Generate Comprehensive Unit Tests for Any Function

💡 Pro Tips

• •Include any types/interfaces the function uses for more accurate test generation
• •Mention dependencies that need mocking — the AI will set up proper mocks
• •Ask for 'mutation testing ideas' as a follow-up to find weak tests

🧠 Why This Works

Comprehensive tests require thinking about edge cases, boundary conditions, and failure modes that developers often overlook. This prompt systematically generates tests covering happy paths, error cases, and corner cases to achieve meaningful code coverage.

📅 When to Use This Prompt

Use when writing tests for existing untested code, when you need to quickly bootstrap a test suite for a new function or module, or when you want to ensure edge cases like null inputs, empty arrays, and boundary values are covered.

🎯 What You'll Get

You'll get a complete test suite with descriptive test names, proper arrange-act-assert structure, mock setup for dependencies, edge case coverage, and tests organized by behavior—ready to run with your testing framework.
