If I cannot write shader code without broken tests, there is a bunch of yak shaving to make testing possible in first place, and that only covers a small subset of graphics pipeline features.

It also takes zero consideration for the interactive nature of games/graphics development.

I can't immediately think of what a useful shader test would look like (beyond perhaps, shader doesn't crash program) - if this is something worth discussing, it would probably be useful to see some real world shader code; perhaps especially two versions of the same shader as it evolve.

I don't generally test css code to check that a background is now indeed set to "a more mauvey shade of pinky-russet" after a change - but I might want to.

I might at least want to run a test with browser automation to check that any text is readable on the background.

I could at least find an example of looking at the rendered page for text (as opposed to in the DOM); Google AI had some ideas of how to check the contrast in a screenshot - but no idea if that would actually work as written.

yes, there is some yak shaving necessary to make writing tests possible.

There is often a tension between delivering fast and high quality/bug free and what is necessary for medical software or financial calculations might not be necessary for games.

The question of whether to write tests at all is not really about TDD though.
