Generate pytest unit tests instantly with AI. Right-click any Python file → tests written in seconds, covering happy paths, edge cases, and null inputs.

No more staring at a blank test_ file. TestPilot reads your functions and writes the tests for you.

⚡ How It Works

1. Open any .py file in VS Code
2. Right-click → TestPilot AI: Generate Tests for This File
3. Tests are written to tests/ai_generated/test_ai_<yourfile>.py and opened automatically

That's it.
