`evm blocktest` does not seem to output traces when `--debug` or `--json` are passed

[d-xo]

System information

Geth version: 1.11.6-stable
OS & Version: Linux

Expected behaviour

If I run evm --json statetest and pass a state test json, then evm will output per opcode traces, however running evm --json blocktest outputs nothing. The same is true when using --debug instead of --json. I would expect to be able to get json traces for both state and blockchain tests.

Actual behaviour

evm --json blocktest <FILE> and evm --debug blocktest <FILE> output nothing

Steps to reproduce the behaviour

evm --json blocktest <TEST_FILE>

[user@work go-ethereum]$ evm --json statetest  ./foo.txt
invalid character '\x1b' looking for beginning of value
[user@work go-ethereum]$ evm --json blocktest ./foo.txt
No help topic for 'blocktest'

There is no blocktest command. If you pass a blockchain test json to the statetest command, it will probably parse a statetest which is mostly empty, so no state transition to perform and no output to show.

There has been an evm blocktest since 1.11.0 I believe? It was added in the follwing pr: #26526.

Certainly it is present in the go-ethereum 1.11.6 I have installed locally:

> evm blocktest --help
NAME:
   evm blocktest - executes the given blockchain tests

USAGE:
   evm blocktest [command options] <file>

OPTIONS:

    --help, -h                     (default: false)
          show help

Oh, maybe I tested with some old version. Will recheck/reopen!

thanks for the fix! :)
