Install and run

Setup complexity: low.

clawhub skill install s17fm1dbahvthhc4atzm70t6v585c74c:python-testing

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Python Testing

Python 测试框架核心用法速查。

## 快速参考

### pytest 基础
```bash
pytest                        # 运行所有测试
pytest -v                     # 详细输出
pytest test_module.py         # 指定文件
pytest -k "login"             # 匹配测试名
pytest -x                     # 失败时停止
pytest -n 4                   # 并行执行
```

### 测试示例
```python
def test_addition():
    assert 1 + 1 == 2

@pytest.mark.parametrize("a,b,expected", [(1,2,3), (2,3,5)])
def test_add(a, b, expected):
    assert add(a, b) == expected
```

### Mock
```python
from unittest.mock import Mock, patch

mock_db = Mock()
mock_db.query.return_value = []

@patch('module.function')
def test_with_mock(mock_func):
    mock_func.return_value = 42
```

### Fixture
```python
@pytest.fixture
def database():
    db = Database(":memory:")
    yield db
    db.close()

def test_query(database):
    assert database.query("SELECT 1")
```

### 覆盖率
```bash
pytest --cov=myapp
pytest --cov=myapp --cov-report=html
```

## 详细参考

- **Mock 和 Patch**: [references/mocking.md](references/mocking.md) - unittest.mock 详解
- **Fixtures**: [references/fixtures.md](references/fixtures.md) - fixture 高级用法
- **异步测试**: [references/async.md](references/async.md) - pytest-asyncio
- **覆盖率**: [references/coverage.md](references/coverage.md) - pytest-cov 配置

## 常用标记

```python
@pytest.mark.slow              # 标记慢测试
@pytest.mark.integration       # 标记集成测试
@pytest.mark.skip(reason="TODO")
@pytest.mark.skipif(sys.version_info < (3, 10))
```

## pytest.ini 配置

```ini
[pytest]
testpaths = tests
python_files = test_*.py
markers =
    slow: marks tests as slow
    integration: integration tests
addopts = -v --tb=short
```

references/async.md

# 异步测试

## pytest-asyncio

```bash
pip install pytest-asyncio
```

```python
import pytest

@pytest.mark.asyncio
async def test_async_function():
    result = await async_operation()
    assert result == "expected"

@pytest.mark.asyncio
async def test_async_with_mock():
    with pytest.raises(ValueError):
        await async_function_that_raises()
```

## 异步 Fixture

```python
@pytest.fixture
async def async_client():
    client = await create_async_client()
    yield client
    await client.close()

@pytest.mark.asyncio
async def test_with_async_fixture(async_client):
    result = await async_client.get("/")
    assert result.status == 200
```

## httpx 异步测试

```python
import pytest
from httpx import AsyncClient, ASGITransport
from myapp import app

@pytest.fixture
async def client():
    async with AsyncClient(
        transport=ASGITransport(app=app),
        base_url="http://test"
    ) as client:
        yield client

@pytest.mark.asyncio
async def test_api(client):
    response = await client.get("/users")
    assert response.status_code == 200
```

references/coverage.md

# 覆盖率测试

## pytest-cov

```bash
pip install pytest-cov
```

## 运行覆盖率

```bash
pytest --cov=myapp
pytest --cov=myapp --cov-report=term-missing
pytest --cov=myapp --cov-report=html
pytest --cov=myapp --cov-fail-under=80
pytest --cov=myapp --cov-branch
```

## .coveragerc 配置

```ini
[run]
source = myapp
branch = True
omit =
    */tests/*
    */__init__.py

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

## pyproject.toml 配置

```toml
[tool.coverage.run]
source = ["myapp"]
branch = true
omit = ["*/tests/*"]

[tool.coverage.report]
exclude_lines = [
    "pragma: no cover",
    "def __repr__",
    "raise NotImplementedError",
]
```

# Fixtures

## 基本 Fixture

```python
import pytest

@pytest.fixture
def database():
    db = Database(":memory:")
    db.connect()
    yield db
    db.close()

def test_query(database):
    result = database.query("SELECT 1")
    assert result is not None
```

## Fixture 依赖

```python
@pytest.fixture
def database():
    return Database(":memory:")

@pytest.fixture
def user(database):
    return database.create_user(name="Alice")

def test_user_name(user):
    assert user.name == "Alice"
```

## 作用域

```python
# function: 每个测试调用一次 (默认)
# class: 每个测试类调用一次
# module: 每个模块调用一次
# package: 每个包调用一次
# session: 整个测试会话调用一次

@pytest.fixture(scope="module")
def app():
    app = create_app()
    app.start()
    yield app
    app.stop()

@pytest.fixture(scope="session")
def docker_client():
    client = DockerClient()
    yield client
    client.close()
```

## autouse

```python
# 自动使用
@pytest.fixture(autouse=True)
def setup_teardown():
    print("Setup")
    yield
    print("Teardown")
```

## 参数化

```python
@pytest.fixture(params=["sqlite", "postgres"])
def database(request):
    db = create_database(request.param)
    yield db
    db.close()

def test_with_multiple_dbs(database):
    # 会运行两次
    pass
```

## conftest.py

```python
# tests/conftest.py - 共享 fixture

import pytest

@pytest.fixture
def client():
    app = create_app()
    with app.test_client() as client:
        yield client

@pytest.fixture
def auth_header():
    token = create_test_token()
    return {"Authorization": f"Bearer {token}"}
```
