## 🚀 运行测试
### 运行所有测试
```bash
# 在 WSL 环境中
conda activate invoice-py311
pytest tests/ -v
```
### 运行特定模块的测试
```bash
# Normalizer 测试
pytest tests/normalize/ -v
# 独立 normalizer 测试
pytest tests/normalize/normalizers/ -v
# PDF 测试
pytest tests/pdf/ -v
# Utils 测试
pytest tests/utils/ -v
# Inference 测试
pytest tests/inference/ -v
```
### 运行单个测试文件
```bash
pytest tests/normalize/normalizers/test_amount_normalizer.py -v
pytest tests/pdf/test_extractor.py -v
pytest tests/utils/test_utils.py -v
```
### 查看测试覆盖率
```bash
# 生成覆盖率报告
pytest tests/ --cov=src --cov-report=html
# 仅查看某个模块的覆盖率
pytest tests/normalize/ --cov=src/normalize --cov-report=term-missing
```
### 运行特定测试
```bash
# 按测试类运行
pytest tests/normalize/normalizers/test_amount_normalizer.py::TestAmountNormalizer -v
# 按测试方法运行
pytest tests/normalize/normalizers/test_amount_normalizer.py::TestAmountNormalizer::test_integer_amount -v
# 按关键字运行
pytest tests/ -k "normalizer" -v
pytest tests/ -k "amount" -v
```
## 🎯 测试最佳实践
### 1. 目录结构镜像源代码
测试目录结构镜像 `src/` 目录:
```
src/normalize/normalizers/amount_normalizer.py
tests/normalize/normalizers/test_amount_normalizer.py
```
### 2. 测试文件命名
- 测试文件以 `test_` 开头
- 测试类以 `Test` 开头
- 测试方法以 `test_` 开头
### 3. 使用 pytest fixtures
```python
@pytest.fixture
def normalizer():
"""Create normalizer instance for testing"""
return AmountNormalizer()
def test_something(normalizer):
result = normalizer.normalize('test')
assert 'expected' in result
```
### 4. 清晰的测试描述
```python
def test_with_comma_decimal(self, normalizer):
"""Amount with comma decimal should generate dot variant"""
result = normalizer.normalize('114,00')
assert '114.00' in result
```
### 5. Arrange-Act-Assert 模式
```python
def test_example(self):
# Arrange
input_data = 'test-input'
expected = 'expected-output'
# Act
result = process(input_data)
# Assert
assert expected in result
```
## 📝 添加新测试
### 为新功能添加测试
1. 在相应的 `tests/` 子目录创建测试文件
2. 遵循命名约定: `test_<module_name>.py`
3. 创建测试类和方法
4. 运行测试验证
示例:
```python
# tests/new_module/test_new_feature.py
import pytest
from src.new_module.new_feature import NewFeature
class TestNewFeature:
"""Test NewFeature functionality"""
@pytest.fixture
def feature(self):
"""Create feature instance for testing"""
return NewFeature()
def test_basic_functionality(self, feature):
"""Test basic functionality"""
result = feature.process('input')
assert result == 'expected'
def test_edge_case(self, feature):
"""Test edge case handling"""
result = feature.process('')
assert result == []
```
## 🔧 pytest 配置
项目的 pytest 配置在 `pyproject.toml`:
```toml
[tool.pytest.ini_options]
testpaths = ["tests"]
python_files = ["test_*.py"]
python_classes = ["Test*"]
python_functions = ["test_*"]
```
## 📈 持续集成
测试可以轻松集成到 CI/CD:
```yaml
# .github/workflows/test.yml
- name: Run Tests
run: |
conda activate invoice-py311
pytest tests/ -v --cov=src --cov-report=xml
- name: Upload Coverage
uses: codecov/codecov-action@v3
with:
file: ./coverage.xml
```
