test-driven-development

Developer Tools

Gives your agent the ability to strictly follow the Red-Green-Refactor cycle to ensure every line of code is verified.

When to use

  • When implementing any new feature to ensure behavioral correctness

  • When fixing a bug by first reproducing it with a failing test

  • When refactoring existing code to maintain a safety net of automated tests

How to use

  1. 1

    Write a minimal failing test that defines the expected new behavior

  2. 2

    Verify the test fails for the correct reason (missing implementation)

  3. 3

    Write the simplest possible production code to make the test pass

  4. 4

    Clean up and refactor the code while ensuring all tests stay green

I want to add a feature that retries failed API calls three times.

Agent

I'll start by writing a failing test that expects a successful result after two simulated failures. After verifying it fails correctly, I'll implement the minimal retry logic in your production code. Finally, once the test passes, I'll refactor the code for better readability while ensuring the retry behavior remains fully verified.
