Prompt

Write unit tests for this {{language}} function using {{test_framework}}:

```
{{paste your code}}
```

Cover:
- Happy path with typical inputs
- Edge cases (empty input, null, boundary values)
- Error cases (invalid input, expected exceptions)

Use descriptive test names that explain the expected behavior. Follow the Arrange-Act-Assert pattern. Do not mock anything unless absolutely necessary.

Variables to customize

Why this prompt works

Specifying test framework ensures correct syntax. The 'do not mock unless necessary' instruction prevents both models from creating brittle, over-mocked tests.
