Does this actually work for you? As seen in my code at
https://public-inbox.org/git/87zhnuwdkp.fsf@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.
