Implement 100% Test Coverage

# Implement 100% Test Coverage

## 🎯 Objective
Achieve 100% test coverage for the pytryfi library to ensure reliability, catch regressions early, and maintain code quality. This includes unit tests for all modules, integration tests for API interactions, and edge case testing.

## 📋 Background
Currently, pytryfi lacks comprehensive test coverage. Adding thorough tests will:
- Prevent regressions when adding new features
- Enable confident refactoring
- Serve as documentation for expected behavior
- Improve overall code quality

## 🔧 Implementation Plan

### 1. Set Up Testing Infrastructure

#### Create `pytest.ini`
```ini
[tool:pytest]
testpaths = tests
python_files = test_*.py
python_classes = Test*
python_functions = test_*
addopts = 
    --cov=pytryfi
    --cov-report=html
    --cov-report=term-missing
    --cov-fail-under=100
    -v
```

#### Create `.coveragerc`
```ini
[run]
source = pytryfi
omit = 
    */tests/*
    */__pycache__/*
    */test_*

[report]
exclude_lines =
    pragma: no cover
    def __repr__
    raise AssertionError
    raise NotImplementedError
    if __name__ == .__main__.:
    if TYPE_CHECKING:
```

#### Update `requirements-test.txt`
```
pytest>=7.4.0
pytest-cov>=4.1.0
pytest-asyncio>=0.21.0
pytest-mock>=3.11.0
responses>=0.23.0
freezegun>=1.2.0
```

### 2. Create Test Structure

### 8. Coverage Report Script

#### `scripts/coverage.sh`
```bash
#!/bin/bash
# Run tests with coverage report

echo "Running tests with coverage..."
pytest --cov=pytryfi --cov-report=html --cov-report=term-missing

echo "Opening coverage report..."
open htmlcov/index.html

# Check if we meet coverage threshold
coverage report --fail-under=100
if [ $? -eq 0 ]; then
    echo "✅ Coverage goal met!"
else
    echo "❌ Coverage below 100%"
    exit 1
fi
```

## 📝 Benefits

1. **Reliability**: Catch bugs before they reach production
2. **Confidence**: Refactor without fear of breaking things
3. **Documentation**: Tests serve as usage examples
4. **Quality**: Maintain high code standards
5. **CI/CD**: Enable automated testing in pipelines

## 🧪 Testing Strategy

1. **Unit Tests**: Test each class/method in isolation
2. **Integration Tests**: Test component interactions
3. **Error Tests**: Test all error paths
4. **Edge Cases**: Test boundary conditions
5. **Mocking**: Mock external dependencies (API calls)
