  • Prompt-injection patterns
  • Secret / credential exfiltration
  • Dangerous shell & filesystem operations
  • Untrusted network calls
  • Known-malicious package signatures

What it can access

  • Network access No
  • Filesystem access No
  • Shell / process execution No
  • Environment & secrets No
  • Dynamic code execution No

From automated source analysis of v0.1.0. “Used” means the capability is present in the source — more access means more to trust, not that it’s unsafe.

About

Unit Test Generator

> 根据源代码自动生成单元测试,支持多种语言和测试框架。 > > Automatically generate unit tests based on source code, supporting multiple languages and testing frameworks.

When to Use

当用户请求以下操作时使用此 skill:

  • 生成单元测试 / Generate unit tests
  • 为函数/类编写测试 / Write tests for functions/classes
  • 创建测试用例 / Create test cases
  • 提高代码覆盖率 / Improve code coverage

Instructions

分析步骤 / Analysis Steps

  1. 识别代码 - 确定编程语言和代码结构
  2. 分析功能 - 理解函数/方法的输入、输出和行为
  3. 确定边界 - 识别边界条件和边缘情况
  4. 选择框架 - 根据语言选择合适的测试框架
  5. 生成测试 - 编写全面的测试用例

支持的语言和框架 / Supported Languages

| 语言 | 测试框架 | |------|----------| | Python | pytest, unittest | | JavaScript/TypeScript | Jest, Mocha, Vitest | | Java | JUnit, TestNG | | Go | testing (built-in) | | Rust | cargo test (built-in) |

测试类型 / Test Types

  • 正常路径测试 - 验证预期行为
  • 边界条件测试 - 测试边界值
  • 异常处理测试 - 验证错误处理
  • 空值/空输入测试 - 处理空值情况

输出格式 / Output Format

使用 templates/test-report.md 模板格式化输出。

Use the templates/test-report.md template to format output.

输出 / Output

单元测试生成报告

分析概述

divide 函数执行除法运算,包含除零检查。需要测试正常除法、除零异常、边界值等情况。

生成的测试

import pytest
from your_module import divide

class TestDivide:
    """Tests for the divide function."""

    def test_divide_positive_numbers(self):
        """Test division of positive numbers."""
        assert divide(10, 2) == 5.0
        assert divide(7, 2) == 3.5

    def test_divide_negative_numbers(self):
        """Test division with negative numbers."""
        assert divide(-10, 2) == -5.0
        assert divide(10, -2) == -5.0
        assert divide(-10, -2) == 5.0

    def test_divide_by_zero_raises_error(self):
        """Test that dividing by zero raises ValueError."""
        with pytest.raises(ValueError, match="Cannot divide by zero"):
            divide(10, 0)

    def test_divide_zero_numerator(self):
        """Test division when numerator is zero."""
        assert divide(0, 5) == 0.0

    def test_divide_float_precision(self):
        """Test division with floating point numbers."""
        assert divide(1, 3) == pytest.approx(0.333333, rel=1e-5)

测试覆盖说明

  • ✅ 正常正数除法
  • ✅ 负数除法
  • ✅ 除零异常
  • ✅ 分子为零
  • ✅ 浮点精度
