    # 初始化
    cmd_init([])

    # 测试性能

    elapsed = time.time() - start

    assert result == 0
    assert elapsed < 0.1  # 应该在 100ms 内完成
```

### 6.2 内存占用测试

```python
import psutil
import os

def test_memory_usage():
    """测试内存占用"""
    process = psutil.Process(os.getpid())
    mem_before = process.memory_info().rss / 1024 / 1024  # MB

    # 执行操作
    cmd_init([])

    mem_after = process.memory_info().rss / 1024 / 1024  # MB
    mem_used = mem_after - mem_before

    assert mem_used < 50  # 应该小于 50MB
```

---

## 七、测试覆盖率

### 7.1 覆盖率要求

- **核心模块**：≥ 80%
- **命令模块**：≥ 80%
- **工具模块**：≥ 70%
- **整体**：≥ 75%

### 7.2 运行覆盖率测试

```bash
# 运行测试并生成覆盖率报告
pytest --cov=src --cov-report=html --cov-report=term

# 查看覆盖率报告
open htmlcov/index.html
```

### 7.3 覆盖率配置

```ini
# .coveragerc
[run]
source = src
omit =
    */tests/*
    */venv/*
    */__pycache__/*

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

---

## 八、测试 Fixtures

### 8.1 conftest.py

```python
# tests/conftest.py
import pytest
from pathlib import Path
import shutil

@pytest.fixture
def temp_project(tmp_path):
    """创建临时项目目录"""
    project_dir = tmp_path / "test_project"
    project_dir.mkdir()
    return project_dir

@pytest.fixture
def initialized_project(temp_project, monkeypatch):
    """创建已初始化的项目"""
    monkeypatch.chdir(temp_project)
    from commands.init import cmd_init
    cmd_init([])
    return temp_project

@pytest.fixture
def sample_config():
    """示例配置"""
    return {
        "task": {
            "source": "task-now.md",
            "spec": "task-spec.md"
        },
        "env": {
            "python": {
                "version": ">=3.10",
                "venv": ".venv"
            }
        }
    }
```

---

## 九、持续集成

### 9.1 GitHub Actions 配置

```yaml
# .github/workflows/test.yml
name: Tests

on: [push, pull_request]

jobs:
  test:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
        python-version: ['3.10', '3.11', '3.12']

    steps:
    - uses: actions/checkout@v3

    - name: Set up Python
      uses: actions/setup-python@v4
      with:
        python-version: ${{ matrix.python-version }}

    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install pytest pytest-cov pytest-mock
        pip install tomli tomli-w

    - name: Run tests
      run: |
        pytest --cov=src --cov-report=xml

    - name: Upload coverage
      uses: codecov/codecov-action@v3
      with:
        file: ./coverage.xml
```

---

## 十、测试最佳实践

### 10.1 测试原则

1. **独立性**：每个测试独立运行，不依赖其他测试
2. **可重复性**：多次运行结果一致
3. **清晰性**：测试意图明确，易于理解
4. **快速性**：测试执行快速，及时反馈

### 10.2 测试模式

**AAA 模式**（Arrange-Act-Assert）：

```python
def test_example():
    # Arrange：准备测试数据
    config = {"task": {"source": "test.md"}}

    # Act：执行操作
    result = get_config_value(config, "task.source")

    # Assert：验证结果
    assert result == "test.md"
```

### 10.3 Mock 使用

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

def test_with_mock(monkeypatch):
    """使用 mock 测试"""
    # Mock 函数
    mock_func = Mock(return_value=True)
    monkeypatch.setattr("module.function", mock_func)

    # 执行测试
    result = some_function()

    # 验证 mock 被调用
    mock_func.assert_called_once()
```
