As seen in my code at https://public-inbox.org/git/87zhnuwdkp....@evledraar.gmail.com/ our test suite emits various lines of JSON that aren't even validly encoded, so I can't imagine we're passing any sort of proper parser validatior, let alone a schema validator. In terms of implementation I think it would make sense to have a *.sh wrapper for this already, then we could test via prereqs if we have some of the existing validators (seems there's a list at https://json-schema.org/implementations.html) and e.g. run a dummy test against some small list of git commands, and then you could also pass it an env variable with "here's the trace file" so you could do: GIT_TRACE2_EVENT=/tmp/git.events prove <all testss> && VALIDATE_THIS=/tmp/git.events ./<that new test>.sh And it would validate that file, if set.
