tdd-test-writer

Developer Tools

Gives your agent the ability to write failing tests first, creating a strict behavior contract for test-driven development.

When to use

  • When starting a new feature using a test-first workflow

  • When fixing a bug that requires a regression test first

  • When creating automated tests to gate implementation quality

How to use

  1. 1

    Identify the target files and specific behavior you want to test

  2. 2

    Convert your requirements into explicit acceptance criteria for the code

  3. 3

    Run the agent to author behavior-focused tests in the RED phase

  4. 4

    Verify that the new tests fail for the correct behavioral reasons

I need to add a new 'calculateDiscount' function. Can you write the tests first using TDD?

tdd-test-writer

Agent

I will create a new test file that defines the behavior for your discount logic, covering the happy path and edge cases like zero or negative inputs. I'll verify these tests fail initially because the function doesn't exist yet, then provide a strict implementation contract for the next agent to satisfy without modifying my tests.
