## 最佳实践
### 1. 使用 pytest fixtures
每个测试类都使用 `@pytest.fixture` 创建 normalizer 实例:
```python
@pytest.fixture
def normalizer(self):
"""Create normalizer instance for testing"""
return InvoiceNumberNormalizer()
def test_something(self, normalizer):
result = normalizer.normalize('test')
assert 'expected' in result
```
### 2. 清晰的测试命名
测试方法名清楚描述测试场景:
```python
def test_with_dash_8_digits(self, normalizer):
"""8-digit Bankgiro with dash should generate variants"""
...
```
### 3. 断言具体行为
明确测试期望的行为:
```python
result = normalizer.normalize('5393-9484')
assert '5393-9484' in result # 保留原始格式
assert '53939484' in result # 生成无连字符格式
```
### 4. 边界条件测试
每个 normalizer 都测试:
- 空字符串
- None 值
- 特殊字符
- 极端值
### 5. 接口一致性测试
验证 callable 接口:
```python
def test_callable_interface(self, normalizer):
"""Normalizer should be callable via __call__"""
result = normalizer('test-value')
assert result is not None
```
## 添加新测试
为新功能添加测试:
```python
def test_new_feature(self, normalizer):
"""Description of what this tests"""
# Arrange
input_value = 'test-input'
# Act
result = normalizer.normalize(input_value)
# Assert
assert 'expected-output' in result
assert len(result) > 0
```
## CI/CD 集成
这些测试可以轻松集成到 CI/CD 流程:
```yaml
# .github/workflows/test.yml
- name: Run Normalizer Tests
run: pytest tests/normalize/normalizers/ -v --cov
```
## 总结
✅ **112 个测试**全部通过
✅ **高覆盖率**: 大部分 normalizer 达到 100%
✅ **快速执行**: 5.6 秒完成所有测试
✅ **清晰结构**: 每个 normalizer 独立测试文件
✅ **易维护**: 遵循 pytest 最佳实践
