Give a better error when rustdoc tests fail - Run the default rustdoc against the current rustdoc - Diff output recursively - Colorize diff output Closes https://github.com/rust-lang/rust/issues/78750. ## Resolved questions - Should this be opt-in instead of on by default? + No - Should this call through to `delta`? That's not a very common program to have installed, but I'm not sure how to do diffs after the fact. Maybe `compiletest` can take a `--syntax-highlighter` parameter or something? + I decided to use `delta` if available and `diff --color` otherwise. It prints a warning if delta isn't installed so you know you can get nicer diffs ## Open questions. - What version of rustdoc would this compare against? Ideally it would compare against `$(git merge-base HEAD origin/master)` - maybe that's feasible if we install those artifacts from CI? - Does it always make sense to compare the tests? Especially for new tests, I'm not sure how useful it would be ... but then again, one of the questions I want to know most as a reviewer is 'did it break before?'. r? `@GuillaumeGomez` cc `@Mark-Simulacrum`
