LLVM's lit tool for testing files is the most successful testing DSL I've ever seen. It's used a decent number of projects outside of LLVM. By contrast I don't see many folks using e.g. Cucumber these days.

Why do so few CLI tools use colour inside their error messages? For example, rustc uses colour well in the error display, but there's no special styling of the content in backticks. By contrast, markdown website almost always style backtick text differently from prose. E.g. `field` is not specially styled here.

@krinkle@mastodon.technology I don't know of anyone using difftastic by default, including me! (I use it >50% of the time though.) I toyed with background colours but I didn't find anything that I really liked. Contrast is hard, and depends on the user's theme. Background colours look bad with syntax highlighting (e.g. red background with blue comment text). It also looked silly due to ignoring whitespace between symbols. It's an interesting space and I'm still experimenting :)
