## Issues Identified and Fixed

### 1. Import Path Problems ✅ FIXED
- **Issue**: Tests had incorrect import paths for vultr_dns_mcp modules
- **Fix**: Updated all import statements to use correct package structure
- **Files affected**: conftest.py, test_mcp_server.py

### 2. Async/Await Pattern Issues ✅ FIXED  
- **Issue**: Incorrect usage of async patterns with FastMCP Client
- **Fix**: Fixed async context manager usage and proper await patterns
- **Files affected**: test_mcp_server.py, all async test methods

### 3. Mock Configuration Problems ✅ FIXED
- **Issue**: Mock setup didn't match actual API response structure
- **Fix**: Updated mock configurations to match current Vultr API
- **Files affected**: conftest.py fixtures

### 4. Test Data Structure Mismatches ✅ FIXED
- **Issue**: Sample data didn't match current API response format
- **Fix**: Updated test fixtures with correct data structures
- **Files affected**: conftest.py sample_* fixtures

### 5. Missing Error Handling Tests ✅ FIXED
- **Issue**: Insufficient error scenario testing
- **Fix**: Added comprehensive error handling test cases
- **Files affected**: test_mcp_server.py TestMCPToolErrors class

## Files Created/Updated

### Core Fixes
- `conftest_fixed.py` - Updated test configuration with proper mocks
- `test_mcp_server_fixed.py` - Fixed MCP server tests
- `pyproject_fixed.toml` - Updated dependencies and configuration
- `run_tests_fixed.py` - Improved test runner script

### Key Improvements
1. **Better Mock Setup**: Comprehensive mock responses matching Vultr API
2. **Proper Async Patterns**: Correct FastMCP Client usage throughout
3. **Error Handling**: Robust error scenario testing
4. **Dependency Management**: Updated pyproject.toml with correct versions
5. **Test Organization**: Clear test categorization with pytest markers

## How to Apply the Fixes

### Quick Fix (Recommended)
```bash
# In your vultr-dns-mcp repository directory:
cp conftest_fixed.py tests/conftest.py
cp test_mcp_server_fixed.py tests/test_mcp_server.py
cp pyproject_fixed.toml pyproject.toml
cp run_tests_fixed.py run_tests.py
```

### Manual Application
1. Replace `tests/conftest.py` with `conftest_fixed.py`
2. Replace `tests/test_mcp_server.py` with `test_mcp_server_fixed.py`
3. Update `pyproject.toml` with fixed dependencies
4. Replace `run_tests.py` with improved version

### Install Dependencies
```bash
pip install -e .[dev]
# Or manually:
pip install pytest pytest-asyncio pytest-cov fastmcp httpx pydantic click
```

### Run Tests
```bash
# Run all tests
pytest tests/ -v

# Run only MCP tests  
pytest tests/ -m mcp -v

# Run with coverage
pytest tests/ --cov=vultr_dns_mcp --cov-report=html

# Using the improved test runner
python run_tests.py --type mcp --verbose --coverage
```

## Expected Results After Fixes

✅ All basic MCP server tests should pass
✅ Tool invocation tests should work correctly  
✅ Resource discovery tests should succeed
✅ Error handling tests should validate properly
✅ Integration workflow tests should complete
✅ Validation logic tests should work as expected

## Common Issues and Solutions

### If tests still fail:

1. **Import Errors**: Ensure you're running tests from the repository root
2. **Async Errors**: Verify pytest-asyncio is installed and configured
3. **Mock Errors**: Check that all mock methods are properly configured
4. **FastMCP Errors**: Ensure compatible FastMCP version is installed

### Debugging Tips:
```bash
# Run single test with maximum verbosity
pytest tests/test_mcp_server.py::TestMCPTools::test_list_dns_domains_tool -vvv

# Check installed packages
pip list | grep -E "(pytest|fastmcp|httpx)"

# Validate test discovery
pytest --collect-only tests/
```

## Next Steps

1. Apply the fixes to your repository
2. Run the test suite to verify all tests pass
3. Consider adding additional test cases for edge scenarios
4. Update CI/CD configuration if needed
5. Document any additional setup requirements

The fixed test suite provides comprehensive coverage of the MCP functionality
while following FastMCP best practices and proper async patterns.
