1. Write test that generates an artefact (e.g. picture) where you can check look and feel (red).

2. Write code that makes it look right, running the test and checking that picture periodically. When it looks right, lock in the artefact which should now be checked against the actual picture (green, if it matches).

3. Refactor.

The only criticism ive heard of this is that it doesnt fit some people's conceptions of what they think TDD "ought to be" (i.e. some bullshit with a low level unit test).

You can even do this with LLM as a judge as well. Feed screenshots into a LLM as a judge panel and get them to rank the design 1-10. Give the LLM judge panel a few different perspectives/models to get a good distribution of ranks, and establish a rank floor for test passing.

Parent mentioned "subjective look and feel", LLMs are absolutely trash at that and have no subjective taste, you'll get the blandest designs out of LLMs, which makes sense considering how they were created and trained.

That only works for the simplest minimally interactive examples.

It is also so monumentally brittle that if you do this for interactive software, you will drive yours nuts trying.
