has no mapped classes registered under the name 'batch_job'
sqlalchemy.exc.InvalidRequestError: When initializing mapper Mapper[User(users)], expression 'backend.models.batch_job.BatchJob' failed to locate a name
```

**Root Cause**: The `BatchJob` and `BatchJobItem` models existed in `backend/models/batch_job.py` but were not imported in the models `__init__.py` file. This caused SQLAlchemy to fail when resolving relationships defined in the User model.

**Solution**: Added missing imports to `backend/models/__init__.py`:
```python
# Before (missing imports)
from .user import User, RefreshToken, APIKey, EmailVerificationToken, PasswordResetToken
from .summary import Summary, ExportHistory

# After (fixed)
from .user import User, RefreshToken, APIKey, EmailVerificationToken, PasswordResetToken
from .summary import Summary, ExportHistory
from .batch_job import BatchJob, BatchJobItem  # Added this line

__all__ = [
    # ... existing models ...
    "BatchJob",      # Added
    "BatchJobItem",  # Added
]
```

**Verification**: Auth service tests went from 20/21 failing to 21/21 passing.

## Issue #2: Pydantic Configuration Validation Errors

**Problem**: Tests failing with Pydantic validation errors:
```
pydantic_core._pydantic_core.ValidationError: 19 validation errors for VideoDownloadConfig
anthropic_api_key: Extra inputs are not permitted [type=extra_forbidden]
openai_api_key: Extra inputs are not permitted [type=extra_forbidden]
...
```

**Root Cause**: The `VideoDownloadConfig` class extends `BaseSettings` and automatically loads environment variables. However, the environment contained many API keys and configuration variables that weren't defined in the model schema. Pydantic 2.x defaults to `extra="forbid"` which rejects unknown fields.

**Solution**: Modified the `VideoDownloadConfig` class configuration:
```python
# File: backend/config/video_download_config.py
class VideoDownloadConfig(BaseSettings):
    # ... model fields ...
    
    class Config:
        env_file = ".env"
        env_prefix = "VIDEO_DOWNLOAD_"
        case_sensitive = False
        extra = "ignore"  # Added this line to allow extra environment variables
```

**Verification**: Enhanced video service tests went from collection errors to 13/23 passing.

## Issue #3: Test Runner Result Parsing Bug

**Problem**: The custom test runner consistently reports "0/X passed" even when tests are actually passing.

**Evidence**:
- Test runner shows: `Completed unit tests: 0/229 passed`
- Direct pytest shows: `182 passed, 61 failed, 38 errors` (75% pass rate)
- Individual test files run successfully when tested directly

**Root Cause**: Bug in the test runner's pytest result parsing logic. The `TestExecutor` class in `backend/test_runner/core/test_execution.py` is not correctly parsing the pytest output or exit codes.

**Current Status**: **UNRESOLVED** - Test runner display bug exists but does not affect actual test functionality.

**Workaround**: Use direct pytest commands for accurate results:
```bash
# Instead of: ./run_tests.sh run-unit
# Use: PYTHONPATH=/path/to/project python3 -m pytest backend/tests/unit/

# For specific tests:
PYTHONPATH=/Users/enias/projects/my-ai-projects/apps/youtube-summarizer python3 -m pytest backend/tests/unit/test_auth_service.py -v
```

## Issue #4: Test Environment Setup

**Problem**: Tests may fail if run without proper PYTHONPATH configuration.

**Solution**: Always set PYTHONPATH when running tests directly:
```bash
export PYTHONPATH="/Users/enias/projects/my-ai-projects/apps/youtube-summarizer"
# or
PYTHONPATH=/Users/enias/projects/my-ai-projects/apps/youtube-summarizer python3 -m pytest
```

**Verification Script**: Use `./scripts/validate_test_setup.py` to check environment.

## Current Test Status (as of 2025-08-27 01:45 UTC)

### ✅ Working Test Categories:
- **Authentication Tests**: 21/21 passing (100%)
- **Core Service Tests**: Most passing
- **Database Model Tests**: Working after BatchJob fix
- **Basic Integration Tests**: Many passing

### ❌ Known Failing Areas:
- **Enhanced Video Service**: 10/23 failing (test implementation issues)
- **Video Downloader Tests**: Multiple failures (mocking issues)
- **AI Service Tests**: Some import/dependency errors
- **Complex Integration Tests**: Various issues

### Overall Stats:
- **Total Discovered**: 241 tests
- **Passing**: 182 tests (75%)
- **Failing**: 61 tests
- **Errors**: 38 tests

## Recommended Next Steps

1. **Fix Test Runner Parsing Bug**: 
   - Investigate `backend/test_runner/core/test_execution.py`
   - Fix pytest result parsing logic
   - Ensure proper exit code handling

2. **Address Remaining Test Failures**:
   - Fix mocking issues in video downloader tests
   - Resolve import/dependency errors in AI service tests
   - Update test implementations for enhanced video service

3. **Improve Test Environment**:
   - Create more reliable test fixtures
   - Improve test isolation
   - Add better error reporting

4. **Documentation**:
   - Update TESTING-INSTRUCTIONS.md with current status
   - Document workarounds for known issues
   - Create debugging guide for test failures

## Commands for Testing Tomorrow

```bash
# Quick verification (works reliably)
PYTHONPATH=/Users/enias/projects/my-ai-projects/apps/youtube-summarizer python3 -m pytest backend/tests/unit/test_auth_service.py -v

# Full unit test run (accurate results)
PYTHONPATH=/Users/enias/projects/my-ai-projects/apps/youtube-summarizer python3 -m pytest backend/tests/unit/ --tb=no -q

# Debug specific failures
PYTHONPATH=/Users/enias/projects/my-ai-projects/apps/youtube-summarizer python3 -m pytest backend/tests/unit/test_enhanced_video_service.py -v --tb=short

# Test runner (has display bug but still useful for discovery)
./run_tests.sh list --category unit
```
