How to use Claude Code test-first

A failing test turns the requested behaviour into evidence before generated code expands the diff.

  1. 01

    Choose one behaviour

    Write a precise acceptance example and identify the appropriate test layer.

  2. 02

    Confirm the failure

    Add the test and run it to prove it fails for the expected reason.

  3. 03

    Implement and refactor

    Make the smallest passing change, then clean up while keeping tests green.
