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.
当用户请求以下操作时使用此 skill：
| 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) |
使用 templates/test-report.md 模板格式化输出。
Use the templates/test-report.md template to format output.

def divide(a: float, b: float) -> float:
if b == 0:
raise ValueError("Cannot divide by zero")
return a / b
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。
